Hydraulic system and method for pressure control
A hydraulic system includes a poppet valve control valve having an inlet working port, a function working port, a control chamber, and a poppet valve disposed between the inlet working port and the control chamber. The poppet valve is movable between an open position and a closed position. The hydraulic system further comprises a pilot control valve. Pressure associated with the function work port is supplied to a first side of the pilot control valve and pilot source pressure is supplied to a second side of the pilot control valve. When the pressure in the functional piece working port reaches a set point pressure, the pressure associated with the functional piece working port forces the pilot control valve to reach a position that increases flow restriction between the control chamber and the functional piece working port. The poppet moves in a direction toward the closed position and limits the pressure in the functional member working port to a setpoint pressure.
一种包括提升阀控制阀的液压系统，该提升阀控制阀具有入口工作端口、功能件工作端口、控制室、和布置在入口工作端口与控制室之间的提升阀。提升阀可在打开位置与关闭位置之间运动。液压系统还包括先导控制阀。与功能件工作端口相关的压力供应到先导控制阀的第一侧、并且先导源压力供应到先导控制阀的第二侧。当功能件工作端口中的压力达到设定点压力时，与功能件工作端口相关的压力迫使先导控制阀到达增加控制室与功能件工作端口之间的流动限制的位置，使得提升阀沿朝向关闭位置的方向运动、并且将功能件工作端口中的压力限束为设定点压力。
