FIG. 1A is a simplified schematic diagram of a first embodiment of the valve of the present application, showing the schematic structure from a side perspective; FIG. 1B is a simplified cross-sectional structural schematic view of the valve 100 shown in FIG. 1A taken along line A-A in FIG. 1A. As shown in fig. 1A and 1B, the valve 100 includes a housing 101, the housing 101 having a housing cavity 102 therein. The housing 101 is provided with four housing openings, namely a first housing opening 151, a second housing opening 152, a third housing opening 153 and a fourth housing opening 154. The housing plenum 102 can be in fluid communication with the exterior of the valve 100 through any one of the first housing opening 151, the second housing opening 152, the third housing opening 153, and the fourth housing opening 154.
The valve 100 also includes a first set of valve body members 111 and a second set of valve body members 112.

Wherein the first valve body 121 is spherical and provided with a first valve body passage (not shown). One end of the first-valve-body passage forms a valve-body opening portion 161 on the first valve body 121. The first valve body passage can be in fluid communication with the housing pocket 102.

Wherein the third valve body 123 is spherical and is provided with a third valve body passage (not shown). One end of the third valve body passage forms a valve body opening portion 163 on the third valve body 123. The third valve body passage can be in fluid communication with the housing plenum 102. When the valve body opening portion 163 of the third valve body 123 is aligned or partially aligned with the third housing opening 153, the third housing opening 153 is opened by the third valve body 123, and the housing receptacle 102 is capable of fluid communication with the outside through the valve body opening portion 163 and the third housing opening 153. And when the valve body opening portion 163 on the third valve body 123 is not aligned with the third housing opening 153, the third housing opening 153 is closed or blocked by the third valve body 123 such that the housing pocket 102 cannot be in fluid communication with the outside through the valve body opening portion 163 and the third housing opening 153. The fourth valve body 124 is spherical and is provided with a fourth valve body passage (not shown). One end of the fourth valve body passage forms a valve body opening portion 164 in the fourth valve body 124. The fourth valve body passage can be in fluid communication with housing plenum 102. When valve body opening portion 164 of fourth valve body 124 is aligned or partially aligned with fourth housing opening 154, fourth housing opening 154 is opened by fourth valve body 124 and housing receptacle 102 is capable of fluid communication with the ambient through valve body opening portion 164 and fourth housing opening 154. And when valve body opening portion 164 on fourth valve body 124 is not aligned with fourth housing opening 154, fourth housing opening 154 is closed or blocked by fourth valve body 124 such that housing plenum 102 is not able to fluidly communicate with the ambient through valve body opening portion 164 and fourth housing opening 154.
The valve 100 also includes seals 171,172,173, 174.

When the drive shaft 118 rotates in the angular range of 75-100%, the area of alignment between the valve body opening portion 164 of the fourth valve body 124 and the fourth housing opening 154 gradually increases, so that the opening degree of the fourth housing opening 154 gradually changes from 0% to 100%.
To achieve the opening degree control shown in fig. 2, the valve 100 may be configured to: when the driving shaft 118 rotates in the angular ranges of 0-25% and 50-75%, the first valve body 121 and the second valve body 122 are driven to rotate by the driving shaft 118, and the third valve body 123 and the fourth valve body 124 are not driven to rotate by the driving shaft 118; when the driving shaft 118 rotates in the angular ranges of 25-50% and 75-100%, the first and second valve bodies 121 and 122 are not driven to rotate by the driving shaft 118, and the third and fourth valve bodies 123 and 124 are driven to rotate by the driving shaft 118. That is, when the driving shaft 118 rotates in the angular ranges of 0-25% and 50-75%, the driving shaft 118 is engaged with the first group valve body part 111, but is separated from the second group valve body part 112; when the drive shaft 118 rotates through the angular ranges of 25-50% and 75-100%, the drive shaft 118 is disengaged from the first set of valve body members 111, but is engaged with the second set of valve body members 112.
The respective housing openings 151,152,153,154 of the valve 100 are connected to external piping, respectively, and the open and closed states of the respective housing openings 151,152,153,154 can be controlled by controlling the rotation of the respective valve bodies 121,122,123, and 124 with respect to the housing 101. By controlling the open and closed states of the respective housing openings 151,152,153,154 and the interfitting between the valve bodies 121,122,123 and 124, several fluid passages can be formed in the valve 100, each for communicating with a respective two housing openings, so that the external conduits connected to the two respective housing openings can be communicated through the fluid passages. The several fluid passages in the valve 100 can be switched on or off by controlling the rotation of the respective valve bodies.
To better illustrate the fluid passages within the valve, reference is made below in connection with fig. 1A and 2 to the state of the drive shaft 118 at angles of 50% and 75%, respectively, as an example:
if the first housing opening 151 is in communication with the coolant inlet line and the other three housing openings 152,153,154 are in communication with the three coolant outlet lines, respectively, the valve 100 may be configured such that three fluid passages a, B, and C can be formed in the valve 100. Wherein the fluid passage a communicates with the first and second housing openings 151 and 152, the fluid passage B communicates with the first and third housing openings 151 and 153, and the fluid passage C communicates with the first and fourth housing openings 151 and 154.
When the drive shaft 118 is at an angle of 50%, the valve body opening portion 161 on the first valve body 121 is aligned with the first housing opening 151, so that the first housing opening 151 is opened; the valve body opening portion 163 on the third valve body 123 is aligned with the third housing opening 153, so that the third housing opening 153 is opened; while the valve body opening portion 162 on the second valve body 122 is not aligned with the second housing opening 152 such that the second housing opening 152 is closed or blocked and the valve body opening portion 164 of the fourth valve body 124 is not aligned with the fourth housing opening 154 such that the fourth housing opening 154 is closed or blocked. At this time, the fluid passage B communicating the first and third housing openings 151 and 153 is turned on, and the fluid passage a communicating the first and second housing openings 151 and 152, and the fluid passage C communicating the first and fourth housing openings 151 and 154 are turned off.
When the drive shaft 118 is at an angle of 75%, the valve body opening portion 161 on the first valve body 121 is aligned with the first housing opening 151, so that the first housing opening 151 is opened; the valve body opening portion 162 on the second valve body 122 is aligned with the second housing opening 152 such that the second housing opening 152 is opened; the valve body opening portion 163 on the third valve body 123 is aligned with the third housing opening 153, so that the third housing opening 153 is opened; and valve body opening portion 164 of fourth valve body 124 is misaligned with fourth housing opening 154 such that fourth housing opening 154 is closed or blocked. At this time, the fluid passage B communicating the first and third housing openings 151 and 153, and the fluid passage a communicating the first and second housing openings 151 and 152 are turned on, and the fluid passage C communicating the first and fourth housing openings 151 and 154 is turned off.
It should be noted that in the first embodiment, the valve body opening portions 161,162,163,164 of each valve body form valve body acting portions for cooperating with a corresponding one of the plurality of housing openings when the driven valve body member is rotated by a predetermined angle, thereby selectively opening at least one of the fluid passages. In other embodiments, the valve body actuation portion may also be a valve body blocking portion for interacting with at least one of the plurality of housing openings when the driven valve body member is rotated a predetermined angle such that the valve body blocking portion selectively blocks the at least one of the plurality of housing openings to selectively block the at least one fluid passageway. This will be explained in detail in the embodiment shown in fig. 25A-25C.

It should be noted that the shape of the valve body is not limited to the spherical shape and the hemispherical shape exemplified in the present application, but may be any shape as long as the valve body has a valve body passage therein and has a corresponding valve body opening portion.
FIG. 5A is a simplified schematic diagram of a fourth embodiment of the valve of the present application, showing the schematic structure from a side perspective; FIG. 5B is a simplified cross-sectional structural schematic view of the valve 500 shown in FIG. 5A taken along line B-B in FIG. 5A. The valve 500 shown in FIGS. 5A-5B is identical to the valve 100 shown in FIGS. 1A-1B and will not be described in detail herein. The valve 500 shown in FIGS. 5A-5B differs from the valve 100 shown in FIGS. 1A-1B primarily in that: the valve 500 shown in fig. 5A-5B further includes a third set of valve body members 513 and third clutching structure 543 cooperating therewith.
Specifically, third set of valve body components 513 includes a fifth valve body 525 and a sixth valve body 526. The fifth valve body 525 and the sixth valve body 526 are connected to each other and are rotatable together about a rotation axis 533. Wherein the fifth valve body 525 and the sixth valve body 526 are both spherical and have respective valve body passages (not shown). One end of a valve body passage (not shown) forms a valve body opening portion 565 and a valve body opening portion 566 in the fifth valve body 525 and the sixth valve body 526, respectively.
