ROTATING DEVICE BACKGROUND OF THE INVENTION The present invention relates to a novel and improved rotating device, such as a pump or motor, for use with fluids. A pump or motor can be mounted in many different orientations on a support structure. For example, steering power pumps in different types of vehicles can be mounted in different orientations-depending on the space available within a motor vehicle. In addition, the conduits for driving the fluid to the steering power pumps in different vehicles can be connected are different portions of the driving power pump. Since steering power pumps can be mounted in different orientations on different vehicles, the manufacture of the steering power pumps is simplified provided that the same components can be used for the steering power pumps that are mounted on the different orientations In addition, the repair and maintenance of steering power pumps in different vehicles is simplified as long as the steering power pumps in the different vehicles have the same components.
BRIEF DESCRIPTION OF THE INVENTION The present invention provides a new and improved rotating device, such as a motor or pump for fluids. The rotating device can be mounted in many different orientations in a support structure. In addition, a fluid condusto with a plurality of different portions of the rotating device can be connected to facilitate the assembly of the rotating device in the different orientations on a support structure. The rotating device includes a housing having a main section and a cover section, which encloses the components of the rotating device. The main section and the. of the cover are movable with respect to each other of any orientation of the plurality of orientations that allow the rotary device to be mounted in different orientations on different support structures. A main section of the housing has a plurality of ascending or vertical tubes. Each of the vertical tubes has a surface that defines a location that can be connected to a fluid conduit. Depending on the desired orientation of the fluid conduit relative to the main section of the housing, one of the plurality of connection locations is selected. At the selected connection location, the housing is machined to form a portion of a connection for the fluid conduit and to form passages in the housing. The other connection locations, which are not selected, are left intact. During the use of the rotating device, the fluid tends to leak along a drive shaft in a seal. Fluid leaking along the drive shaft in the seal is conducted away from the seal through a drain passage in the cover section of the housing and a drain passage in the main section of the housing. The seal drain passages in the cover section and in the main section of the housing are interconnected through an annular multiple chamber disposed between the main section and housing cover. The annular manifold chamber allows the cover section and the main section of the housing to move relative to each other to provide a selected orientation of the main section of the rotating device relative to the cover section.

DESCRIPTION OF A SPECIFIC PREFERRED MODALITY OF THE INVENTION A rotating device 20 (Figure 1) with a fluid is used. Although the rotary device 20 can be any of a pump or a motor, in the illustrated embodiment of the invention, the rotary device 20 is a hydraulic pump suitable for use as a steering power pump in a vehicle. However, it will be understood that the rotary device 20 can be used as a hydraulic pump in other locations. It will also be understood that the rotary device 20 can be used as a hydraulic motor. The pump 20 includes a work or service unit 22 which is enclosed by a housing 24. The housing 24 includes a main section 26 and a cover section 28. The cover section 28 is telescopically coupled with the main section 26. in a joint 30. The main section 26 is a one piece metallic casting. Similarly, the cover section 28 is a one-piece metallic casting. The main section 26 is connected to the cover 28 by retaining bolts 32 (Figure 3). Although only two retaining bolts 32 have been shown in Figure 3, it will be understood that there are four, relatively long, retaining bolts extending from the rear of the main section 26 of the housing 24 in the threaded openings in the cover section 28 of the pump 20. A mounting flange 34 in the cover section 28 is used to connect the pump 20 with a suitable support structure. The work unit 22 (Figure 1) is enclosed by the housing 24. The work unit 22 includes a cylindrical disk or cam ring 38, which extends around a rotor 40. A plurality of vanes 42 extend between the cam ring 38 and rotor 40. A drive belt 44 is connected to the rotor 40 and is rotatable to rotate the rotor and the vanes or