摘要:
A system and method for operating a solenoid valve is disclosed. The solenoid valve is operated by moving a first valve element (4) with respect to a second valve element (6, 7) a first distance. And then pulling the second valve element (6, 7) with the first valve element (4) a second distance where the second valve element (6, 7) moves against resistance from a seal (8) and where the movement of the second valve element (6, 7) opens a gap with respect to an orifice (10). The second element (6, 7) then moves a third distance under spring load to open an increased gap with respect to the orifice (10).

A booster actuator (10) may be positioned between the solenoid (12) and a valve (14), and increases the energy output from the solenoid to activate the valve. The booster actuator (10) may include a force input member (28) and a force output member (30) each linearly movable with respect to a body (20) from an initial position to an activated position. A coil spring (46) biases the input member to the initial input position, while a plurality of disk springs (48) bias the output member (30) to the activated output position. A plurality of linking members (32) each pivotable with respect to the body normally retain the force output member in the initial position, but upon movement of the input member to the activated position release the force output member in response to the disk springs.
摘要:
The invention relates to a valve for controlling or regulating flows or pressures of a medium. Said valve comprises a sealing flap that is actuated by a triggering unit. The sealing flap can be placed in the valve chamber of a valve body based on the position of the triggering unit. The sealing flap cooperates with the triggering unit with the aid of a lever which supports at least one sealing seat. The sealing seat is surrounded at least in part by a seal.

The sslenoid valve of this invention comprises an electromagnet with a rotator disposed in at least one side of the valve body. The shaft of the rotator is provided with the valve members to open or close the valve port. The solenoid valve has advantages such as high attraction force, less power, and is easy to continuously control.

Solenoid valve (1) comprising a coil (2) surrounding a guide (3) for an armature (4), the armature (4) being movable in the guide (3) through magnetising of the coil (2) or by means of a return mechanism (5), and a valve seat (6) co-operating with a closing member (7) for selective opening or closing of a valve opening (8) through the valve seat (6) controlled by the armature (4) movement. As the closing member (7) is a separate device in relation to the armature (4), which closing member is activated by the armature (4) movement to a rocking movement around a contact point with the valve seat (6), an N.O. or N.C. solenoid valve of a simplified construction is obtained.
摘要:
Mechanical transmission elements (14) having substantially a cylindrical shape, whose periphery is substantially triangular and whose edges are rounded off, are used to transmit the displacement of an actuator (1), especially in an injection valve. The large width of the transmission element makes it possible to create flat support areas so that friction is reduced during transmission.

Die Erfindung betrifft ein hydraulisches Mehrwegeventil, insbesondere Lenkartenwählventil für mehrachsig gelenkte Fahrzeuge, mit einem oder mehreren Wege-Sitzventilen (31, 33, 35, 37, 39, 41, 43), die zumindest zwei Schaltstellungen aufweisen und die über Leitungen für das Hydraulikmedium untereinander und mit einer Anzahl gesteuerter Anschlüsse (A, B, C, D; L, R) derart verbunden sind, dass die gewünschten Schaltstellungen des Mehrwegeventils (13) durch die Betätigung der Sitzventile (31 - 43) wählbar sind, und mit einer Betätigungseinrichtung (29) zur Betätigung der Sitzventile (31 - 43), wobei die Betätigungseinrichtung (29) in den Schaltstellungen des Mehrwegeventils (13) rastbar ist.
摘要:
Eine Betätigungseinrichtung für ein pneumatisches Umschaltventil (22, 23, 33) weist einen von einem Magnetantrieb (25, 26, 30) beaufschlagten zweiarmigen Betätigungshebel (1) auf, dessen an der Ventilstange (10) angreifender einer Hebelarm (2) steif und dessen an einem Gehäuseanschlag (21) anliegender anderer Hebelarm (5) elastisch ist. Aus dem steifen Hebelarm (2) ist eine Federzunge (17) herausgetrennt, an welcher der Magnetantrieb (30) angreift und die zugleich als Überhubfeder dient.