Correspondingly, the housing 501 further includes a fifth housing opening 555 and a sixth housing opening 556, which are respectively alignable with the valve body opening portions 565,566 of the third set of valve body members 513.

The first, second, and third clutch structures 141, 142, and 543 are disposed at the same height with respect to the driving shaft 118.
In the embodiment shown in fig. 1A-5B, the various clutching features and sets of valve body components are disposed at approximately the same height relative to the drive shaft 118. Such an arrangement enables the height of the valve 100 to be small, and thus can be suitable for use in applications where the height of the valve is limited.
FIG. 6A is a simplified schematic diagram of a fifth embodiment of the valve of the present application, showing the schematic structure from a side perspective; FIG. 6B is a simplified cross-sectional structural schematic view of the valve 600 shown in FIG. 6A taken along line C-C in FIG. 6A. The valve 600 shown in FIGS. 6A-6B is identical to the valve 100 shown in FIGS. 1A-1B and will not be described in detail herein. The valve 600 shown in FIGS. 6A-6B differs from the valve 100 shown in FIGS. 1A-1B in that: each of the sets of valve body components in the valve 600 shown in fig. 6A-6B includes only one valve body component, and the sets of valve body components and their corresponding clutching structures are disposed at different heights relative to the drive shaft 118.
Specifically, the valve 600 includes a first valve body 621, a second valve body 622, a third valve body 623, a fourth valve body 624, and a first clutch structure 641, a second clutch structure 642, a third clutch structure 643, and a fourth clutch structure 644 which are provided in correspondence thereto. The specific fitting relationship between the first valve body 621, the second valve body 622, the third valve body 623 and the fourth valve body 624 and the housing 601 is substantially the same. The following description will be made by taking specific matching relationships among the first valve body 621, the first clutch structure 641 and the housing 601 as examples:
the first valve body 621 is spherical and can rotate about a rotational axis 631. The first valve body 621 is provided with a valve body opening portion 661 capable of aligning with the first housing opening 651 on the housing 601. A seal 671 is disposed within the housing 601 and is disposed around the housing opening 651 for sealing a gap between the first housing opening 651 and the first valve body 621.
The first clutching structure 641 includes a first clutchable drive structure 681 and a first clutchable driven structure 691. A first clutchable drive structure 681 is provided on the disk 611. A first disengageable driven structure 691 is provided on the first valve body 621. The first clutched drive structure 681 and the first clutched driven structure 691 are configured to cooperate such that when the drive shaft 118 is rotated within a first angular range, the drive shaft 118 can engage the first valve body 621 such that the first clutched drive structure 681 on the drive shaft 118 can rotate the first valve body 621.

Fig. 7 is a schematic illustration of one embodiment of the relationship of the degree of rotation of the drive shaft 118 to the opening of the housing opening 651,652,653,654 shown in fig. 6A-6B. In the embodiment of fig. 7, a 100% angle represents a 360 ° rotational angle of the drive shaft 118, 100% when the housing opening 651,652,653,654 is fully opened by the corresponding valve body and 0% when the housing opening 651,652,653,654 is fully closed or blocked by the corresponding valve body. It will be appreciated by those skilled in the art that a 100% angle may also mean that the drive shaft 118 may be rotated through an angle of 90 °, 180 °, or any other angle.
As shown in fig. 7, when the drive shaft 118 rotates in an angular range of 0 to 25%, the area of alignment between the valve body opening portion 661 of the first valve body 621 and the first housing opening 651 gradually increases, so that the opening degree of the first housing opening 651 gradually changes from 0% to 100%. When the drive shaft 118 is rotated in an angular range of 25 to 100%, the valve body opening portion 661 of the first valve body 621 and the first housing opening 651 are always aligned, and the opening degree of the first housing opening 651 is maintained at 100%.
Similarly, with respect to the second housing opening 652, when the drive shaft 118 rotates in the angular range of 0 to 50%, the area of alignment between the valve body opening portion 662 of the second valve body 622 and the second housing opening 652 is 0%, the second housing opening 652 is closed or blocked by the second valve body 622, and the opening degree of the second housing opening 652 is maintained at 0%. When the drive shaft 118 rotates in an angular range of 50-75%, the area of alignment between the valve body opening portion 662 of the second valve body 622 and the second housing opening 652 gradually increases, so that the opening degree of the second housing opening 652 gradually changes from 0% to 100%. When the drive shaft 118 rotates in an angular range of 75 to 100%, the valve body opening portion 662 of the second valve body 622 and the second housing opening 652 are always aligned, and the opening degree of the second housing opening 652 is maintained at 100%.
Similarly, with respect to the third housing opening 653, when the drive shaft 118 rotates in the angular range of 0 to 25%, the area of alignment between the valve body opening portion 663 of the third valve body 623 and the third housing opening 653 is 0%, the third housing opening 653 is closed or blocked by the third valve body 623, and the opening degree of the third housing opening 653 is maintained at 0%. When the drive shaft 118 rotates in an angular range of 25 to 50%, the area of alignment between the valve body opening portion 663 of the third valve body 623 and the third housing opening 653 gradually increases, so that the opening degree of the third housing opening 653 gradually changes from 0% to 100%. When the drive shaft 118 is rotated in an angular range of 50 to 100%, the valve body opening portion 663 and the third housing opening 653 are always aligned, and the opening degree of the third housing opening 653 is maintained at 100%.
Similarly, for the fourth housing opening 654, when the drive shaft 118 is rotated through an angular range of 0-75%, the area of alignment between the valve body opening portion 664 of the fourth valve body 624 and the fourth housing opening 654 is 0%, and the fourth housing opening 654 is closed or blocked by the fourth valve body 124, with the degree of opening remaining 0%. When the drive shaft 118 rotates in the angular range of 75-100%, the area of alignment between the valve body opening portion 664 of the fourth valve body 624 and the fourth housing opening 654 gradually increases, so that the opening degree of the fourth housing opening 654 gradually changes from 0% to 100%.
To achieve the opening degree control shown in fig. 2, the valve 100 may be configured to: when the drive shaft 118 rotates in the angular range of 0 to 25%, the drive shaft 118 engages with the first valve body 621 but is separated from the second valve body 622, the third valve body 623, and the fourth valve body 624, so that the first valve body 621 is driven to rotate by the drive shaft 118, and the second valve body 622, the third valve body 623, and the fourth valve body 624 are not driven to rotate by the drive shaft 118; when the drive shaft 118 rotates in an angular range of 25 to 50%, the drive shaft 118 engages with the third valve body 623 but is separated from the first valve body 621, the second valve body 622, and the fourth valve body 624, so that the third valve body 623 is driven to rotate by the drive shaft 118, and the first valve body 621, the second valve body 622, and the fourth valve body 624 are not driven to rotate by the drive shaft 118; when the drive shaft 118 rotates in an angular range of 50 to 75%, the drive shaft 118 engages with the second valve body 622 but is separated from the first valve body 621, the third valve body 623, and the fourth valve body 624, so that the second valve body 622 is driven to rotate by the drive shaft 118, while the first valve body 621, the third valve body 623, and the fourth valve body 624 are not driven to rotate by the drive shaft 118; when the drive shaft 118 rotates within an angular range of 75-100%, the drive shaft 118 engages with the fourth valve body 6243 but disengages from the first, second, and third valve bodies 621,622,623 such that the fourth valve body 624 is driven to rotate by the drive shaft 118 while the first, second, and third valve bodies 621,622,623 are not driven to rotate by the drive shaft 118.
The respective housing openings 651,652,653,654 of the valve 600 are connected to external piping, respectively, and by controlling the rotation of the respective valve bodies 621,622,623,624 with respect to the housing 101, the open and closed states of the respective housing openings 651,652,653,654 can be controlled. By controlling the opening and closing states of the respective housing openings 651,652,653,654 and the mutual cooperation between the valve bodies 621,622,623,624, a plurality of fluid passages each for communicating with the corresponding two housing openings can be formed in the valve 600, so that the external lines connected to the two corresponding housing openings can be communicated through the fluid passages. The several fluid passages in the valve 600 can be switched on or off by controlling the rotation of the respective valve bodies.
FIG. 8 is a simplified schematic illustration of a sixth embodiment of the valve of the present application. The valve 800 shown in fig. 8 is identical to the valve 600 shown in fig. 6A-6B and will not be described in detail herein. The valve 800 shown in fig. 8 differs from the valve 600 shown in fig. 6A-6B in that: the first valve body 821, the second valve body 822, the third valve body 823 and the fourth valve body 824 in the valve 800 shown in fig. 8 are hemispherical, and the first valve body 621, the second valve body 622, the third valve body 623 and the fourth valve body 624 in the valve 600 shown in fig. 6A to 6B are spherical.
