    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 pilot signal control assembly (10) controls the pilot signal of a valve (18) which is connected to regulator, typically a booster regulator (12). The valve (18) receives air from an air supply (14) and, pursuant to an error signal (E(t)), defined as the command signal (C(t)) less a modified feedback signal (F(t)), modifies its output, the pilot pressure signal. The booster regulator (12) receives the pilot pressure signal and modifies its output (P o (t)) accordingly. A feedback loop (24) transforms the output pressure (P o (t)) into a voltage signal. The voltage signal is multiplied by a proportional factor (A) based on the size of the booster regulator (12). In a signal subloop (30) of the feedback loop (24), the first derivative is taken of the voltage signal. The multiplied signal and the first derivative are added to create the feedback signal (F(t)) which is eventually subtracted from the command signal (C(t)) to create the error signal (E(t)). The first derivative portion of the feedback signal (F(t)) rapidly approaches zero as the output pressure (P o (t)) of the booster regulator (12) gradually approaches the targeted pressure.

    摘要: A control valve having a valve body (58), seat member, valve member (74), and solenoid (22) including a housing (24), bobbin (26), and coil (28). The valve member (74) has a head portion (78) disposed within the bobbin (26) and a valve portion (80) disposed within the valve body (58) that has a seat engagement member (82) operating to open and close ports (96, 98) in the valve body (58) when the valve member (74) slides between first and second positions. A permanent magnet (122), disposed within the bobbin (26), applies an attractive force (128) of variable magnitude to the valve member (74) in a direction opposing a biasing force (120) created by a biasing component (118). Pulses of electric current applied to the coil (28) change the variable magnitude. The permanent magnet (122) pulls the valve member (74) to the second position when the attractive force (128) is greater than the biasing force (120) and the valve member (74) returns to the first position when the attractive force (128) is less than the biasing force (120).

    摘要: A diaphragm valve (20) includes a solenoid body (26) having a coil and a pole piece. An armature is configured to slide in the solenoid body (26) along a longitudinal axis between energized and de-energized positions. A valve body cartridge (24) is connected to the solenoid body (26). A valve member, connected to the armature, is configured to slide within the valve body cartridge (24) when the armature moves. A biasing member acts to normally bias the armature toward the de-energized position. A diaphragm, extending inwardly from the valve body cartridge (24) towards the valve body, is received between the armature and the valve member. A diaphragm support sleeve includes a support sleeve wall defining a sleeve cavity that receives the armature and a support sleeve flange that extends inwardly from the support sleeve wall to abut and support at least part of the diaphragm.

    摘要: A normally open solenoid operated modular valve includes a solenoid body receiving a coil and pole piece. A polymeric material valve body portion is releasably connected to the solenoid body. An armature/valve member slidably disposed in both the solenoid body and the valve body portion has a male threaded end shank. A polymeric material thread-in poppet/valve member includes an internal threaded portion engaging the male threaded end shank to retain the thread-in poppet/valve member on the armature/valve member. A resilient material valve ring is retained on the thread-in poppet/valve member. A cylindrical tube portion receives an armature/valve member rod portion. A biasing member acts against the armature/valve member and thereby acts to normally bias the valve ring away from contact with a valve seat surface created in the valve body portion defining a modular valve valve normally open position.

    摘要: A pressure balanced solenoid operated valve includes a solenoid portion having a coil. A valve member portion is connected to the solenoid portion. The valve member portion has a body including: first and second valve seats; a first cavity positioned between the first valve seat and a valve outlet port. A valve member slidably disposed in the body has a resilient valve element positioned between the first and second valve seats, the resilient valve element when in direct contact with the first valve seat defining a valve closed position. A bleed port created in the body between the first valve seat and the valve outlet port and opening into the first cavity provides a flow path for a pressurized fluid present at the second valve seat in the valve closed position to continuously flow out through the valve outlet port.