vanes 42 relative to the cam ring 38. A lower or end plate of wear 48 connects to cover section 28 and engages the rail ends (as seen in Figure 1) of rotor 40 and cam ring 38. A top or snap end plate 50 engages the ends axially opposite of the cam ring 38 and the rotor 40. The cam ring 38, the wear end plate or lower 48, and the press-on or upper end plate 50 are connected to the cover section 28 by alignment bolts 54. Although only one of the alignment bolts 54 is illustrated in Figure 1 , it will be understood that a pair of alignment pins or pins engage the cam ring 38, the wear end plate or lower 48 and the press-on or upper end plate 50 to hold them against a movement relative to the cross section. cover 28. The cam ring 38, the rotor 40, the fins 42, the wear end plate or lower 48 and the press-on or upper end plate 50 are connected to the cover section 28 by a pair of pass-throughs. alignment tools in the same manner as disclosed in the US Patent Application co-pendingSerial No. presented by
Bruce C. Noah and entitled "Rotary Devise and Method of Assembly" (Registry No. TR (RG) -2211, Project No. 003652). Bypass Valve Assembly During the rotation of the drive shaft 44 and the rotor 40 in relation to the cam ring 38, the fins 42 cooperate with the cam ring and the end plates 48 and 50 to form the working chambers of variable volume. The fluid is pumped from the variable volume working chambers to a discharge chamber 58 disposed between the pressurized end plate or upper 50 and the main section 26 of the housing 24. The discharge chamber 58 is connected with a connection outlet 62 (Figure 4) through the outlet passages 64 and a bypass valve assembly 66. The relatively high pressure fluid is conducted away from the outlet connection 62 and the pump 20 through a conduit download 72 (Figure 2). The diverter valve assembly 66 (FIG. 5) is generally disposed in a cylindrical deflection valve chamber 76. The diverter valve assembly 66 includes a diverter valve member 80, which is axially movable in the bladder chamber. deflection valve 66. A pressure relief valve 82 is mounted on the diverter valve member 80. A stationary port plug 84 is provided in the main section 26 of the adjacent housing at the far right (as noted in Figure 5) of the diverter valve member 80. The fluid discharged from the work unit 22 (Figure 1) is led through a cylindrical hole 86 (Figure 5) into the plug of the orifice 84 towards the discharge conduit. (Figure 2) which is connected with an internally threaded connector 88. A radially extended passage 92 (Figure 5) in the plug of the orifice 84 directs the fluid under pressure from the orifice 86 towards the passage 94 formed in the main section of the housing 24. The passage 94 connects in a fluid communication with a pressure chamber 96 at the left end (as seen in Figure 5) of the diverting member member 80. The pressurized fluid in the pressure chamber 96 and a spiral spring 98 pushes the diverter valve member 80 towards the initial position shown in Figure 5. When the pressurized fluid in the exit passage 64 exceeds the combined influence of the fluid under pressure in chamber 96 and spiral spring 98, the member of v l. Deflection cell 80 moves to the left (as seen in Figure 5) to connect exit passage 64 - with a bypass passage 102. Fluid from bypass passage 102 is led to an inlet passage. 104 (Figure 9). So this fluid is used at a relatively high pressure by deviating from the outlet 64 to the diverting leg 102 to pressurize the inlet or feed fluid. Main Housing Section The main section 26 (Figure 6) of housing 24 is a one piece metallic casting. The main section 26 has a generally cylindrical wall 106 (Figures 6 and 10), which form a chamber of the cylindrical work unit 108 for the work unit 22 (Figure 1) A plurality of holes for the retainer pins 112 (Figure 1) 6) are formed in the main section 26. The holes for retainer bolts 112 in the main section 26 are axially aligned with the tapered holes in the cover section 28 (Figure 3). the retainer bolts 32 extend through the holes 112 in a threaded coupling with the holes in the cover section 28. According to one of the features of the present invention, the main section 26 of the housing 24 is constructed in such a manner Such a way as to allow a supply conduit or fluid inlet 116 (Figure 2) f to be connected to the main section 26 at a selected location of three different locations. So that the fluid supply fluid 116 can be connected to the right side of the main section 26, in the manner indicated in the solid lines in Figure 2. However, if desired, the main section 26 can be manufactured in such a way as to allow the fluid supply conduit 116 to be connected to the left side of the section main, in the manner indicated in the