FIG. 9 is a simplified schematic illustration of a seventh embodiment of the valve of the present application. As shown in fig. 9, the valve 900 includes six sets of valve body components. Wherein each of the first and second sets of valve body components 911 and 912, respectively, includes two interconnected valve bodies. The mating relationship between the first and second sets of valve body members 911 and 912, the clutch features, and the housing 901 are similar to the valve 100 of FIGS. 1A-1B and will not be described in detail herein.
The valve 900 also includes four additional sets of valve body components. Each of the four sets of valve body members includes only one valve body member and the corresponding clutch features of each set of valve body members are disposed at different heights relative to the drive shaft 118. Specifically, the valve body components included in each of the four valve body components are: a third valve body member 921, a fourth valve body member 922, a fifth valve body member 923, and a sixth valve body member 924. The mating relationship between the third, fourth, fifth and sixth valve body members 921, 922, 923, 924, the clutch structure and the housing 901 is similar to the valve 600 of fig. 6A-6B and will not be described in detail herein.
Fig. 10 is a schematic diagram of one embodiment of the relationship of the angle of rotation of the drive shaft 118 to the opening of the housing opening 151,152,153,154,651,652,653,654 shown in fig. 9. The relationship between the rotation angle of the driving shaft 118 and the housing opening 151,152,153,154,651,652,653,654 shown in fig. 10 is similar to that shown in fig. 2 and 7, and the opening and closing of the housing opening 151,152,153,154,651,652,653,654 can be performed to open or close different fluid passages in the valve body 900, which is not described in detail herein.
In the embodiment shown in fig. 6A-10, the various clutching features are provided at different heights relative to the drive shaft 118. Such an arrangement enables the valve 100 to have a small circumferential dimension, and thus can be applied to an application environment in which the circumferential dimension of the valve is limited.
It should be noted that although only one valve body opening portion is provided on each valve body member in the embodiments shown in fig. 1A to 10, it will be understood by those skilled in the art that a plurality of valve body opening portions may be provided on each valve body member so that different valve body opening portions function when the drive shaft is rotated to different angular ranges.
The valves shown in fig. 1A to 10 can make the driving shaft selectively drive at least one set of valve body of the sets of valve body components to rotate through a plurality of clutch structures, so as to connect or disconnect at least one fluid passage of a plurality of fluid passages in the valve body. Because the driving shaft selectively drives at least one group of valve bodies in the plurality of groups of valve body components to rotate at the same time, the driving shaft only needs to overcome the friction force generated by the sealing elements between the driven at least one group of valve bodies and the shell, so that the valve body provided with a plurality of sealing elements can be driven to rotate when the output power of the actuator 190 is small. When the valve is required to provide more fluid passages, more housing openings are required in the housing of the valve, and the more housing openings, the more number of seals. The valve provided herein is particularly well suited for applications where more fluid passages are provided for a given output of the actuator because the drive shaft of the valve of the present application need only overcome the friction created by the seals between at least one of the valve bodies and the housing being actuated, and need not simultaneously overcome the friction created by all of the seals between the valve bodies and the housing, and therefore, need not increase the output of the actuator 190 with increased fluid passages within the valve.
The mating relationship of the housing, valve body components and clutch structure is shown in one embodiment with reference to fig. 11A-24.
FIG. 11A is a perspective view of a valve 1100 according to an eighth embodiment of the present application; FIG. 11B is an exploded view of the valve 1100 shown in FIG. 11A; FIG. 11C is a vertical downward cross-sectional view of the valve 1100 shown in FIG. 11A, as taken along section line D-D in FIG. 11A. The seals provided at the openings of each housing are not shown in fig. 11A-11C to clearly illustrate the major components of the valve 1100. As shown in fig. 11A-11C, valve 1100 includes a housing 1101, a first valve body 1132, a second valve body 1134, a third valve body 1136, and a fourth valve body 1138. Housing 1101 has a first volume 1112 and a second volume 1114. First, second, and fourth valve bodies 1132, 1134, 1138 are disposed in the first volume 1112, and a third valve body 1136 is disposed in the second volume 1114. A sleeve 1155 is disposed at the bottom of the rotating shaft 1162 of the first valve body 1132, and the sleeve 1155 is sleeved on the top of the rotating shaft 1164 of the second valve body 1134, so that the first valve body 1132 and the second valve body 1134 can rotate around the same first axis X. The lower portion of the rotation shaft 1166 of the third valve body 1136 passes through the first transverse partition plate 1120 of the first cavity 1112 and the second cavity 1114 and then extends into the first cavity 1112. The bottom of the third valve body 1136 is provided with a sleeve 1156, and the sleeve 1156 is sleeved on the top of the rotating shaft 1168 of the fourth valve body 1138, so that the third valve body 1136 and the fourth valve body 1138 can rotate around the same second axis Y.
The valve 1100 also includes a drive shaft 1118. The drive shaft 1118 is disposed in the first cavity 1112 and is rotatable about a third axis Z. Wherein the first valve body 1132 and the second valve body 1134 are disposed to the left of the drive shaft 1118 and the third valve body 1136 and the fourth valve body 1138 are disposed to the right of the drive shaft 1118. The valve 1100 also includes a first clutching structure, a second clutching structure, a third clutching structure, and a fourth clutching structure. As the drive shaft 1118 rotates, the first, second, third, and fourth valve bodies 1132, 1134, 1136, 1138 are selectively rotatable with the drive shaft 1118 via the first, second, third, and fourth clutch arrangements, respectively.
Fig. 12 is an exploded view of housing 1101 shown in fig. 11A. As shown in fig. 12, the housing 1101 includes a housing main body 1202 and a cover 1203. Cover 1203 is sized to match the size of orifice 1375 of conduit 1370 in housing body 1202 such that cover 1203 may be installed over orifice 1375 and block orifice 1375 such that housing 1101 cannot flow into or out of orifice 1375.
Fig. 13A is a perspective view of the housing main body 1202 shown in fig. 12, viewed from above, in front of the housing 1101; fig. 13B is a perspective view of the case main body 1202 shown in fig. 12, viewed from below and upward from behind the case 101. Fig. 13C and 13D are top and bottom views, respectively, of the housing body 1202 shown in fig. 12. FIG. 13E is a vertical downward cross-sectional view of the housing body 1202 shown in FIG. 12, taken along section line E-E in FIG. 13A, to illustrate further structural details inside the housing body 1202. To better describe the structure of the housing main body 1202, the extending direction of the first axis X, the second axis Y and the third axis Z is taken as a first direction, the horizontal line direction of the first axis X and the third axis Z is taken as a second direction, and the direction perpendicular to the first direction and the second direction is taken as a third direction.
As shown in fig. 13A-13E, the housing body 1202 has a top plate. The top panel includes a first transverse divider panel 1120, a second transverse divider panel 1323, and a vertical divider panel 1324. The first and second lateral partition plates 1120 and 1323 are disposed to have a step in the first direction to form a step 1301. First receiving chamber 1112 is disposed below first and second transverse partition plates 1120 and 1323, and second receiving chamber 1114 is disposed above first transverse partition plate 1120 such that the top of second receiving chamber 1114 is partially higher than the top of first receiving chamber 1112 in the first direction.
First transverse divider panel 1120 has perforations 1391 formed therein. A lower portion of the third valve body 1136 is capable of passing through the perforations 1391, thereby extending the lower portion of the third valve body 1136 into the first cavity 1112 and enabling the third valve body 1136 to rotate about the second axis Y.
First floor 1395 of first cavity 1112 has a concavity 1396 for receiving a lower portion of fourth valve body 1138. Since the upper portion of the fourth valve body 1138 is connected with the lower portion of the third valve body 1136, and the lower portion of the fourth valve body 1138 is received in the recessed portion 1396 of the first base plate 1395, the fourth valve body 1138 can be disposed in the first cavity 1112 and can rotate about the second axis Y.
Second transverse divider plate 1323 has a recessed portion 1393 for receiving an upper portion of first valve body 1132. The second floor 1397 of the first cavity 1112 has a concavity 1398 for receiving the lower portion of the second valve body 1134. Since the lower portion of the first valve body 1132 is sleeved with the upper portion of the second valve body 1134, the first valve body 1132 and the second valve body 1134 can be disposed in the first cavity 1112 together and can rotate around the first axis X.
The second transverse divider plate 1323 also has a recess 1394 for receiving an upper portion of the drive shaft 1118, thereby enabling the drive shaft 1118 to rotate about the third axis Z when the actuator drives the drive shaft 1118 to rotate.
