[Prior art] Directly actuating or actuating a pneumatic valve is well known to me for controlling the flow of pressurized air through it. Direct-acting valves can be used alone or in conjunction with, for example, spool valves and regulators, which then control the flow of pressurized air to and from different pneumatically actuated devices (such as a push clutch, air brake, cylinder or any other pneumatic device or Requires precise control of air operated devices). More specifically, two-way, three-way, and four-way direct-acting valve assemblies are common users in these environments. Similar valves generally include a valve body with a valve perforation formed in the valve body. A valve member is supported within the valve hole, and it directly moves from one position to another position in response to the force applied to the valve member by an actuator. Ports are used to connect the valve assembly to the system supply pressure, and the different actuation settings that the valve can control. The actuator is generally an electromagnetically actuated solenoid valve that is enabled to move the valve member to a predetermined position within the valve perforation. A return spring n is used to bias the valve member back to a known un-enabled position. This type of valve is used in a variety of manufacturing environments where high flow rates and very fast response times are desired. As the technology of these valves has improved, there is also a need to increase the design of smaller valves in an operating environment that continues to reduce hardware size. In addition, technological advances have made the main outlet valve

In fact, the need for faster speeds and shorter reaction times is a continuing need for this type of valve. Whatever the design obstacles such as σ in the past have been limited can reduce the size of the 阙 assembly: 'while at the same time increasing the speed range. When the valve member and the valve perforation are smaller than a predetermined size, the return spring may not be able to provide sufficient physical size and mechanical strength to overcome the inertia of the valve member. In addition, after the Tian valve member is actuated n to M directions, friction and surface adhesion can be established at the valve member dense 1-the father boundary of the valve hole. These motors are attached to the relevant surface and act to prevent the valve member from moving in the opposite direction and reduce the valve speed and therefore increase the valve response time. In this month, the 'recovery yellow' may not provide sufficient biasing force to quickly or effectively move the valve member from its enabled position, and return to its inactive state when the actuator = force is removed Can position. When this happens ^ 'The actuator device loses accurate control. To overcome this shortcoming, different design countermeasures have been proposed. In any case, among the countermeasures proposed by related technologies, they still suffer from the disadvantages of requiring additional mechanisms, hardware, or the need to install valves remotely. For example, in a design countermeasure proposed by a related art, it includes the use of a dual set of electromagnetic actuators to move the valve member in the opposite direction. Therefore, the return spring is replaced with an electromagnetic actuator such as a solenoid valve. Unfortunately, this approach adds complexity to one solenoid valve and its associated parts, and at the same time creates another size limit. On the other hand, it has been proposed in related technology to enable a single electromagnetic actuator in two directions. Regardless, these single electromagnetic actuators require huge double-wound actuators to

Therefore, the direct actuating chambers using huge single-electromagnetic actuators are generally installed at a remote position relative to the pneumatic actuating device they control. Unfortunately, the remote configuration of the valve: the design of the smaller, lighter, and more accurate valve that can be brokenly installed near the actuating device is ineffective. At the same time, they must be interconnected via a conduit or its jaw moving path. This requires additional hardware and fittings, which reduces the aerodynamic efficiency and leads to pipeline losses in the system. '' Although the larger traditional valves used by Caimu (whether it requires remote configuration or additional other components) have been roughly effective for the purpose they are intended to use, however, ten, only this technology * still has a hold ~ Simplified pneumatic The requirements of the system, and hence the cost of clothes & and / or assembly, are always smaller but still more accurate: fast acting direct acting pneumatic valves. Smaller direct actuation chambers can be positioned very close to the actuation system components, thus shortening the flow path, reducing or omitting additional tubing and hardware, and increasing the efficiency of pneumatic flow. Unfortunately, design countermeasures have been proposed in related technologies. However, when the size of the valve member and the perforation cannot be reduced, the return spring can quickly and effectively return the valve member of the fast-acting valve to a non-β position. Problems with limit points. [Summary of the Invention] The valve body that should be inserted into the valve, and at least the single-round branch-shaped mouth, Libentuming overcomes the design obstacles and other shortcomings of related technologies that directly actuate the valve assembly. More specifically, the present invention is a directional-direct-acting valve assembly including a pressurized air supply inlet communicating with a pressurized air source.