dotted lines of Figure 2. Alternatively, the main section 26 can be manufactured, so as to allow the fluid supply conduit 116 to be connected to a central portion of the main section, in the schematically indicated on the dotted lines in Figure 2. The main section 26 of the housing 24 has a vertical pipe section 120, which projects up and to the sides (Figures 6 and 7) from the wall 106. The section vertical tube 120 includes three vertical tubes which are a right vertical tube 122, a left vertical tube 124 and a central tube 126. Each of the tubes 122, 124, and 126 has the potential fabric To be connected with the fluid supply conduit 116. During the construction of the pump 20, one of the three tubes 122, 124 and 126 is selected for connection to the fluid supply conduit 116 (Figure 2) . The selected tube 122, 124 and 126 is then perforated and tapered to form an inlet connector for use in the connection of the fluid supply conduit 116 with the main section 26 of the pump 20. In the pump embodiment illustrated in the Figures 1-11, the right tube 122 is perforated and tapered to form an input connector 130 (Figure 8) for connection to the fluid supply conduit 116 (Figure 2). The left tube 124 (Figure 8) is intact to the left as in its molten part condition. Similarly, in its original or casting condition, the central tube 126 (Fig. 1) has a cylindrical recess 138, which extends in the tube section 120. The right and left tubes 122 and 124 have coincident center axes (Fig. 8) extending parallel to a central axis of the deflection valve chamber 76. The central tube 126 has a central axis extending perpendicular to the coinciding central axes of the radial and left tubes 122 and 124. The central axis of the central tube 126 moves to the left (as seen in Figure 3) of the coincident center axes of the right and left tubes 122 and 124. the ability to connect the fluid supply conduit or inlet 116 with any of one of the three tubes 122, 124 and 126 (Figure 2) allows the pump to be used in very different situations. So, it is contemplated that in certain situations, it is desirable to have the fluid supply or inlet conduit 116 conested are the right pipe 122, in the manner shown in the solid lines in Figure 2. However, in In other situations, it is contemplated that it would be desirable to have the inlet lead 116 connected to any tube in the right tube 124 or in the center 126, in the manner schematically in the dotted lines of Figure 2. Since the same section can be used. 26 of the housing 24 when the fluid supply conduit 116 is connected with any of the right, left or center pipes 122, 124 and 126, facilitating the manufacture of the pump 20. The right tube 122 (as seen in FIG. Figure 8) is connected to the main input passage 104 by a passage of the input connector 142 (Figure 8). The passage of the input connector 142 is drilled in the tube section 120 of the main section 26 of the housing 24. The passage of the input connector 142 extends from the input connector 130 to the main input passage 104. This originates that the main inlet passage 104 is connected in a fluid communisation are the diverting valve chamber 76 via the bypass passage 102 and with the input connector 130 through the passage of the input connector 142. Seal Drain A seal assembly 148 (Figures 1 and 11) is provided to block the leakage of fluid along the driving brake 44 during the operation of the pump 20. The seal assembly 148 is arranged in an annular seal chamber 150. The seal chamber 150 is located between an annular main or outer bearing assembly 152 and an annular inner bearing assembly 156. The annular seal assembly 148 engages the sub-section 28 and the flesha motor 44 to block the flow of fluid from the work unit 22 along the drive shaft 44 to the external pad assembly 152. During the operation of the pump 20, the fluid that leaks along the drive shaft 44 will accumulate in the portion of the seal chamber 150 disposed between the seal assembly 148 and the internal bearing assembly 156. According to an embodiment of the present invention, A seal drain passage system 160 is provided for dispensing the fluid from the seal chamber 150 to the inlet by the pump 20. The seal drain 160 system includes a passage 164 formed in the cover section 28 ( Figures 1 and 11). The seal drain passage system 160 also includes a passage 166 (Figures 10 and 11) formed in the main section 26 of the housing 24. The passage 166 extends from an annular multiple passage 170 (FIG. 11) hasia. the input sonestor 130 (Figure 8). During the sonusction of the pump 20, the connector 130 in the right tube 122 was selected for connection are the fluid supply probe 116 (FIG. 2). By
