摘要： A valve for controlling fluid flow in a fluid system is disclosed. The valve includes a housing, a servo spool, and a piston. The servo spool defines a spiral groove and a spiral land. The piston defines an orifice configured to provide flow communication to a supply of pressurized fluid and an orifice configured to provide flow communication to a portion of the fluid system exterior to the valve. The valve further includes a main spool operably coupled to the piston. The main spool is configured to control flow of fluid in the fluid system. The spiral groove and spiral land are configured such that angular displacement of the servo spool results in a force imbalance on the piston, thereby moving the piston and the main spool in one of a first direction and a second direction.

摘要： A valve is provided for a hydraulic system having a source of pressurized fluid, a fluid actuator, and a proportional pressure compensating valve. The valve has a bore in fluid communication with the source and the fluid actuator. The valve also has a valve element disposed in the bore and movable between a flow blocking position and a flow passing position to selectively fluidly communicate the source with the fluid actuator. The valve also has a valve signal passageway disposed within the valve element and configured to be in fluid communication with a pressurized fluid having a signal pressure indicative of pressure supplied to the fluid actuator. The valve further has first and second orifices disposed within the valve element in fluid communication with the valve signal passageway and the bore. The valve signal passageway is configured to communicate the signal pressure with the first and second orifices. Movement of the valve element from the flow blocking position to the flow passing position fluidly communicates the first orifice with a system signal passageway before the second orifice, and fluidly communicates both the first and second orifices with the system signal passageway when the valve element is in the flow passing position.