At the same time, an air-assisted passage containing a pneumatic pressure source is included, which is combined with the biasing member to actuate to move the valve member in a direction opposite to the movement caused by the actuator. The direct-acting valve of the present invention has a unique advantage over the known ones of the related art. The air assist passage provides a pneumatic pressure source from the pressurized cylindrical port, which is combined with the biasing member and is actuated to move the valve member in a direction opposite to the movement caused by the actuator. Important air-assisted air assist helps to move faster. The air-assisted air cell assembly using the present invention may include relatively sloppy components that require less force than those without line assist. Because the biasing member generates less force, the actuator has less force to overcome: therefore moving the valve member to its first position more quickly. In addition, the bias ^. Hole thinning together with the-when, when the solenoid valve assembly is disabled, can quickly and effectively move the valve member away from its second or enabled position. The wire assist path provides the necessary mechanical thrust to assist in moving the valve member to the disabled position. Therefore, the direct-acting valve assembly of the present invention overcomes the shortcomings and disadvantages of the traditional wide assembly. When the conventional valve assembly is downsized, the separate biasing member is insufficient to provide the size and mechanical strength of the entity, and can be repeated.

A valve member (shown generally as 46) moves between predetermined positions in the valve perforation 36 to selectively guide the pressurized air from the inlet port 3G through the cylindrical port 32 and the outlet port center, which will be described in detail below. The pair of tail end bundles 48, 50 are respectively received in one of the pair of open ends 42, 44 of the valve body 12, and act to retain the valve member 46 within the valve perforation 36 ', which will be described in detail later. The valve member 46 further includes a pair of opposing valve heads 6G, 62 provided at either end of the valve member flutter, and at least −valve members 54 and 56 are formed in the valve member 46 at the opposing valve heads 60, 62. between. The valve element "is operable to selectively direct the flow of air from the port 3 () through the valve perforation% to either the cylindrical port 32 or the outflow port 38. Each tail end piece 48, 50 have a central perforation 74, 76, which respectively accept the opposing heads 60, 62 of the valve member μ, and can cause the valve member to slide within the valve body 12. The valve member 46 shown best in FIG. 3 includes The annular groove 70, which receives the O-ring seal 72, can slidably fit the central perforated openings 74 and 76 defined in the tail bundles 48 and 50, respectively, to prevent the inside of the valve perforation 36. Pressurized air leaks. In a specific example, the valve member 46 may be a poppet valve that is supported within the valve perforation 36 to reciprocate there to control fluid flow through the valve body 12. In this case The poppet valve member 乜 is a better O: \ 88 \ 8880l.DOC -11-1240050 plastic insert, which is tied to a specific area of the valve member 46 with rubber, and ground to a specific size to form, for example, Puppet element 54, 56. In any case, the skilled person hereby states that it should be understood that the present invention is not limited to How to use it. On the contrary, the present invention can be used with any other related direct actuated valves, including but not limited to, for example, short tube valves' flat rubber valve, tongue valve, pilot valve, or adjacent to or away from the pneumatic actuating device The valve assembly used. The end beam member 50 is cup-shaped and includes a plurality of cylindrical passages 64 defined in the end beam member 50 and spaced radially from each other. The cylinder passage 64 is provided at The valve perforation 36 is in fluid communication with the corresponding abutting port. The biasing member 66 is placed between the tail beam member 50 and a groove 68 formed in the opposing valve head 62 of the valve member 牝. In a preferred embodiment, the biasing member is a coil spring 66. In general, the skilled person will understand that any generally known biasing member that can provide sufficient force in one direction may be suitable for this application In addition, the average skilled person should understand that because a large number of biasing members are applicable in this environment, it is not suitable to attempt to classify them all here. On the contrary, this should be sufficient for the purpose of narrative and example to state Reply The spring 66 can apply a fixed biasing force to bear against the valve member 46 and to the left as shown in Figs. 2 and 3. In addition, the same is true for the other details described in Figs. 4-6 of the present invention. A plurality of valve seats 84, 86 are presented. The valve seats 84, 86 are combined with the valve elements 54, 56 to seal different passageways living in the valve body 12, which will be described in detail later.

