摘要： A hydraulic system for a machine is disclosed. The hydraulic system has a source of pressurized fluid and a fluid actuator with a first chamber. The hydraulic system also has a first valve configured to selectively fluidly communicate the source with the first chamber. The first valve further includes a first element movable between a flow passing, at which fluid from the source flows to the first chamber, and a flow blocking position, at which fluid from the source is blocked from the first chamber and a second element configured to selectively drain a control passageway associated with the first element to cause the first element to move. The hydraulic system further has a proportional pressure compensating valve configured to control a pressure of a fluid directed between the source and the first valve dependent upon the pressure of the control passageway.

摘要： A valve has a valve body including a main chamber having a first port and a second port, and a main poppet disposed within the main chamber. The main poppet includes a first surface forming a control chamber within the main chamber. The valve has a first passage communicating the control chamber with the first port, and a second passage communicating the control chamber with the second port. The valve also includes a pilot valve having a pilot poppet for controlling fluid flow from the control chamber to the first port through a third passage, and to the second port through a fourth passage, respectively. The valve may further have a feedback spring coupled between the main poppet and the pilot poppet to provide a force relative to a distance between the main poppet and the pilot poppet.

摘要： PROBLEM TO BE SOLVED: To provide a valve applied to an arbitrary hydraulic system containing a fluid actuator requiring a signal pressure gradually transferred to a compensation valve, and capable protecting a component of the hydraulic system and executing a high responsive pressure regulation providing consistent actuator performance with a simple, inexpensive constitution, wherein the signal pressure gradually transferred reduces pressure serge in hydraulic circuit 22. SOLUTION: The valve for the hydraulic system including a pressurized fluid source, the fluid actuator and a proportional pressure compensation valve is provided. The valve has a bore in fluid communication with the fluid source and the fluid actuator. The valve has a valve element disposed in the bore and movable between a circulation shutoff position and a communication position to selectively bring the fluid source into fluid communication with the fluid actuator. The valve has a valve signal passage disposed in the valve element and in fluid communication with pressurized fluid having the signal pressure indicating pressure supplied to the fluid actuator. The valve further includes first and second orifices disposed within the valve element in fluid communication with the valve signal passage and the bore. The valve signal passage transfers the signal pressure to/from the first and second orifices in liquid communication. The first orifice is brought into fluid communication with the system signal passage by shift of the valve element from the circulation shutoff position to the circulation position before the second orifice. Both the first and second orifices are brought into fluid communication with the system signal passage when the valve element is in circulation position. COPYRIGHT: (C)2007,JPO&INPIT