Fig. 13F is a cross-sectional view of the housing body 1202 of fig. 12 taken parallel to section line F-F in fig. 13A to more clearly illustrate the shape of the first cavity 1112. As shown in fig. 13F, first receptacle 1112 is generally shaped as three intersecting cylinders, thereby forming a first cut cylindrical receptacle 1311, a second cut cylindrical receptacle 1312, and a third cut cylindrical receptacle 1313. First and second valve bodies 1132, 1134 are disposed in first and second cut cylindrical cavities 1311, 1312, and 1138 are disposed in third cut cylindrical cavity 1313. Wherein a central axis M of the first cut cylindrical receptacle 1311 coincides with the first axis X, a central axis N of the second cut cylindrical receptacle 1312 coincides with the third axis Z, and a central axis O of the third cut cylindrical receptacle 1313 coincides with the second axis Y.
As can be seen in fig. 13A-13E, a first set of housing openings is provided on the wall of the first cavity 1112, and the first set of housing openings includes a first housing opening 1361 arranged along the third direction and a second housing opening 1362 arranged oppositely along the third direction. The first and second housing openings 1361 and 1362 are provided at the same height in the first direction, and the first and second housing openings 1361 and 1362 are provided at heights that enable the first and second housing openings 1361 and 1362 to cooperate with the first valve body 1132. In other words, the first housing opening 1361 and/or the second housing opening 1362 can be selectively opened or closed as the first valve body 1132 rotates.
The first set of housing openings further includes a third housing opening 1363, the third housing opening 1363 is disposed within a range of angles opposite the second direction from the third direction, and is disposed at a lower height in the first direction than the first housing opening 1361 and the second housing opening 1362. The height of the third housing opening 1363 is set to enable the third housing opening 1363 to mate with the second valve body 1134. In other words, the third housing opening 1363 can be selectively communicated or disconnected when the second valve body 1134 is rotated.
The first set of housing openings further includes a fourth housing opening 1364, the fourth housing opening 1364 being disposed within a range of angles of reversal of the second direction from reversal of the third direction and being disposed slightly lower in the first direction than the third housing opening 1363. The fourth housing opening 1364 is disposed at a lower height than the second valve body 1134. In other words, the fourth housing opening 1364 is in fluid communication with the first cavity 1112 no matter what angle the second valve body 1134 is rotated to.
Wherein each of first housing opening 1361, second housing opening 1362, third housing opening 1363 and fourth housing opening 1364 is disposed around first tangential cylinder cavity 1311 with central axis M of first tangential cylinder cavity 1311 as the third direction.
The first set of housing openings further includes a fifth housing opening 1365 which is disposed within a range of angles opposite the third direction from the second direction and which is disposed at a height slightly lower than the second housing opening 1362 in the first direction. The height of the fifth housing opening 1365 is configured to enable the fifth housing opening 1365 to mate with the fourth valve body 1138. In other words, the fifth housing opening 1365 can be selectively opened or closed when the fourth valve body 1138 is rotated. Further, fifth housing opening 1365 is disposed in third tangential cylindrical cavity 1313 in a third direction about central axis O of third tangential cylindrical cavity 1313.
Each of the first, second, third, fourth, and fifth housing openings 1361, 1362, 1363, 1364, 1365 has a conduit disposed therearound and extending outwardly from the housing body 1202 such that each housing opening can be connected to other devices or conduits through the conduit.
FIG. 13G is a cross-sectional view of the housing body 1202 shown in FIG. 12, taken along section lines G-G in FIG. 13D, to illustrate a specific arrangement of the sixth housing opening 1366 and its conduits. As shown in fig. 13G, the first set of housing openings further includes a sixth housing opening 1366, the sixth housing opening 1366 being disposed at the intersection of the cavity wall of first cut cylindrical cavity 1311 and the cavity wall of second cut cylindrical cavity 1312. The sixth housing opening 1366 is disposed in a range of an angle opposite to the third direction from the second direction, and its set height in the first direction is slightly lower than the second housing opening 1362. The height of the sixth housing opening 1366 is set to enable the sixth housing opening 1366 to mate with the second valve body 1134. In other words, the sixth housing opening 1366 can be selectively opened or closed when the second valve body 1134 is rotated.
As seen in connection with fig. 12, conduit 1370 is disposed around sixth housing opening 1366 and extends outwardly from housing body 1202. The ports 1375 of the conduits 1370 are blocked by the cover 1203 so that fluid cannot flow from the ports 1375 into or out of the housing body 1202. Housing body 1202 also includes a conduit 1371 disposed perpendicular to conduit 1370. Conduit 1371 is in fluid communication with conduit 1370. Thus, fluid flowing from or into sixth housing opening 1366 into housing body 1202 can flow through orifice 1373,1374 of conduit 1371.
With continued reference to fig. 13A-13E, a second set of housing openings is provided in the walls of second receptacle 1114, including a seventh housing opening 1367 and an eighth housing opening 1368. The seventh housing opening 1367 is disposed within the range of the angle between the second direction and the third direction, and is disposed higher in the first direction than the fourth housing opening 1364. The eighth housing opening 1368 is disposed within a range of an angle between the reverse direction of the third direction and the second direction, and its set height in the first direction is slightly lower than the seventh housing opening 1367. The heights of seventh housing opening 1367 and eighth housing opening 1368 are configured to enable seventh housing opening 1367 and eighth housing opening 1368 to mate with third valve body 1136. In other words, the seventh housing opening 1367 and/or the eighth housing opening 1368 can be selectively connected or disconnected when the third valve body 1136 is rotated.
Each of the seventh housing opening 1367 and the eighth housing opening 1368 has a conduit disposed therearound and extending outwardly from the housing body 1202 such that the respective housing opening can be connected to other equipment or conduits through the conduit.
The second set of housing openings also includes a pump outlet housing opening 1369. A pump outlet housing opening 1369 is provided in the vertical divider plate 1324 for connection to a pump outlet (not shown). Specifically, the pump outlet housing opening 1369 is disposed within the range of angles between the reversal of the second direction and the reversal of the third direction, and the height of the pump outlet housing opening 1369 is set to enable the pump outlet housing opening 1369 to mate with the third valve body 1136. In other words, the pump outlet housing opening 1369 can be selectively communicated or disconnected as the third valve body 1136 is rotated.
As one example, the valve 1100 in the present application uses a pump (not shown) as the source of fluid flow. As shown in fig. 13A, the second transverse partition 1323 at the top of the first chamber 1112 has a plurality of through holes 1342 for connecting to the inlet of the pump. An opening 1399 at the top of second chamber 1114 can be capped by a pump. In this way, fluid in the first chamber 1112 can flow out of the housing 1101 through the plurality of holes 1242 into the pump, and subsequently fluid flowing out through the pump outlet can flow through the pump outlet housing opening 1369 into the second chamber 1114.
As one example, an actuator (not shown) is used herein as a power source for rotation of the drive shaft 1118. As shown in fig. 13B, the bottom of the first cavity 1112 has a circular hole 1303 for positioning an actuator. Through the holes 1303, the actuator can be coupled to the drive shaft 1118, thereby driving the drive shaft 1118 to rotate.
FIG. 14A is a perspective view of the drive shaft 1118 illustrated in FIG. 11B from a top view at an angle; fig. 14B is a perspective view of the drive shaft shown in fig. 11B from another angle, looking down and up. As shown in fig. 14A and 14B, the drive shaft 1118 includes a shaft 1401. The upper end 1410 of the shaft 1401 is designed to mate with a recess 1394 in the housing body 1202 so that the shaft 1401 can be rotatably connected with the housing 1101. The lower end 1412 of the shaft 1401 is designed to mate with the output end of the actuator so that the drive shaft 1118 can be driven to rotate when the actuator is operated.
The valve 1100 further includes a first clutchable drive structure 1402, a second clutchable drive structure 1403, and a third clutchable drive structure 1404 disposed on the shaft 1401. Specifically, a first clutchable drive structure 1402 is provided on the upper portion of the shaft 1401. The first clutchable drive structure 1402 includes a first transverse plate 1422 and a plurality of first bars 1424,1426,1428. The first lateral plate 1422 is substantially fan-shaped, and is laterally disposed on the upper portion of the shaft 1401 so that the circumferential direction of the fan-shape coincides with the circumferential direction of the shaft 1401. The center of the fan coincides with the axis of the axle 1401 so that when the drive shaft 1118 rotates about the first axis X, the first plurality of rods 1424,1426,1428 on the first cross plate 1422 also rotate about the first axis X. The plurality of first bars 1424,1426,1428 are provided uniformly in the vicinity of the outer edge of the first transverse plate 1422 in the circumferential direction of the first transverse plate 1422, and extend downward from the bottom surface of the first transverse plate 1422. The plurality of first rods 1424,1426,1428 are configured to cooperate with the first disengagable drive structure 1555 of the first valve body 1132, such that the first disengagable drive structure 1402 (i.e., at least one of the plurality of first rods 1424,1426,1428) of the drive shaft 1118 is configured to rotate the first valve body 1132 together when the drive shaft 1118 is rotated through a first angular range.