Other valve seats may be defined near the end 56 of the tail bundle 50. In the specific example shown in heads 2 and 3, the valve seat% is arranged at the end 51 of the bundle member 5G. The tail end bundle member 50 can be adjusted by screwing within the: hole 36 of the valve body 12, and can therefore be adjusted and placed within the tail: 44 of the valve hole 36. Therefore, it is possible to control the sealing of the seats 84 and 86 by applying a force to the valve member 在 at the position of the tired teeth on the tail bundle in the valve body η. The end of the tail end member 50 is placed on the valve, and the position within the tooth 6 is to define a predetermined "open" and closed position 10 of the reading assembly 10, and thus the stroke length of the valve member 46 is set. In order to prevent pressurized gas from leaking in the valve perforation 36, the tail bundle member further includes the annular grooves 91 and 93 for receiving the Q-shaped ring seal 92, and the valve at the tail bundle member 48 50. The body 12 further includes an annular groove 80 for receiving an O-ring seal 82. As shown in FIG. 4 and illustrated in FIG. 10, the electromagnetic actuator 14 is a solenoid valve assembly mounted on the 鳊 σ 卩 face 24 of the main body. The poppet valve member 46 is actuated in one direction or to the right as shown in FIG. 2 under the sound of the electric door and the shirt. To this end, the solenoid valve assembly 14 includes a housing, which is generally designated ⑽. The housing ⑽ includes an end plate 104 adjacent to the pole plate piece 102 adjacent to the valve body 12 and disposed at the opposite pole plate piece 102, and a solenoid valve can or frame 106 extending therebetween.

The conductive harness 11 is connected to a current source via lead lead (generally designated 114). Lead lead 114 is supported on end cap 104 and includes lead insert 116, electrical contact 118, and lead 120. The lead 120 is operatively connected to a current source. The current flows through the coil 108 in one direction, and the electromagnetic force generated by it is controlled by the control current (not shown in the figure).

Another solenoid valve 'with a floating armature is provided with an invalid movement such as described in the prior art Wu Guo Patent No. 4,438,418 or 3,538,954. Each of these patents is assigned to the designated assignee of the present invention, and the disclosures of these patents are incorporated herein by reference. Therefore, a general skilled person should understand from the narrative that the exact style (whether electromagnetic or otherwise) of the actuator of the narrative, which * constitutes the scope item of the present invention. It should be further understood from the description of the present invention that although the specific example of the valve assembly 10 of the present invention is depicted in this description as the three-way valve shown in Figure γ · 3, the present invention can also be replaced by two Path valve style (not shown in the figure), four-way valve style (as shown in Figure 4_5), or similar specific objects. The spare valve member 46 has been moved to the right by the solenoid valve assembly 14 as shown in FIG. 3, and the valve element 56 has been moved into a valve seat 86 sealedly fitted to the end 51 of the tail end member 50. In this operating configuration, fluid flows between the inlet port 30 and the cylindrical port 32, and can deliver pneumatic pressure to any downstream device. In any case, when the valve member 46 is in this operating configuration, friction and adhesion can be generated between the valve member 46 and the central perforated openings 74, 76 of the tail beam members 48, 50. These forces act to resist production in the opposite direction via the biasing member 66 once the solenoid valve assembly 14 has been disabled.

Therefore, these forces act to reduce the speed and efficiency with which the valve member 46 is returned to its first position. In addition, reducing the size of the biasing member 66 may cause a reduction in the generated force, thereby causing a slower valve response time. To overcome this problem, the valve assembly 10 of the present invention includes an air-assisted passage, which is generally not designated as 94. In the specific example shown in FIGS. 1-3, an air assist passage 94 is formed in the valve member 46 and provides fluid between at least one cylindrical port 32 and a groove “located in the valve head 62 of the valve member 46. Therefore, the air-assisted passage 94 provides selective fluid communication between the source of pressurized air and the recess 68. More specifically, and as shown in the figure: and], the air-assisted passage 94 includes an inlet 96 and A main passage 98. The inlet 96 extends radially with respect to the centerline " A " of the valve member. In this representative specific example, the inlet portion 96 is formed between the valve elements 54, 56 defined in the valve hole 36, and between the valve seats 84, 86. The main passage 98 provides fluid communication between the inlet site% and the groove 68. In this representative specific example, the main passage 98 is coaxial with respect to the longitudinal axis of the valve member. The air assist passage 94 provides a pneumatic pressure source from the pressurized cylindrical port 32, which cooperates with the biasing member 66 to operatively move the valve member 46 to move in a direction opposite to the movement induced by the actuator 14. Importantly, air assist helps to actuate the valve faster. More particularly, the air-assisted valve assembly 10 using the present invention may include a smaller biasing member 66 that generates less force than is needed without the need for air assistance. Because the biasing member 66 generates less force, the actuator 14 requires

