摘要： A valve (22) includes a first diaphragm (48) for opening and closing a fluid flow path between an inlet port (44) and an outlet port (46). A second diaphragm (50) cooperates with the first diaphragm to enclose a chamber (52) formed within the valve body. The valve is closed by applying an actuating pressure to an exterior side of the second diaphragm to move the first diaphragm to the closed position.

摘要： The present disclosure relates generally to a valve assembly including a valve body (44) and a poppet member (54) for controlling flow through the valve body. The valve assembly also includes a valve seat (58) adapted to interface with the poppet member to provide a fluid seal, and seat retaining member (60) adapted to be compressed against the valve seat. Additionally, the valve assembly includes a deformable elastic spacer (62) arranged and configured to axially compress the valve body and the seat retaining member together such that relative movement between such components is inhibited.

摘要： A diaphragm pump is provided having a plurality of piston inlets connecting a hydraulic fluid source with the piston chamber and a plurality of check valves each having a ball and valve seat disposed within the inlets. The valve seat includes a conical section sloped such that the tangential contact point between the ball and valve seat is located at a position outward from the inner edge of the valve seat. The distance the ball is permitted to move between the open and closed positions is such that the check valve closes substantially in conjunction with the piston beginning its power stroke and the ball is not able to generate a high closure velocity. A diaphragm plunger includes a spherical surface portion designed to impact a diaphragm stop at a position away from the edges of the stop and plunger. An isolation reservoir is connected to a piston reciprocating chamber such that hydraulic fluid completely fills the piston reciprocating chamber and further flows into the isolation reservoir. A sliding valve includes a housing which has at least one elongated slot to permit the flow of hydraulic fluid into the piston chamber.
摘要翻译：提供隔膜泵，其具有将液压流体源与活塞室连接的多个活塞入口和多个止回阀，每个止回阀具有布置在入口内的球和阀座。阀座包括锥形部分，该锥形部分倾斜成使得球体与阀座之间的切向接触点位于阀座内边缘外侧的位置处。球允许在打开和关闭位置之间移动的距离使得止回阀基本上与活塞开始其动力冲程一起关闭，并且球不能产生高关闭速度。隔膜柱塞包括球形表面部分，该球形表面部分设计成在远离止挡和柱塞的边缘的位置处撞击隔膜止挡件。隔离储存器连接到活塞往复室，使得液压流体完全填充活塞往复室并进一步流入隔离储存器。滑阀包括壳体，该壳体具有至少一个细长槽以允许液压流体流入活塞腔室。
