摘要： A flow measuring apparatus of an embodiment is provided than comprises a cylinder and a piston movable in the cylinder between first and second positions. The piston divides the cylinder's interior area into first and second portions. A biasing member urges the piston toward the first position. A first fluid passageway allows fluid to bypass the piston, and a second fluid passageway is in fluid communication with the first fluid passageway and with the first portion of the cylinder. The second fluid passageway provides fluid to the first portion of the cylinder to move the piston toward the second position. A flow diverter is movable between a first flow position that allows fluid to pass through the first fluid passageway to the outlet and a second flow position that causes fluid to flow into the second flow passageway and into the first portion of the chamber. A retention mechanism is moveable to move the flow diverter to the closed position and is moveable to allow the flow diverter to move to the open position when the piston reaches the second position.

摘要： In one embodiment, a constant-flow valve assembly is provided that comprises a first fluid passageway carrying fluid at a first fluid pressure, a piston chamber, and a second fluid passageway connected to the chamber and carrying fluid at the second fluid pressure. A third fluid passageway is configured to carry fluid at a third fluid pressure. An adjustable valve member is provided between the chamber and the third passageway to provide constant fluid flow to the third passageway. An adjustable restrictor assembly is positioned between the first and second fluid passageways. An inlet portion of the restrictor assembly receives fluid at the first fluid pressure and directs the fluid to a restrictor. An outlet portion receives fluid from the restrictor and directs the fluid to the second fluid passageway at the second fluid pressure. The restrictor is movable to adjust the position of entry and exit portions relative to the inlet and outlet portions to adjust a fluid flow rate through fluid pathway to the second fluid passageway, thereby adjusting the flow rate through the valve assembly.
摘要翻译：在一个实施例中，提供了恒流阀组件，其包括在第一流体压力下承载流体的第一流体通道，活塞室和连接到所述室并在第二流体压力下承载流体的第二流体通道。第三流体通道构造成在第三流体压力下承载流体。在腔室和第三通道之间提供可调节的阀构件以提供恒定的流体流向第三通道。可调式限流器组件位于第一和第二流体通道之间。限流器组件的入口部分接收处于第一流体压力的流体并将流体引导至限流器。出口部分接收来自限制器的流体并且在第二流体压力下将流体引导到第二流体通道。限流器可移动以调节入口部分和出口部分相对于入口部分和出口部分的位置，以调节流过第二流体通道的流体流体的流体流速，从而调节通过阀组件的流速。