In addition, once the solenoid valve assembly 14 is disabled, the biasing member 66, in conjunction with the air assist provided by the through-path 94, will be able to quickly and effectively move the valve member 46 away from its second or enabled position. The air assist passage 94 provides the necessary mechanical power to assist in moving the valve member to the disabled position. Therefore, the direct actuated valve assembly of the present invention overcomes the traditional valve after reducing the size, so that the single biasing member 66 is not sufficient to repeatedly, quickly, and effectively overcome the inertia of the valve member 46 in terms of physical size and mechanical strength. Inadequate and disadvantageous frictional adhesive forces acting on the contact surfaces between the valve member 46 and the central perforated openings 74, 76 of the tail bundles 48, 50. This allows very fast-acting valve assemblies to be constructed under traditional standards. Then an alternative, non-limiting specific example of the direct-acting valve assembly shown in Figure 4-5 of McCaw, which has the air assisted return stroke of the present invention (approximately labeled 210); the figure of the specific example is shown relative to Figure u Similar numbers increased by 200 are used to indicate the same structure.

複數個閥承座282、284、286及288呈現在閥穿孔236。 閥承座282、284、286及288分別協同閥元件252、254、 256與258以密封在閥本體212之不同的通路，此將詳述於 後。當閥構件246位於相對於特定出口埠之閉合位置時， 閥承座282、284、286及288提供密封接觸於閥元件252、 2 5 4、2 5 6與2 5 8的閥密封表面，因此中斷加壓空氣流動至 該埠口。A plurality of valve seats 282, 284, 286, and 288 are present in the valve perforations 236. The valve seats 282, 284, 286, and 288 cooperate with the valve elements 252, 254, 256, and 258 to seal different passages in the valve body 212, which will be described in detail later. When the valve member 246 is in a closed position relative to a specific outlet port, the valve seats 282, 284, 286, and 288 provide sealing contact with the valve sealing surfaces of the valve elements 252, 2 5 4, 2 5 6 and 2 5 8 and therefore Interrupt the flow of pressurized air to the port.

The bundle inserts 248, 250, and 251 are adjustably disposed within the valve perforations 236 of the valve body 212 and have upper threads to interact with the tail ends 242, 244, or any other suitable portion of the valve perforations 236. As previously mentioned, each of the bundle inserts 248, 250 has central perforations 274, 276 which receive the opposing heads 260, 262 of the valve member 246 and can be slidably moved within the valve body 212. Therefore, the positions of the tail bundle inserts 248, 250 can be set above and beyond the valve body 212, and the sealing of the valve seat can be controlled by the force applied to the valve member 246. The tail bundle inserts 248, 250 further include annular grooves 291 and 293 which receive O-ring seals 295 to prevent the leakage of pressurized air within the valve perforations 236. On the other hand, the inner bundle member insert 25 1 can be screwed on to set the position, which defines the predetermined "open" of the valve assembly 210 and O: \ 88 \ 8S801.DOC -20-1240050 2 position, and thus Set the stroke length of the valve member ice. Similar to the bundle member insert, the inner bundle member 251 may also include an annular groove 297, which is adapted to receive the O-ring seal 299, so as to prevent the leakage of the plus air in the intermediate perforation 236.