The second clutchable drive structure 1403 includes a second transverse arm 1432 and a second lever 1433. The second transverse arm 1432 is generally elongate and extends perpendicularly from the shaft 1401 in a radial direction of the shaft 1401, so that when the shaft 1401 is rotated, the distal end 1436 of the second transverse arm 1432 is also able to move circumferentially. The second lever 1433 is disposed at a distal end 1436 of the second transverse arm 1432 and extends upwardly from the upper surface of the second transverse arm 1432. The second lever 1433 is configured to cooperate with a second clutched driven structure 1755 on the second valve body 1134 such that the second clutched drive structure 1403 on the drive shaft 1118 (i.e., the second lever 1433) can rotate the second valve body 1134 together as the drive shaft 1118 rotates through a second range of angles.
The third clutchable drive structure 1404 includes a third transverse arm 1442 and a third lever 1443. The third transverse arm 1442 is substantially elongated and extends perpendicularly from the upper portion of the shaft 1401 in the radial direction of the shaft 1401, so that when the shaft 1401 is rotated, the distal end 1446 of the third transverse arm 1442 is also capable of circular movement. The third lever 1443 is disposed at a distal end 1446 of the third transverse arm 1442 and extends downward from a lower surface of the third transverse arm 1442. The third rod 1443 is configured to cooperate with a third clutchable driven structure 1955 on the third valve body 1136 and a fourth clutchable driven structure 2155 on the fourth valve body 1138 such that the third clutchable driving structure 1404 (i.e., the third rod 1443) on the drive shaft 1118 is able to rotate the third valve body 1136 when the drive shaft 1118 is rotated within a third angular range; and the third clutchable drive structure 1404 (i.e., the third lever 1443) on the drive shaft 1118 is able to rotate the fourth valve body 1138 as the drive shaft 1118 rotates through the fourth angular range.
Fig. 15A is a perspective view of the first valve body 1132 shown in fig. 11B, viewed from above; fig. 15B is a perspective view of the first valve body 1132 shown in fig. 11B, viewed from below.

The lower portion of the shaft 1162 is provided with a recess 1552 to form a sleeve 1155. The sleeve 1155 is configured to receive the upper end of the shaft 1164 of the second valve body 1134, thereby enabling the first valve body 1132 and the second valve body 1134 to rotate about the same first axis X. Upper portion 1402 of first valve body 1132 is designed to mate with recessed portion 1393 of second transverse divider plate 1323, thereby enabling upper portion 1402 of first valve body 1132 to be received by recessed portion 1393.
The first valve body 1132 is provided with a first disengageable driven structure 1555 on a ball thereof, the first disengageable driven structure 1555 includes a plurality of first grooves 1512,1513,1514,1515,1516,1517, a plurality of first grooves 1512,1513,1514,1515,1516,1517 are provided on an upper surface of the ball of the first valve body 1132 and are arranged in a circumferential direction of the first valve body 1132, and in particular, the plurality of first grooves 1512,1513,1514,1515,1516,1517 are formed by being grooved from an edge of the ball of the first valve body 1132 toward an inside of the ball, and a distribution of the plurality of first grooves 1512,1513,1514,1515,1516,1517 on the ball of the first valve body 1132 forms a central angle of β.
Two valve body opening portions 1562,1564 are provided on the first valve body 1132, and two valve body opening portions 1562,1564 are configured such that when the first valve body 1132 is rotated, at least one of the two valve body opening portions 1562,1564 can be selectively aligned with the first housing opening 1361 and/or the second housing opening 1362 in the wall of the first volume 1112 to allow communication and disconnection of the first housing opening 1361 and the second housing opening 1362, respectively.
Fig. 16 is a schematic illustration of the mating relationship of the first valve body 1132 with the drive shaft 1118 to illustratively show one of the states of engagement of the first clutched drive structure 1402 with the first clutched driven structure 1555. As shown in fig. 16, at least one of the first plurality of bars 1424,1426,1428 on the drive shaft 1118 is engageable with at least one of the first plurality of slots 1512,1513,1514,1515,1516,1517 when the drive shaft 1118 rotates within a first angular range. Thus, the drive shaft 1118 can rotate the first valve element 1132.
It should be noted that although the first valve body 1132 is sleeved on the second valve body 1134, because a friction force exists between the first valve body 1132 and the second valve body 1134, the second valve body 1134 does not rotate along with the first valve body 1132 when the first valve body 1132 rotates.
FIG. 17A is a top-down perspective view of the second valve body 1134 shown in FIG. 11B; fig. 17B is a perspective view of the second valve body 1134 shown in fig. 11B, as viewed from below. As shown in fig. 17A and 17B, the second valve body 1134 includes a second valve body 1733 and a shaft 1164. The top of the shaft 1164 is stepped and is received by a sleeve 1155 at the lower portion of the first valve body 1132, so that the first valve body 1132 and the second valve body 1134 can rotate around the same first axis X.
The second valve body 1733 is a substantially spherical shell cut vertically, and the second valve body 1733 is disposed around the rotating shaft 1164. The lower portion of the second valve body 1733 is fixedly connected to the shaft 1164 through a plurality of connecting posts 1704,1706,1708. The second valve body 1733 is provided with a valve body opening portion 1762, the valve body opening portion 1762 being configured such that when the second valve body 1134 is rotated, the valve body opening portion 1762 can be selectively aligned with the third housing opening 1363 and/or the sixth housing opening 1366 in the cavity wall of the first cavity 1112, thereby enabling communication and disconnection of the third housing opening 1363 and the sixth housing opening 1366.
The lower portion of the shaft 1164 is provided with a second clutched driven structure 1755. The second clutched driven structure 1755 includes a second valve body plate 1712.

As shown in fig. 18, when the drive shaft 1118 rotates within a second angular range, a second rod 1433 on the drive shaft 1118 engages the second slot 1722. Thus, the drive shaft 1118 is able to rotate the second valve body 1134 within a second angular range.
It should be noted that although the first valve body 1132 is sleeved on the second valve body 1134, because a friction force exists between the first valve body 1132 and the second valve body 1134, when the second valve body 1134 rotates, the first valve body 1132 does not rotate along with the rotation of the second valve body 1134.
FIG. 19A is a perspective view of the third valve body 1136 shown in FIG. 11B, from a top view; fig. 19B is a perspective view of the third valve body 1136 shown in fig. 11B, viewed from another angle, from below to above.

The top of shaft 1166 is received by a coupling on the pump and the lower portion of shaft 1166 is provided with a recess 1902 to form sleeve 1156. The sleeve 1156 is configured to receive the upper end of the shaft 1168 of the fourth valve body 1138, thereby enabling the third valve body 1136 and the fourth valve body 1138 to rotate about the same second axis Y.
Third valve body 1933 is generally spherical shell shaped and is disposed about spindle 1166. The lower portion of the third valve body 1933 is fixedly connected to the rotating shaft 1166 via the connecting plate 1904. Two valve body opening portions 1962,1964 are provided on third valve body 1933, two valve body opening portions 1962,1964 are configured such that when third valve body 1136 is rotated, at least one of the two valve body opening portions 1962,1964 can be selectively aligned with pump outlet housing opening 1369, seventh housing opening 1367 and/or eighth housing opening 1368 in the chamber wall of second volume 1114, thereby enabling the flow of pump outlet housing opening 1369, seventh housing opening 1367 and eighth housing opening 1368 to be disconnected.
A third disengagable driven structure 1955 is disposed on a lower portion of the shaft 1166. The third clutchable driven structure 1955 includes a third valve plate 1912. One end of the third valve plate 1912 is connected to a lower portion of the rotating shaft 1166, and the other end of the third valve plate 1912 is provided with a third slot 1922, and the third slot 1922 is arranged in a radial direction of the third valve body 1136. When the drive shaft 1118 rotates within the third angular range, the third rod 1443 on the drive shaft 1118 is able to engage the third slot 1922 on the third valve body 1136.
FIG. 20 is a schematic illustration of the mating relationship of the third valve body 1136 with the drive shaft 1118 to schematically illustrate one of the states of engagement of the third clutched drive structure 1404 and the third clutched driven structure 1955. As shown in FIG. 20, when the drive shaft 1118 rotates within a third angular range, the third rod 1443 on the drive shaft 1118 engages the third slot 1922 on the third valve body 1136. The drive shaft 1118 is thereby able to rotate the third valve body 1136 within a third angular range.
