摘要： A differential dry pipe valve is provided having a body including an inlet chamber having an inlet port, an exit chamber having an exit port, and a gasket flange positioned between the inlet and exit chambers facing the exit port, the inlet and exit ports being substantially aligned. The valve also includes a gasket attached to the gasket flange and an openable cover hingedly attached to the body. The gasket has an inner water lip in fluid communication with the inlet chamber and an outer air lip surrounding the water lip. The spacing between the water lip and air lip varies. The air and water lips are coaxial. The cover is configured to be sealingly engaged with the seal when in a closed position and to be sealingly disengaged in an open position when the pressure in the exit chamber is lower than the pressure in the inlet chamber. When the cover is in the open position, a direction of a path between the inlet and exit ports is substantially unaltered.

摘要： A flow regulating valve (20) for a diesel engine (11) in which a unitary valve element has three positions for controlling flow from a unit injector fuel injection system in response to valve inlet pressure. The valve (20) has a first position wherein flow is blocked below about 10 psi, a second position between about 10 psi and 20 psi wherein flow is substantially unrestricted, and a third position above about 20 psi wherein flow is restricted to minimize return flow to a fuel supply and minimize fuel cooling requirements.

摘要： A hydraulic power steering system (10) for turning steerable wheels of a vehicle. The system (10) comprises a steering gear (12) including a hydraulic motor, actuatable to turn the steerable vehicle wheels, and a steering valve, for controlling actuation of the hydraulic motor by controlling fluid flow to the hydraulic motor. The steering gear (12) has an inlet (38) in communication with a fluid source and an outlet (40) for directing the fluid from the hydraulic motor back to the fluid source. The steering gear is susceptible to pressure fluctuations that cause noise during steering. The system (10) further comprises a pressure relief valve (14) having an unactuated condition and actuated conditions. The pressure relief valve (14), in the unactuated condition, restricts fluid flow through the pressure relief valve (14). In an actuated condition, the pressure relief valve (14) permits fluid flow through the pressure relief valve (14). The pressure relief valve (14) progressively moves from the unactuated condition to an actuated condition as a pressure differential between the inlet (38) and the outlet (40) of the steering gear (12) increases. The pressure relief valve (14), in an actuated condition, providing fluid communication between the inlet (38) and the outlet (40) of the steering gear (12) while circumventing the steering gear (12) to minimize the pressure fluctuations in the steering gear (12).
摘要翻译：一种用于转向车辆的转向轮的液压动力转向系统（10）。该系统（10）包括一个舵机（12），该舵机包括一个液压马达，可驱动转向可转向的车轮;一个转向阀，用于通过控制流向液压马达的流体来控制液压马达的动作。舵机（12）具有与流体源连通的入口（38）和用于将来自液压马达的流体引导回流体源的出口（40）。舵机易受压力波动的影响，导致转向过程中的噪音。系统（10）还包括具有未致动状态和致动状态的减压阀（14）。在未致动状态下的减压阀（14）限制流过压力释放阀（14）的流体。在致动状态下，减压阀（14）允许流体流过压力释放阀（14）。当舵机（12）的入口（38）和出口（40）之间的压差增加时，减压阀（14）逐渐从未致动状态移动到致动状态。压力释放阀（14）处于致动状态，在绕过舵机（12）的过程中提供入口（38）和舵机（12）的出口（40）之间的流体连通，以最小化舵机舵机（12）。

摘要： A piston check valve (10, 20) for use in a system which conveys abrasive materials includes a gland nut (22) which connects the valve to the piping system, a valve body (24) mounted on the gland nut (22), a valve seat (14, 26) mounted on the valve body (24), and a piston (38) mounted within the valve body (24). The piston (38) can translate within the through bore (36) of the valve seat (14, 26) and has a shaft (40) and a head (42) which contacts the first end (30) of the valve seat (14, 26) when the valve is closed. A coil spring (52) is located within the through bore (36) of the valve seat (14, 26) and biases the valve closed. A first O-ring (56) is mounted on the first end (30) of the valve seat (14, 26) and is sufficiently wide to prevent sufficient quantities of chips from becoming lodged within the surface of the inner O-ring (56) to form a hard bridge across the O-ring (56), allowing erosion of the valve sealing surfaces. The first end (30) of the valve seat (14, 26) has an O-ring groove (58) which receives the O-ring (56). A second O-ring (60) can be mounted on the first end (30) of the valve seat (14, 26) at the outer periphery of the valve seat (14, 26).

摘要： A safety valve comprises a valve member (11) which is movable against spring biasing force (12,13) to close under a predetermined flow rate against valve seats (22, 23) and allow only a small bleed through the valve via slots (28). The housing (10) consists of two parts (14, 15) which are adjustably connected together by screw thread (16), which includes a locking nut (30), enabling the valve to be adjusted and set for operation over a range of different flow rates.

摘要： A variable flow control nozzle (50) has a head (52), a tube (54), and a valve (56). The head (52) disposes adjacent an opening (22) and has a screen (60) for passage of fluid flow into and out of the head's (52) interior. The tube (54) extends from the head (52) through the opening (22) and secures the head (52) thereto. A tube passage communicates the interior of the head (52) with the other side of the opening (22). The valve (56) disposed in the passage has a first condition permitting first fluid flow from the passage to the interior of the head and has a second condition permitting second fluid flow from the interior to the passage. The second fluid flow may be greater than the first fluid flow. The tube (54) can have first (70) and second (80) tube members with different internal diameters, and the valve (56) can use a ball (90) movable between positions in the tube members (70,80).
