Abstract: A relatively low pressure hydraulic control system for a high pressure work output system in which a control valve is selectively actuated to position a variable displacement axial piston pump to control the flow in the work output system and to position a directional valve which controls the direction of work output. In such a system wherein two work outputs are provided, thereby requiring two control valves, a priority valve may be utilized in the low pressure system so that a signal from one of the control valves will always override a signal from the other control valve in controlling the axial piston pump.
Abstract translation: 一种用于高压工作输出系统的相对低压的液压控制系统，其中控制阀被选择性地致动以定位可变排量的轴向柱塞泵来控制工作输出系统中的流量并且定位控制阀的方向阀 工作输出。 在提供两个工作输出的这种系统中，由此需要两个控制阀，优先阀可以用在低压系统中，使得来自控制阀之一的信号将总是在来自另一个控制阀的信号中控制 轴向活塞泵。