It should be noted that although the third valve body 1136 is sleeved on the fourth valve body 1138, since there is friction between the third valve body 1136 and the fourth valve body 1138, when the third valve body 1136 rotates, the fourth valve body 1138 does not rotate along with the rotation of the second valve body 1134.
FIG. 21A is a perspective view of the fourth valve body 1138 shown in FIG. 11B from a top view from an angle; fig. 21B is a perspective view of the fourth valve body 1138 shown in fig. 11B, viewed from another angle, from below. As shown in fig. 21A and 21B, the fourth valve body 1138 includes a fourth valve body 2133 and a rotating shaft 1168. The top of the shaft 1166 is stepped and is received by a sleeve 1156 at the lower portion of the third valve body 1136, thereby allowing the third valve body 1136 and the fourth valve body 1138 to rotate about the same second axis Y.
The fourth valve body 2133 is substantially spherical shell-shaped and is disposed around the rotating shaft 1168. The upper part and the lower part of the fourth valve body 2133 are respectively provided with a connecting plate 2104,2105 fixedly connected with the rotating shaft 1168. The fourth valve body 2133 is provided with three valve body opening portions 2162,2164,2166, 2162,2164,2166 being configured such that when the fourth valve body 1138 is rotated, at least one of the three valve body opening portions 2162,2164,2166 is selectively alignable with the fourth housing opening 1364 in the wall of the first volume 1112 to effect flow communication and disconnection of the fourth housing opening 1364.
A fourth clutchable driven structure 2155 is provided on the upper portion of the shaft 1168. The fourth clutched driven structure 2155 includes a fourth valve body plate 2112. One end of the fourth valve body plate 2112 is connected to the upper portion of the rotation shaft 1168, and the other end of the fourth valve body plate 2112 is provided with a fourth groove 2122, the fourth groove 2122 being arranged in the radial direction of the fourth valve body 1138. When the drive shaft 1118 rotates through a fourth angular range, the third rod 1443 on the drive shaft 1118 is able to engage the fourth groove 2122 on the fourth valve body 1138.
Fig. 22 is a schematic illustration of the mating relationship of the fourth valve body 1138 with the drive shaft 1118 to schematically illustrate one of the states in which the third clutched drive structure 1404 is engaged with the fourth clutched driven structure 2155. As shown in FIG. 22, the third rod 1443 on the drive shaft 1118 engages the fourth slot 2122 when the drive shaft 1118 rotates through a fourth angular range. The drive shaft 1118 is thereby able to rotate the fourth valve body 1138 through a fourth angular range.
It should be noted that although the fourth valve body 1138 is sleeved on the fourth valve body 1138, since there is friction between the third valve body 1136 and the fourth valve body 1138, when the fourth valve body 1138 rotates, the third valve body 1136 does not rotate along with the rotation of the fourth valve body 1138.
It should also be noted that in the embodiments of the present application, the third clutchable driven structure 1955 and the fourth clutchable driven structure 2155 cooperate with the third clutchable driving structure 1404, respectively, to form a third clutching structure and a fourth clutching structure. However, since the groove walls of the third groove 1922 at both sides are different in length from the groove walls of the fourth groove 2122 at both ends, the engagement and disengagement times of the third clutch structure and the fourth clutch structure are different. In an embodiment of the present application, the third clutch structure may be engaged when the drive shaft 1118 rotates within the third angular range, and the fourth clutch structure may be engaged when the drive shaft 1118 rotates within the fourth angular range.
Since the first clutch structure, the second clutch structure, the third clutch structure and the fourth clutch structure in the present application are generally all engaged and disengaged in a way of using a groove and a rod, in order to clearly illustrate the specific matching relationship among the clutch structures, the third clutch structure is taken as an example in the present application and is explained in detail.
23A-23H are schematic diagrams of the third clutching structure during operation to illustrate how the third clutching structure achieves engagement and disengagement. In particular, the third clutching structure includes a third clutchable drive structure 1404 and a third clutchable driven structure 1955, the third clutchable drive structure 1404 being engageable with the third clutchable driven structure 1955 to rotate the third clutchable driven structure 1955 together when the drive shaft 118 rotates within a third angular range; when the drive shaft 1118 rotates outside of the third angular range, the third clutchable drive structure 1404 is disengaged from the third clutchable driven structure 1955 so as not to rotate the third clutchable driven structure 1955. The relative positional relationship of the axle 1401, third transverse arm 1442 and third lever 1443 of the drive shaft 1118 is schematically illustrated in fig. 23A-23H. As the drive shaft 1118 rotates, the axle 1401, the third lateral arm 1442, and the third rod 1443 rotate together about the third axis Z. Fig. 23A to 23H also schematically show the relative positional relationship of the rotating shaft 1166 of the third valve body 1136, the third valve body plate 1912, and the third slot 1922. When the third valve body 1136 rotates, the rotating shaft 1166, the third valve plate 1912 and the third slot 1922 rotate together about the second axis Y.
Fig. 23A illustrates the relative positional relationship of the third clutched drive structure 1404 and the third clutched driven structure 1955 when the drive shaft 1118 has not yet rotated to the initial angle of the third angular range. Specifically, the actuator rotates the drive shaft 1118 in a counterclockwise direction (e.g., in the direction of arrow T in fig. 23A), and thus the third clutchable drive structure 1404 also rotates in a counterclockwise direction. While the third disengagable driven structure 1955 remains in the first position because it is not being driven by the actuator.
Fig. 23B illustrates the relative positional relationship of the third clutched drive structure 1404 and the third clutched driven structure 1955 when the drive shaft 1118 is rotated to a first boundary angle of a third angular range. Specifically, when the drive shaft 1118 rotates in the counterclockwise direction to the initial angle of the third angular range, the third rod 1443 of the drive shaft 1118 contacts the first sidewall 2302 of the third slot 1922 and thus the third rod 1443 is received in the third slot 1922.
Fig. 23C illustrates the relative positional relationship of the third clutched drive structure 1404 and the third clutched driven structure 1955 when the drive shaft 1118 is rotating counterclockwise within a third angular range. Specifically, as the drive shaft 1118 continues to rotate in the counterclockwise direction, the third rod 1443 pushes against the first side wall 2302 of the third slot 1922, thereby rotating the third valve plate 1912. Thus, the third disengagable drive structure 1404 causes the third disengagable driven structure 1955 to rotate in a clockwise direction (e.g., as indicated by arrow U in fig. 23C).
Fig. 23D illustrates the third clutched drive structure 1404 disengaged from the third clutched driven structure 1955 when the drive shaft 1118 rotates to a second boundary angle of the third angular range. Fig. 23E illustrates the third clutched drive structure 1404 disengaged from the third clutched driven structure 1955 when the drive shaft 1118 rotates outside of the third angular range. Specifically, as the drive shaft 1118 continues to rotate in the counterclockwise direction, the third rod 1443 disengages from the third slot 1922, thereby allowing the drive shaft 1118 to continue to rotate in the counterclockwise direction while the third clutched driven structure 1955 remains in the second position. That is, the third disengagable driving structure 1404 cannot rotate the third disengagable driven structure 1955.
Fig. 23F illustrates the relative positional relationship of the third clutched drive structure 1404 and the third clutched driven structure 1955 when the drive shaft 1118 is rotated to a second boundary angle of the third angular range. Specifically, when the drive shaft 1118 rotates in a clockwise direction (e.g., as indicated by arrow P in fig. 23F), the third clutchable drive structure 1404 also rotates in a clockwise direction. The third rod 1443 of the drive shaft 1118 contacts the second side wall 2304 of the third slot 1922, and thus the third rod 1443 is received in the third slot 1922.
Fig. 23G illustrates the relative positional relationship of the third clutched drive structure 1404 and the third clutched driven structure 1955 when the drive shaft 1118 is rotating clockwise within a third angular range. Specifically, as the drive shaft 1118 continues to rotate in the clockwise direction, the third rod 1443 pushes against the second side wall 2304 of the third slot 1922, thereby rotating the third valve plate 1912. Thus, the third disengagable driving structure 1404 causes the third disengagable driven structure 1955 to rotate in a counter-clockwise direction (e.g., in the direction of arrow V in fig. 23G).