Component 246. The drawing is for example purposes only. This may be accomplished using an actuator pin lock 332 having an enlarged head 342 that extends into the beam insert 248 to close and actuate the valve member 246. As mentioned indirectly above, one of ordinary skill should understand that the particular actuating device used to provide the moving force to the valve member 246 is beyond the scope of the present invention. As mentioned earlier, it should further understand that any number of different types of actuation elements (instead of a push pin) can be used depending on the actuation I used. The actuator assembly 214, as previously stated, is used to selectively actuate the valve member 246 in a direction opposite to the biasing force of the biasing member 266 within the valve aperture 236. In this manner, the actuator assembly 214 drives the valve member to the right as shown in FIG. 4. When the actuator assembly 214 is released, the biasing member 266 returns the valve member 246 to its original position (FIG. 5 shows to (Left) 0 When the valve member 246 has been moved to the right by the solenoid valve assembly 214 as shown in FIG. 4, the valve element 256 is moved into the valve seat 286 which is hermetically sealed to the inner bundle member 25 1. In this operational configuration, fluid communicates between inlet port 230 and cylindrical port 232, and delivers pneumatic pressure to any downstream device. In any case, when the valve member 246 is in this operating configuration, friction and adhesion may occur at the interface between the valve element 256 and the valve seat 286 at O: \ 88 \ 88801.DOC -21-1240050. Once the solenoid valve assembly 214 has been disabled, these forces are applied to resist the biasing force generated by the biasing member 266 in the opposite direction. Therefore, these forces act to slow down the speed and efficiency with which the valve member 246 is returned to its first position. To overcome this problem, an air-assisted passage (shown generally as 294) is formed within the valve member 246 and extends between at least one cylindrical port 232 and a groove 268 in the valve head 262 of the valve member 246 To provide selective fluid communication between the pneumatic pressure source and the groove 294. More specifically and as exemplarily illustrated in Figs. 4 and 5, the air assist passage 294 includes an inlet portion 296 and a main passage 298. The inlet portion 296 extends radially with respect to the centerline A of the valve member. In this representative specific example, the inlet portion 296 is formed between a pair of valve elements 252, 254. The main passage 298 provides fluid communication between the inlet portion 296 and a groove 268 formed in the head portion 262 of the valve member 246. In this representative specific example, the main passage 298 is coaxial with respect to the longitudinal axis A of the valve member 246. The air assist passage 294 provides a pneumatic pressure source from the pressurized cylindrical port 232, which cooperates with the biasing member 266 to operatively move the valve member 246 in a direction opposite to the movement induced by the actuator 214. What's important is that 'Air Assist helps to actuate the valve faster. More particularly, the air-assisted valve assembly 210 using the present invention may include a smaller biasing member 266 'which produces less force than is needed without the need for air assistance. Because the biasing member 2 6 6 generates less force, the actuator 214 requires less force to overcome and therefore move the valve member 246 more quickly to its first O: \ 88 \ 88801.DOC -22-1240050 position. In addition, once the solenoid valve assembly 214 is disabled, the biasing member 266 together with the air assistance provided by the through passage 294 will be able to quickly and efficiently move the valve member 246 away from its second or enabled position. The air assist passage 294 provides the necessary mechanical power to assist in moving the valve member 246 to the disabled position. Therefore, the direct-acting valve assembly of the present invention overcomes the reduction in size of the conventional valve, so that the single biasing member 266 is not sufficient to repeatedly, quickly, and effectively overcome the inertia of the valve member 246 in terms of physical size and mechanical strength. Inadequate and disadvantageous frictional adhesive forces acting on the contact surface between the valve member 246 and the central perforated openings 2 7 4, 2 7 6 of the tail bundle 248 '250. This allows the very fast-acting valve assembly 21 to be constructed under traditional standards. Referring to FIG. 6, another alternative non-limiting specific example of the direct-acting valve assembly is shown, which has the air assisted return stroke of the present invention (approximately labeled as 3 1 0); a specific example is shown relative to FIG. 1-3 Similar numbers increased by 3 00 are used to indicate the same structure. More specifically, the valve assembly 3 10 exemplified here is also a three-way valve, and includes a plurality of components that are the same or similar to the three- and four-way valve types related to the illustrations in FIGS. 1-5. After understanding this, the valve body 3 12 of the valve assembly 3 10 has a pressurized fluid (such as air) inlet port 330 communicating with a pressurized fluid source. The valve perforation 336 extends axially within the valve body 312. The valve body 312 also includes a cylindrical port 332 and an outflow port 338, which are in fluid communication with the valve hole 336. A valve member 346 is movably supported within the valve perforation 336 and has a pair of opposed heads 360, 362. In addition, the valve member 346 includes at least one valve O: \ 88 \ S8801.DOC -23-1240050 element 354 356 known as to selectively direct the flow of pressurized air from the inlet port 330 through the valve aperture 336 to the cylindrical port 332 or outflow port 338. A plurality of valve seats 384 and 386 are present in the valve perforation 336. The valve seats 384 and 386 combine the valve elements 354, 356 to seal different passages of the valve body 312, which will be described later. When the valve member 346 is in a sealed position with respect to a specific cockroach, the valve seats 384, 386 provide a sealing contact with the beginning and sealing surfaces of the valve elements 3, 54 and 356, thereby interrupting the flow of pressurized air at the port. Unlike the open-end valve perforations shown in Figures 1-5, the valve perforations 336 are blind perforations having an open end 342 and a closed end 344. An electromagnetic actuator (such as a solenoid valve assembly), generally designated 314, is mounted on the valve body 312 at the open end 342 of the valve hole 336. The solenoid valve assembly 14 is actuated to bias the valve member 346 in the same manner as the specific example illustrated in FIG. 1β5. On the other hand, a biasing member 366 such as a coil spring is placed between the blind end 344 of the valve perforation 336 and formed between the groove 368 of one of the opposing valve head portions 362 of the valve member 346. The return spring 366 applies a constant biasing force against the valve member 346 in a direction 'that applies a force to the solenoid valve assembly 314. When the valve member 346 has been moved toward the solenoid valve assembly 3 14 as shown in Fig. 6, the valve element 356 is moved into the coupling seal at the valve seat 3 8 6 defined in the valve through hole 3 3 6. In this operational configuration, fluid is in communication between inlet 珲 330 and cylindrical port 332, and delivers pneumatic pressure to any downstream device. In any event, when the valve member 346 is in this operating configuration, friction and adhesion may occur at the interface between the seal 372 of the valve member 246 and the trailing ends 342, 344 of the central perforation 336.