Thus, the recess as the casting in the right pipe 122 is drilled and tapered to form the input consti- tute 130 (Figure 8), the passage of the input connector 142 is drilled in the pipe section 120 to sound the Input connector 130 in a fluid communisation are the main input passage 104. The passage 166 (Figure 10) is drilled between the input connector 130 and the annular multiple passage 170 (Figure 11). The seal drain passage 166 in the -prinsipal 26-section is illustrated schematically in the Figure
11 that it is in the same plane as the seal drain passage 164 in the sub-session 28. However, the seal drain passage 166 in the main session 26 is now moving to the deresha (as shown in FIG. see in Figure 8) of the drain passage of the sub-session 166 (Figure 11). This is because the seal drain passage 166 (FIG. 10) extends between the inlet sonder 130 in the waste tube 122 (FIG. 8) and the passage of the annular manifold 170 (FIG. 11). The passage of the annular manifold 170 (FIG. 11) is formed between the sub-session 28 and the prismatic portion 26 of the housing 24. So that a siliceous portion 3,74 of the sub-portion 28 is received telessópisamente in a cylindrical opening in the chamber of the pump unit 108 (Figure 11) in the main section 26 of the housing 24. The passage of the annular manifold 170 is formed between the sill portion 174 of the sub-session 28 and the prismatic session 26 of the housing 24 The suitable annular seal rings 178 and 180 are provided between the cylindrical end portion 174 of the sub-section 28 and the main portion 26 of the housing 24 to block the flow fluid from the passage of the annular manifold 170. During the operation of the pump 20, the fluid leaks along the drive shaft 44 through the internal pad assembly 156 in the seal chamber 150. The seal assembly 148 further blocks the leakage of the fluid. This is prevented by driving the fluid from the seal chamber 150 through the seal drain passage 164 into the passageway of the fluid. annular manifold 170. The fluid is conducted from the annular manifold passage 170 to the seal drain passage 166 in the main section 26 of the housing 24. The seal drain passage 166 is provided in a fluid somunisation are the inlet connector 130 (Figure 10). Therefore, a fluid flow from the seal chamber 150 through the seal drain passage system 160 is formed by the inlet fluid or conveyed feed through a fluid supply or intake manifold 116. hasia the input sonestor Alternate Modalities In the embodiment of the invention illustrated in
Figures 1-11, the fluid supply conduit or inlet 116 connects to the right tube 122 (Figure 2) in the main section 26 of the housing 24. In the embodiment of the invention illustrated in Figure 12, the condusto of The fluid inlet 116 is provided with the left tube 124, in the manner indicated schematically in the dotted lines in Figure 2. Since the embodiment of the invention illustrated in Figure 12 is generally similar to the embodiment of The invention illustrated in Figures 1-11, similar numbers will be used to designate similar components, the letter the suffix letter "a" which is associated with the numbers of Figure 12 are in order to avoid confusion. In the embodiment of the invention illustrated in Fig. 12, the inlet or fluid supply conduit 116 (Fig. 2) is to be consisted of the left tube 124a (Fig. 12). Therefore, a recess 186 in the right tube 122a remains in a sound like that of the cast piece, while a recess in the left tube 124a is punctured. and tapering to form an input connector 188 having the same construction as that of the input connector 130 (Figure 8). The supply or fluid inlet conduit 116 (Figure 2) is con- tained as the inlet soneror 188 (Figure 12). An input input slot 192 is drilled in the main session 26a to connect the input sonder 188 in a fluid somunisation with the input port -main 104a. The main inlet passage 104a is also provided in a fluid somunisation are the bypass valve chamber 76a by a bypass passage 102a. A seal drain passage 194 (FIG. 12) is pierced between the inlet constler 130 and a passage of the annular multiple formed between the prismatic portion 26a of the housing 24a and a subsection session (not shown) of the housing 24a. The seal drain passage 194 extends to the passage of the manifold in the same manner in which the seal drain passage 166 extends in the passageway of the annular manifold 170 (FIG. 11). In the embodiment of the invention illustrated in Figures 1-11, the entrance sonar 116 are shown in the right tube 122 (Figure 2). In the embodiment of the invention illustrated in Figure 12, the input condusto 116 is connected to the left tube 124a. In the embodiment of the invention illustrated in Figure 13, the input condusto -116 is sonesta are sentral tube 126 in the manner illustrated in dotted lines in Figure 2. Since the embodiment of the