Fig. 23H illustrates the third clutched drive structure 1404 disengaged from the third clutched driven structure 1955 when the drive shaft 1118 is rotated to the first boundary angle of the third angular range. Specifically, as the drive shaft 1118 continues to rotate in the clockwise direction, the third rod 1443 disengages from the third slot 1922, thereby allowing the drive shaft 1118 to continue to rotate in the clockwise and counterclockwise directions while the third clutched driven structure 1955 remains in the first position. That is, the third disengagable driving structure 1404 cannot rotate the third disengagable driven structure 1955.
It is noted that the angle at which rotation of the third clutched drive structure 1404 can engage the third clutched driven structure 1955 to rotate the third clutched driven structure 1955 is referred to as a third angular range.
With continued reference to fig. 14A-14B, it can be seen that the first, second and third clutchable drive structures 1402, 1403, 1404 disposed on the shaft 1401 are disposed in different angular orientations of the shaft 1401. Such an arrangement may enable a clutchable drive feature on the shaft 1401 to selectively engage a clutchable driven feature on the valve body to drive rotation of different valve bodies when the shaft 1401 is rotated through different angles.
In the present application, the specific structures and positional relationships of the first valve body 1132, the second valve body 1134, the third valve body 1136, and the fourth valve body 1138 and the first clutch structure, the second clutch structure, the third clutch structure, and the fourth clutch structure are configured to be able to realize: the valve body opening portion on the first valve body 1132 is configured to cooperate with the first and second housing openings 1361, 1362 such that the valve body opening portion on the first valve body 1132 is configured to selectively open at least one of the first and second housing openings 1361, 1362; a valve body opening portion on the second valve body 1134 is configured to mate with the third housing opening 1363 and the sixth housing opening 1366 such that the valve body opening portion on the second valve body 1134 is configured to selectively open at least one of the third housing opening 1363 and the sixth housing opening 1366; a valve body opening portion on third valve body 1136 is configured to cooperate with seventh housing opening 1367 and eighth housing opening 1368 such that the valve body opening portion on third valve body 1136 is configured to selectively open at least one of seventh housing opening 1367 and eighth housing opening 1368; a valve body opening portion on the fourth valve body 1138 is configured to mate with the fifth housing opening 1365 such that the valve body opening portion on the fourth valve body 1138 is configured to selectively open the fifth housing opening 1365.
As the drive shaft 1118 rotates, one or more of the first valve body 1132, the second valve body 1134, the third valve body 1136, and the fourth valve body 1138 are selectively rotated to create different fluid passages within the interior of the valve 1100. As one example, valve 1100 is capable of achieving a variety of communication relationships as shown in Table 1.
Figure BDA0002359801980000311
TABLE 1
The left hand indices 1-10 in Table 1 indicate different degrees of rotation of the drive shaft 1118, e.g., index 1 indicates that the drive shaft 1118 is rotating at a first angle. It should be noted that, as an example, reference numerals 1-10 indicate the angles at which the drive shaft 1118 is rotated in the same direction from an initial angle. It is further noted that the drive shaft 1118 is configured to rotate in both directions (i.e., clockwise rotation and counterclockwise rotation).
The symbol "O" in Table 1 indicates that the communication port is in a fully communicated state, i.e., the housing opening in the housing is aligned with the opening in the valve body, thereby allowing fluid to flow through the full area of the housing opening in the housing, the symbol "R" in Table 1 indicates that the communication port is in a partially communicated state, i.e., the housing opening in the housing is partially aligned with the opening in the valve body, thereby allowing fluid to flow only partially through the portion of the housing opening that is aligned with the valve body opening, the symbol "×" in Table 1 indicates that the housing opening is in a broken state, i.e., the housing opening is blocked by the valve body, thereby preventing fluid from flowing through the housing opening.
By controlling the opening and closing states of the respective housing openings and the mutual cooperation between the respective valve bodies, a plurality of fluid passages, each for communicating with the respective two housing openings, can be formed in the valve 1100, so that the external piping connected to the two respective housing openings can be communicated through the fluid passages. The several fluid passages in the valve 1100 can be switched on or off by controlling the rotation of the respective valve bodies. For example, if the fourth housing opening 1364 listed in Table 1 is used as the fluid inlet for valve 1100 and the remaining seven housing openings are used as the fluid outlets for valve 1100, then there are seven fluid passages in valve 1100, including fluid passage 1, fluid passage 2, fluid passage 3, fluid passage 5, fluid passage 6, fluid passage 7, and fluid passage 8. Wherein fluid passageway 1 communicates between fourth housing opening 1364 and first housing opening 1361, fluid passageway 2 communicates between fourth housing opening 1364 and second housing opening 1362, fluid passageway 3 communicates between fourth housing opening 1364 and third housing opening 1363, fluid passageway 5 communicates between fourth housing opening 1364 and fifth housing opening 1365, fluid passageway 6 communicates between fourth housing opening 1364 and sixth housing opening 1366, fluid passageway 7 communicates between fourth housing opening 1364 and seventh housing opening 1367, and fluid passageway 8 communicates between fourth housing opening 1364 and eighth housing opening 1368.
When the valve 1100 is at the first angle, the valve body opening portion on the first valve body 1132 is aligned with the fourth housing opening 1364 such that the first housing opening 151 is opened; the valve body opening portion on the first valve body 1132 is aligned with the second housing opening 1362 such that the second housing opening 1362 is opened; the valve body opening portion on the second valve body 1134 is aligned with the third housing opening 1363 such that the third housing opening 1363 is opened; the valve body opening portion on the fourth valve body 1138 is aligned with the fifth housing opening 1365 such that the fifth housing opening 1365 is opened; the valve body opening portion on the third valve body 1136 is aligned with the seventh housing opening 1367 such that the seventh housing opening 1367 is opened; the valve body opening portion on third valve body 1136 is aligned with eighth housing opening 1368 such that eighth housing opening 1368 is opened; and the valve body opening portion on the second valve body 1134 is not aligned with the sixth housing opening 1366 such that the sixth housing opening 1366 is closed or blocked. At this time, the fluid passage 1 communicating the fourth housing opening 1364 and the first housing opening 1361 is turned on, the fluid passage 2 communicating the fourth housing opening 1364 and the second housing opening 1362 is turned on, the fluid passage 3 communicating the fourth housing opening 1364 and the third housing opening 1363 is turned on, the fluid passage 5 communicating the fourth housing opening 1364 and the fifth housing opening 1365 is turned on, the fluid passage 7 communicating the fourth housing opening 1364 and the seventh housing opening 1367 is turned on, the fluid passage 8 communicating the fourth housing opening 1364 and the eighth housing opening 1368 is turned on, and the fluid passage 6 communicating the fourth housing opening 1364 and the sixth housing opening 1366 is turned off.
When the valve 1100 is at the second angle, the valve body opening portion on the first valve body 1132 is aligned with the fourth housing opening 1364 such that the first housing opening 151 is opened; the valve body opening portion on the first valve body 1132 is aligned with the second housing opening 1362 such that the second housing opening 1362 is opened; the valve body opening portion on the second valve body 1134 is aligned with the third housing opening 1363 such that the third housing opening 1363 is opened; the valve body opening portion on the fourth valve body 1138 is aligned with the fifth housing opening 1365 such that the fifth housing opening 1365 is opened; the valve body opening portion on the second valve body 1134 is aligned with the sixth housing opening 1366 such that the sixth housing opening 1366 is opened; the valve body opening portion on the third valve body 1136 is aligned with the seventh housing opening 1367 such that the seventh housing opening 1367 is opened; the valve body opening portion on third valve body 1136 is aligned with eighth housing opening 1368 such that eighth housing opening 1368 is opened. At this time, the fluid passage 1 communicating the fourth housing opening 1364 and the first housing opening 1361 is communicated, the fluid passage 2 communicating the fourth housing opening 1364 and the second housing opening 1362 is communicated, the fluid passage 3 communicating the fourth housing opening 1364 and the third housing opening 1363 is communicated, the fluid passage 5 communicating the fourth housing opening 1364 and the fifth housing opening 1365 is communicated, the fluid passage 6 communicating the fourth housing opening 1364 and the sixth housing opening 1366 is communicated, the fluid passage 7 communicating the fourth housing opening 1364 and the seventh housing opening 1367 is communicated, and the fluid passage 8 communicating the fourth housing opening 1364 and the eighth housing opening 1368 is communicated.
Similarly, the on and off states of the various fluid passages in the valve 1100 at the third through tenth angles may be found in accordance with Table 1.
It should be noted that the valve 1100 of the embodiment shown in fig. 11A-24 is not limited to the above-described application. According to the requirement of the cooling path of the cooling system, various fluid passages can be formed in the valve 1100 by arranging a power device such as a pump, so that the purpose of switching the cooling path can be achieved by using the valve 1100 as a switching device of the cooling path.