As mentioned previously, these forces act to slow the speed and efficiency with which the valve member 346 is returned to its first position. To overcome this problem, an air assist passage (generally designated 394) is formed within the valve body 312, and fluid communication is formed between the cylindrical port 332 and the groove 368 in the valve head 362 of the valve member 346. The air assist passage 394 thus provides selective fluid communication between the source of pressurized air and the recess 368. In any case, the ordinary skilled person should note that the air assist passage 394 is defined within the valve body 312, and is different from the air assist passages 94 and 294 in the valve members 46, 246. More specifically, and as shown in Fig. 6, the air assist passage 394 includes an entrance portion 396 and a main passage 398. The inlet portion 396 extends axially 'within the valve body 312 relative to the movement of the valve member 346 and provides fluid communication between the cylindrical port 332 and the main passage 398. On the other hand, and in this representative specific example, the main passage 398 extends transversely to the longitudinal axis A of the valve member 346, and is in fluid communication between the inlet portion 396 and the groove 368 formed in the head portion 362 of the valve member 346 . The air assist passage 394 provides a pneumatic pressure source from the pressurized cylindrical port 332, which cooperates with the biasing member 3 6 6 to operatively move the valve member 346 to move in a direction opposite to the movement caused by the actuator 314 . Importantly, air assist helps to actuate the valve faster. More specifically, the air-assisted valve assembly 31 using the present invention may include a smaller biasing member 366 'which produces a smaller force than required without the need for air assistance. Because the biasing member 366 generates less force, the actuator 314 needs less force to overcome and therefore move the valve member 346 to its first O: \ 88 \ 88801.DOC -25-1240050 position more quickly. In addition, once the solenoid valve assembly 3 14 is disabled, the biasing member 3 $ 6 together with the air assist provided by the through passage 394 will be able to quickly and efficiently move the valve member 346 from its second or enabled position keep away. The air assist passage 394 provides the necessary mechanical power to assist in moving the valve member 346 to the disabled position. Therefore, the direct-acting valve assembly of the present invention can overcome the shortcomings and defects of the conventional valve assembly, especially when its size is reduced so that the physical size and mechanical length of a single biasing member 366 are insufficient to repeatedly, quickly and effectively. Efficiently overcome the moment of inertia of the valve member 346 and / or the frictional adhesion acting between the valve member 346 and the valve hole 336. This makes it possible to construct an extremely fast-acting valve assembly 3 1 0 which is smaller in size than the conventional standard. Operation The operation of a direct-acting pneumatic valve having an air assisted return stroke of the present invention will be described with reference to the three-way valve assembly 10 shown in Figs. 1-3. In any case, the ordinary skilled person should understand that the valve operating instructions exemplified in Figs. 1-3 can also be applied to the four-way valve shown in Figs. 4 and 5, the three-way valve shown in Fig. 6, and any other air-assisted return stroke using the present invention. Actuate the pneumatic valve directly. In operation, pressurized air is supplied to the inlet port 30. The pressurized air flows through the filter 3 i disposed at the port and enters the valve perforation 36. When the solenoid valve assembly 14 is disabled, the biasing member 66 biases the valve member 46 to the left side shown in Fig. 2 so that the auxiliary valve element 54 is hermetically fitted to the valve seat §4. In this configuration, the valve element 56 is disposed at a distance from the valve element 86, and provides a flow path between the cylindrical port 32 and the valve perforation 36. In this manner, the cylindrical port 32 exits through the valve perforation 36 and the cylindrical passage 64 and enters the outflow port 38.