invention illustrated in Figure 13 is generally similar to that of the embodiment of the invention illustrated in Figures 1-11, similar numbers will be used to designate similar components, the suffix letter "b" is associated with the numbers of Figure 13 to avoid confusion. In the embodiment of Invension illustrated in Figure 13, the center tube 126b is drilled and tapered to form a conestor input 200. An input passage 202 sonestor drilled to sonestar the sonestor inlet 200 in fluid somunisación with Main entry passage 104b. The diversion passage 102b conies to the deflection samara in a fluid somunisation are the prismatic entry passage 104b. A seal drain passage 204 is drilled from the inlet sonder 204 to the annular manifold passage 170b. The passage of the annular manifold 170b is the seal drain passage 204 in fluid communication with the seal drain passage 164b and the seal chamber 150b. Orientation of the Prinsipal and Cover Sessions It is stated that the pump 20 will be used in very different environments. Thus, the pump 20 can be used as a delivery potentiating fluid supply pump for a steering potency system in a vehicle. Different amounts of space are available in the engine compartment of different vehicles. In order to allow the pump 20 to be used to be different vehicles, the orientation of the main section and the deck section can be changed in a reciprocal relationship. The pump 20 can be mounted with the pipe section
120 in the main section 26 of the housing 24 extended upwards in the manner illustrated in Figures 2 and 14. However, if desired, the orientation of the main section 26 of the housing 24 can be changed by means of 90 In recession are the sub-session 28. Thus, the main session 26 of the housing can be rotated through 90 ° in a direction in the clockwise direction from the position shown in Figure 14 to the position shown in FIG. Figure 15. When the orientation of the main section 26 of the pump 20 can change in recession is the orientation of the cover section 28, the bolts 32 (Figure 3) are loosened and the sub-section 26 is rotated around the sentral axis of the drive shaft 44. The work unit 22 is fixedly secured with the cover section 28 by alignment pins 54 (Figure 1). Therefore, when the retainer bolts 32 have been removed from the cover section 28, the main section 26 of the housing 24 is rotated in relation to the work unit 22 and the sub-session 28 in a directionally sensitive direction. clockwise from the position shown in Figure 14 to the position shown in Figure 15. The retainer bolts 32 are then threaded to the -subsequent session 28. The passage of the annular seal manifold 170 (Figure 11) in the seal drain passage system 160 allows the seal drain passage 166 in the main station 26 to be connected in a fluid somunisation are the seal drain passage 164 in the deck session 28 when the The main section is in any orientation shown in Figure 14 or the orientation shown in Figure 15 in relation is the sub-session 28. The main session 26 of the housing 24 can be pivoted through 180. in recession they are the deck session from the position shown in Figure 14 towards the position shown in Figure 16. During this movement -of the main section 26 in relation to the sub-clamp section, the alignment pins 54 clamp to the unit The main section of the housing 24 is rotated in the main section 24. The main section 26 of the housing 24 can also be pivoted in a counterclockwise direction from the position shown in Figure 14 to the position shown in Figure 17. Thus, the main session 26 and the deck session 28 may have a reciprorable orientation which is the result of any orientation of any of the orientations illustrated in Figures 14, 15, 16 and 17. In each of the orientations of the sessión previous example (Figures 14, 15, 16 and 17), the passage of the annular multi-foot 170 with the seal chamber 150 and the seal drain passage 164 in the The sub-session 28 in a fluid communication is a seal drain passage in the main section 26. Although the four positions illustrated in Figures 14-17 are selected for the main session 26 of the housing 24, the orientation of the Work 28 remains constant since the alignment pins 54 hold the cam ring 38, the wear end plate or lower 48 and the press-on or upper end plate 50 against rotation relative to the cover section 28. The fluid supply conduit 116 may be connected to one of any of the tubes 122, 124 or 126 in one of the orients of the main section of Figures 14, 15, 16 and 17. Those with experience in the art will persist. the improvements, changes and modifiations of the description of the previous invention. It is intended that such improvements, changes and modifications within the skill of the teasiness be subverted by the appended claims.
