摘要： A hydraulic circuit is disclosed. The hydraulic circuit may have a variable displacement pump. The variable displacement pump may have a fluidic displacement control configured to vary a flow of pressurized fluid based on a fluid signal and an electronic displacement control configured to vary the flow of pressurized fluid based on an electronic signal. The flow of pressurized fluid may be controlled by the one of the fluidic and electronic displacement controls that requests the smallest flow of pressurized fluid. The hydraulic circuit may also have a control valve connected between the pump and the fluidic displacement control, and the control valve may be configured to transmit the fluid signal to the fluidic displacement control. The hydraulic circuit may further have a controller configured to transmit a fluid signal to cause the fluidic control to request a maximum flow of pressurized fluid, and transmit an electronic signal requesting a flow smaller than the maximum flow, which causes the electronic displacement control to vary the flow of pressurized fluid.

摘要： This disclosure provides for pressure limiting a hydraulic system to a desired pressure value by a particular circuit by controlling and closing the compensator when the desired pressure setting is achieved. Closing the compensator will reduced the pressure head and flow in the circuit resulting in improved efficiency. One illustrated embodiment of the disclosure provides a relief valve in the pilot signal for a compensator. The method relates to limiting the pressure on an open side of the compensator, such that the pressure on the other side closes the compensator thereby limiting the pressure and also flow in the hydraulic circuit. In other words, the pressure on the open side is limited by the relief valve. Thus, the pressure on the other side increases thereby regulating the flow and pressure through the compensator.In another embodiment of the disclosure, instead of reducing the pressure on the open side, the pressure on the closed side is increased, thereby controlling the flow and pressure of the hydraulic circuit. The pressure can be increased by a pump or any other suitable mode.
摘要翻译：本公开提供了当实现期望的压力设定时通过控制和关闭补偿器，通过特定电路将液压系统限制到期望的压力值。关闭补偿器将减少电路中的压头和流量，从而提高效率。本公开的一个示出的实施例提供了用于补偿器的导频信号中的安全阀。该方法涉及限制补偿器的开放侧上的压力，使得另一侧的压力关闭补偿器，从而限制压力并且还在液压回路中流动。换句话说，开放侧的压力受到安全阀的限制。因此，另一侧的压力增加，从而调节通过补偿器的流量和压力。在本公开的另一实施例中，代替减小开放侧的压力，增加了封闭侧的压力，从而控制液压回路的流量和压力。可以通过泵或任何其它合适的模式来增加压力。
