Abstract: A leveling valve (30) is provided, of the type that lets air flow from a pressured source (40) into an airbag (24) and that lets air flow from the airbag to the atmosphere, to maintain a predetermined airbag height, which avoids jacking wherein the height of the airbag repeatedly increases as the vehicle moves over a rough road. A pair of inserts in the leveling valve are selected so the passage of the insert that passes pressured air to the airbag is made significantly smaller in diameter than the passage of the insert that passes air from the airbag to the atmosphere.

Abstract translation: 提供了一种调平阀（30），其使空气从加压源（40）流入气囊（24）并使气体从气囊流动到大气中，以保持预定的气囊高度，这避免了 顶升，其中当车辆在粗糙的道路上移动时，气囊的高度重复地增加。 选择调平阀中的一对插入件，使得将加压空气传递到气囊的插入件的通道的直径明显小于将空气从气囊传递到大气中的插入件的通道。

Abstract: A fluid valve operator for moving a moveable valve element such as a disc (14) that is pressed forcefully against a surface of a valve frame (12). The valve operator includes first and second electric gear reduction motors (22, 24) that each has a movable driving member such as a rack (34, 36) that moves against a handle (20) of the valve element to move the valve element to a connect or disconnect position. Each motor withdraws its driving member from the valve member handle after moving the valve member. A default mechanism (90) moves the valve element handle to a preselected one of the positions, such as the disconnect position, when pressure of a fluid falls below a preselected level.

Abstract: An hydraulic actuator with a housing having two ports (A, C) that selectively receive pressured fluid to move a piston (12) to a forward position (12F) or to a rearward position (12R), wherein the piston can be moved to a third, or neutral position (12N) by applying equally pressured fluid to both ports. A pusher (24) that lies in the same housing cavity as the piston, is pushed forward by pressured fluid applied to the second port (C), and the pusher pushes the piston forwardly. The pusher moves forward until the pusher abuts a housing surface (52), at which point the piston lies in the third position (12N).

Abstract translation: 一种具有壳体的液压致动器，该壳体具有选择性地接收加压流体以将活塞（12）移动到向前位置（12F）或向后位置（12R）的两个端口（A，C），其中活塞可以移动到 第三或中性位置（12N），通过对两个端口施加相等的压力流体。 位于与活塞相同的壳体空腔中的推动器（24）被施加到第二端口（C）的加压流体向前推动，并且推动器向前推动活塞。 推动器向前移动直到推动器抵靠壳体表面（52），此时活塞位于第三位置（12N）。
