摘要： A pressure control valve (20) for an automatic transmission of a motor vehicle comprises a housing (28), a valve gate (32) that is guided in the housing (28) and has a plurality of adjacent sections (34, 36, 38), wherein a first section (34) has a first diameter (D1), a subsequent second section (36) has a second diameter (D2), which is smaller than the first diameter (D1), and a third section (38) adjacent thereto has a diameter equal to the first diameter (D1). The first section (34) has a dedicated supply pressure opening (58), the second section (36) has a dedicated control pressure opening (60), and the third section (38) has a dedicated return flow opening (62). An electromagnetic actuating device (26) acts upon the valve gate (32) in a first effective direction (78) by way of a piston (72) engaging at a first face surface (50) and guided pressure-tightly in the housing (28). An application device (53) acts upon the valve gate (32) counter to the first effective direction (78). It is proposed for the first face surface (50) of the valve gate (32) to adjoin a first pressure chamber (82), and an opposite second face surface (52) to adjoin on a second pressure chamber (80), said pressure chambers being fluid-connected to the control pressure opening (60).

摘要：流量制御弁のスプール12の一端に取り付けられる磁気応答性のターゲット・プローブ31と、スリーブ11の一端に取り付けられるセンサ・ハウジング32とを有する。センサ・ハウジング32はターゲット・プローブ31の侵入を許す内部空間を形成する筒部33を有し、筒部33の周囲には軸方向に所定間隔を空けて配置された第1及び第2のコイルC1,C2が設けられる。プローブ31は、コイルに対する磁気応答性が該プローブの直線位置に応じて一方向に漸次変化する構造を成している。第1コイルC1はプローブ31に感応し、第2コイルC2は感応しないように配されている。第1コイルC1のインピーダンスがプローブ31の直線位置に応じて変化し、第1及び第2のコイルの出力を差動合成することにより、プローブ31の直線位置を検出する。

摘要： A position control system for an implement of a work vehicle. The implement, such as a blade, is operatively connected to a push arm rotatably coupled to a frame of the work vehicle. A hydraulic actuator is operatively connected to the push arm and is configured to adjust the position of the push arm with respect to the frame. A controller generates a control command to adjust the position of the hydraulic actuator to thereby raise and lower the blade. A proportional quick drop valve, coupled to the hydraulic actuator and to the controller, directs a flow of fluid to the hydraulic actuator in response to the operator control command. The proportional quick drop valve reduces a drop speed of the blade, reduces cavitation of the actuator valves, and also reduces the pressure drop and fluid flow forces acting on the spools of the actuator valves.

摘要： An injection molding apparatus including:a valve pin driven by an actuator, the valve pin extending axially through at least a portion of the channel length of the fluid flow channel, the fluid flow channel including a throat, downstream flow of the injection fluid being restricted by a bulb portion of the pin, the valve pin having an intermediate position where downstream flow of injection fluid is unrestricted and a fully downstream position where downstream flow of injection fluid is stopped at both the gate and at the throat, wherein the actuator is driven by a valve assembly comprised of a spool mechanically driven by first and second actuators or solenoids that each separately engage the spool at opposing axial ends to effect movement of the spool back and forth between the drive fluid flow positions.