Partial pressure. In this operating configuration, the valve element 54 leaves the valve seat 84 and the valve element 56 is quickly moved into the seal and engages the valve seat 86. The pressurized air is then allowed to flow through the inlet port 30, through the filter 3, into the valve through-hole 36, through the open valve element 54 and the valve seat 84, and into the cylindrical port 32. On the other hand, the interaction of the valve element 56 and the valve element 86 seals the cylindrical port 32 related to the outflow port 38. In addition, an air assist passage 94 is opened to provide pressurized air flow through the valve aperture 36 and the cylindrical port 32. Therefore, the groove 68 formed in the valve head portion 62 is similarly pressed. In any case, the force generated by the solenoid valve assembly 14 is sufficient to overcome the reverse guiding force generated by this pressure. Once the solenoid valve assembly 14 is disabled and the actuation force of the valve head 60 of the valve member 46 is removed, the biasing member 66 starts moving the valve member 46 back to its first position in cooperation with the air pressure acting on the valve head 62. position. When this happens, the valve element that forms a seal with the valve seat 86 in the enabled position will quickly leave the wide seat 86, so that the pressurized cylindrical port M (and providing air assisted pressure) flows out Exit from port 38. The valve member is tilted and moved to the left until the valve element 54 is sealed by the valve seat seat and fluid flow is completed between the cylindrical port π 32 and the outflow port port 38 through the reading member 56 ′ and the valve seat 86 passes through Valve perforation%. It should be noted that, once the valve member 46 is moving and any friction or μ force acting on the wide element% is overcome, the biasing member 66 has mechanical strength to continuously move the valve member 46 to its first-disabled position and No need for air assistance.

Importantly, air assist helps actuate the valve more quickly. More specifically, the air-assisted valve assembly using the present invention may include a smaller stabilizing member that generates less force required by the driver without the need for air assistance. Because the biasing member produces less :: 'dynamics, less force is needed to overcome and therefore move the valve member to its younger position. Xiao Chuantong ’s # Air-assisted on-off biasing component will quickly and effectively move the solenoid valve assembly from its first (or enable) position when the solenoid valve assembly is disabled. The air assist path provides the necessary mechanical thrust to assist in moving the valve member to the disabled position. Therefore, the direct-acting valve assembly of the present invention overcomes the shortcomings of the traditional valve assembly. "When the conventional valve assembly of the stomach is reduced in size, the separate biasing member is not enough to improve the size and mechanical strength of t, shells, and iteratively. It also quickly and effectively overcomes the inertia of the valve member and / or exceeds the friction and adhesive force acting between the valve body and the central perforation. This volume describes the structure of the direct-acting valve assembly 10, 210, and 3 10 as described above. Unique advantages over related valves as known. Valve assemblies ⑺, 210 and 310 can be operated very quickly. In addition, the size limitations of conventional valve assemblies are overcome 'and valves with smaller size ranges become feasible. More In particular, the size of the air-assisted passage for a very fast-acting valve assembly is extremely important in terms of size. Therefore, it is easy to be applied in an environment where air-conditioning is the first consideration.
