摘要： A valve assembly includes a valve body having a valve bore (32). A valve member (36) is slidably disposed within the valve bore between first and second stop positions. First and second valve elements (76,78) of the valve member have first and second sealing surfaces (80,82) equally angled with respect to a valve member longitudinal axis. Each of the first and second sealing surfaces (80,82) is oriented parallel with conical shaped first and second seat surfaces. Both first and second seat surfaces are equally angled with respect to the longitudinal axis and have an adjustable spacing such that the first sealing surface contacts the first seat surface and the second sealing surface contacts the second seat surface simultaneously in the first stop position.

摘要： A solenoid operated modular valve includes a solenoid body having a coil and a pole piece positioned in the solenoid body. A valve body cartridge is connected to the solenoid body. A polymeric snap-in seat assembly includes first and second deflectable claw arms each having a barb engaging the valve body cartridge retaining the snap-in seat assembly in direct contact with the valve body cartridge. A seat engagement face when contacted by a valve seal member defines a valve closed position, and is displaced away from the seat engagement face in a valve open position when the coil is energized. A valve body cartridge body end portion includes a barb engagement face having pitched contact edges each having a continuous pitch directly contacted by the barb of the first and second deflectable claw arms to rotatably and frictionally lock the snap-in seat assembly to the valve body cartridge.

摘要： A pilot operated valve assembly (10) including a valve body (12) having a pressurized air supply inlet port (28) in communication with a source of pressurized air and at least one cylinder passage (30, 32). A main valve bore (34) extends axially within the valve body (12) and a main valve member (44) is movable between predetermined positions within the main valve bore (34) to selectively direct pressurized air from the inlet port (28) through at least one cylinder passage (30, 32). A pilot valve bore (122) is formed within the main valve member (44) and extends coaxially relative to the main valve bore (34). A pair of short pilot cylinder ports (136, 138) spaced apart from one another extend between the main valve bore (34) and the pilot valve bore (122). A pilot valve member (140) is movable between predetermined positions within the pilot valve bore (122) to selectively direct air from the pilot valve bore (122) through alternating ones of the pilot cylinder ports (136, 138) to act upon the main valve member (44) thereby moving the main valve member (44) between predetermined positions.

摘要： A pneumatic pressure regulator assembly (10) including a regulator housing (12) having an inlet (50) adapted for fluid communication with a supply of pneumatic pressure, an outlet (52) adapted to provide pneumatic pressure to a downstream pneumatically actuated device at a regulated pressure, and a regulator valve assembly (46). The regulator valve assembly (46) has a valve member (58) movably supported within the regulator housing (12) between an open and a closed position. A piston assembly (48) acts to bias the valve member (58) to its open position when the outlet pressure is below a predetermined value. The piston assembly (48) includes a pressure responsive surface (106) defining a geometric shape with a major and a minor axis wherein the major axis A is greater than the minor axis B. The piston assembly (48) is responsive to pneumatic pressure flowing between the inlet (50) and the outlet (52) to reduce the biasing force acting on the valve member (58) such that the valve member (58) moves to its closed position when the outlet pressure exceeds a predetermined value.

摘要： A self-latching solenoid valve assembly including a valve body having a pressurized air supply inlet port for communicating with a source of pressurized air and at least one cylinder port. A valve member is supported in the valve body so as to be movable between predetermined positions to selectively direct pressurized air from the inlet port to at least one cylinder port. A biasing member is employed to move the valve member in one direction and a solenoid assembly (14) is used to move the valve member in an opposite direction. The solenoid assembly (14) includes a housing with a solenoid coil (56) supported therein and a fixed ferromagnetic pole piece having a passage extending therethrough with a pushpin (84) movably supported in the passage. A ferromagnetic latch is also supported by the housing and spaced from the pole piece. A permanent magnet is disposed between the latch and the pole piece. The magnet is movable toward the pole piece under the influence of an electromagnetic flux generated by a pulse of current generated through the coil (56) in one direction thereby driving the permanent magnet against the pushpin (84) to move the valve member to one predetermined position. In addition, the permanent magnet is also movable away from the pole piece and toward the latch under the influence of an electromagnetic flux generated by a pulse of current flowing through the coil (56) in an opposite direction. When this occurs, the biasing member moves the valve member to another predetermined position. A control circuit (70) for changing the direction of the current through the coil (56) is also disclosed.

摘要： A valve assembly controls a pressure sent from a valve to create a pilot signal used to control a mechanical booster regulator. An independent feedback line extends from both the output of the valve and the output of the mechanical booster regulator wherein the outputs are scaled after a transducer in each feedback line converts the information received from the pressures into voltages. The difference in the voltage is integrated and added to the input command signal which dictates the parameters of the mechanical booster regulator operation. The voltage feedback from the pilot pressure is then subtracted from the modified command signal. The feedback signals approach a negligible correction as the mechanical booster regulator approaches the designed output pressure because the integration is eliminated and the pressures cancel each other as the system approaches a static condition.