Although the clutch structure is described herein with a slot and a rod as an example, those skilled in the art will appreciate that other engagement means (e.g., clasping means, gear engagement) for achieving such clutching and declutching are within the scope of the present application.
The valve 1100 of the present application can realize the switching of channels with different fluids by the arrangement of the opening on the valve body and the opening on the housing, and can also control the flow rate of each channel. The arrangement can enable the control assembly in the system to control fewer elements to realize the switching of channels with different fluids, and can enhance the stability of system control while integrating control.
To ensure sealing between the housing opening and the valve body when each housing opening in the valve 1100 is not aligned with an opening on the valve body (i.e., the housing opening is closed), the valve 1100 also includes a first set of seals and a second set of seals. Each of the first set of seals is disposed between the first, second, and fourth valve bodies 1132, 1134, 1138 and each of the first set of housing openings. Each of the first set of seals is configured to abut against a wall of the cavity in which each of the first set of housing openings is located such that the first set of seals can abut against the wall of the cavity when the valve body is rotated without rotating with the rotation of the valve body. The second set of seals includes two seals, one of which is disposed between seventh housing opening 1367 and third valve body 1136 and the other of which is disposed between eighth housing opening 1368 and third valve body 1136. Since the pump outlet housing opening 1369 of the second set of housing openings is connected to the outlet of the pump, no seal is provided.
When the valve body rotates, the friction exists between the valve body and the sealing piece, so that the actuator driving the valve body to rotate needs larger driving force, and the valve body is driven to rotate so as to overcome the friction force between the valve body and the sealing piece. When a conventional valve drives one or more valve bodies to rotate, the driving shaft of the valve needs to overcome the friction force caused by all sealing elements arranged in the valve bodies, so that the required power of an actuator is larger.
The valve 1100 in the present application also has the following advantages: when the passage of the valve 1100 requiring flow is realized by the rotation of the valve body on one side of the driving shaft 1118, the valve body on the other side does not rotate, so that no friction is generated between the non-rotating valve body and the sealing member, and thus the driving force provided by the actuator is reduced, and only the friction force to be overcome by the valve body requiring rotation of the driving shaft 1118 needs to be provided. The states of the valve bodies in valve 1100 at numbers 8-10 in table 1 are described below as examples.
Fig. 24 is a schematic view of the valve 1100 shown in fig. 11A cut in a horizontal direction to the first and second housing openings 1361, 1362, and fig. 24 shows the first seal 2402 disposed between the first valve body 1132 and the first housing opening 1361, the second seal 2404 disposed between the first valve body 1132 and the second housing opening 1362, and the third seal 2406 disposed between the fourth valve body 1138 and the fifth housing opening 1365. When the drive shaft 1118 is rotated through the angular range shown by reference numerals 8-10, only the first valve body 1132 and the second valve body 1134 need to be rotated, and thus the actuator that drives the drive shaft 1118 to rotate need only provide a frictional force that overcomes the seals on the first valve body 1132 and the second valve body 1134.
It should be noted that in each of the embodiments shown in fig. 1A-24, the valve body opening portion of each valve body forms a valve body engagement portion for interacting with a corresponding one of the plurality of housing openings to selectively communicate at least one fluid passage when the driven valve body member is rotated a predetermined angle. In yet other embodiments, the valve body actuation portion may be a valve body blocking portion for interacting with at least one of the plurality of housing openings when the driven valve body member is rotated a predetermined angle such that the valve body blocking portion selectively blocks the at least one of the plurality of housing openings to selectively block the at least one fluid passageway. The following is described with reference to FIGS. 25A-25C as an example:
FIG. 25A is a schematic side perspective structural view of a ninth embodiment of a valve according to the present application; fig. 25B is a cross-sectional view of the valve 2500 of fig. 25A taken along the line H-H of fig. 25A, and fig. 25C is a cross-sectional view of the valve 2500 of fig. 25A taken along the line I-I of fig. 25A to illustrate another embodiment of the service portion of the valve body member. As shown in fig. 25A-25C, the valve 2500 includes a housing 2501. Housing 2501 is generally cylindrical and has a housing receptacle 2502 therein. Four housing openings, namely a first housing opening 2551, a second housing opening 2552, a third housing opening 2553 and a fourth housing opening 2554, are provided on the housing 2501. Housing volume 2502 can be in fluid communication with the environment of valve 2500 through any one of first housing opening 2551, second housing opening 2552, third housing opening 2553 and fourth housing opening 2554. Wherein the first and second case openings 2551 and 2552 are disposed at the same height on the left and right sides of the case 2501, and the third and fourth case openings 2553 and 2554 are disposed at the same height on the front and rear sides of the case 2501 with respect to the case 2501.
The valve 2500 also includes a drive 2580. The drive device 2580 includes an actuator 2590 and a drive shaft 2518. The actuator 2590 is disposed outside the housing 2501. The drive shaft 2518 is disposed in the housing 2501 in the height direction and is connected to the actuator 2590. The actuator 2590 is configured to drive the rotation of the drive shaft 118.
The valve 2500 also includes a first valve body 121 and a second valve body 122. The first valve body 121 is disposed at substantially the same height as the first and second housing openings 151 and 152, and the second valve body 122 is disposed at substantially the same height as the third and fourth housing openings 153 and 154. The first valve body 121 and the second valve body 122 are generally rectangular bodies with a recessed waist such that a clearance volume 2588 is formed between the first valve body 121 and the housing 2501 and a clearance volume 2589 is formed between the second valve body 122 and the housing 2501.
The valve 2500 also includes a seal 2571,2572,2573,2574. Seals 2571,2572,2573,2574 are respectively disposed within housing 2501 and respectively disposed about housing opening 2551,2552,2553,2554 for sealing a gap between a respective one of the plurality of housing openings 2551,2552,2553,2554 and the plurality of valve bodies 2521,2522,2523,2524.
The valve 2500 also includes a first clutching structure 2541 and a second clutching structure 2542. The first clutching structure 2541 includes a first clutchable drive structure 2581 and a first clutchable driven structure 2591. A first clutchable drive structure 2581 is provided on the drive shaft 2518. A first clutchable driven structure 2591 is provided on the first valve body 2521. The first clutched drive structure 2581 and the first clutched driven structure 2591 are configured to cooperate with one another such that, when the drive shaft 2518 is rotated within a first angular range, the first clutched drive structure 2581 on the drive shaft 2518 is able to rotate the first valve body 2521. The second clutching structure 142 includes a second clutchable drive structure 2582 and a second clutched driven structure 2592. A second clutchable drive structure 2582 is provided on the drive shaft 2518. A second clutchable driven structure 2592 is provided on the second valve body 2522. The second clutched drive structure 2582 and the second clutched driven structure 2592 are configured to cooperate such that the second clutched drive structure 2582 on the drive shaft 2518 can rotate the second valve body 2522 when the drive shaft 2518 rotates within the second angular range.
As one example, the clutching structure in fig. 25A-25C is a clasping device. A clutchable driven structure is disposed about the clutchable driving structure. When the clutchable driven structure holds the clutchable driving structure tightly, the clutchable driving structure can drive the clutchable driven structure to rotate. When the clutchable driven structure does not tightly hold the clutchable driving structure, the clutchable driving structure cannot drive the clutchable driven structure to rotate.
Fig. 25B shows a state in which the first clutchable driven structure 2591 clasps the first clutchable driving structure 2581. First valve body 2521 now blocks first housing opening 2551 and second housing opening 2552 such that first housing opening 2551 and second housing opening 2552 are not in fluid communication with housing plenum 2502. In other words, the first housing opening 2551 and the second housing opening 2552 are disconnected.
Fig. 25C shows a state in which the second disengagable driven structure 2592 does not hug the second disengagable driving structure 2582. At this time, the second valve body 2522 does not block the third and fourth case openings 2553 and 2554. Third housing opening 2553 and fourth housing opening 2554 can communicate with one another through clearance volume 2589 (i.e., bypassing second valve body 2522).
It can be seen that in the valve 2500 shown in fig. 25A-25C, the active portion of the valve body member is the valve body itself (i.e., the valve body clogging portion). When the blocking portion of the valve body is mated with the housing opening, the valve body member can block the housing opening, thereby interrupting the fluid passage and allowing a fluid passage to be formed between the housing openings that are not blocked by the blocking portion of the valve body.
It should be noted that the embodiment shown in fig. 1A-10 can also employ the valve body blocking portion shown in fig. 25A-25C to effect opening and blocking of the housing opening to selectively open or close at least one of the plurality of fluid passages in the valve by the actuated valve body.
While only certain features of the application have been illustrated and described herein, many modifications and changes will occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the application.
