摘要： An independent metering valve (IMV) assembly is disclosed that includes a metering stem including an inlet. The IMV assembly also includes a hydro-mechanical control valve in communication with a fluid source and the inlet. The control valve also including a spool with a closed end and an open end. The control valve includes a biasing member that biases the control valve or spool towards an open position thereby establishing communication between the fluid source and the inlet. The control valve also including a load signal line providing communication between an outlet of the control valve upstream of the inlet and the closed end of the spool. Wherein high pressure in the load signal line allowing the control valve to move towards a closed position thereby overcoming bias of the biasing member and reducing flow to the inlet during a high pressure condition.
摘要翻译：公开了一种独立计量阀（IMV）组件，其包括包括入口的计量阀杆。 IMV组件还包括与流体源和入口连通的水力机械控制阀。控制阀还包括具有封闭端和开口端的线轴。控制阀包括偏压构件，该偏置构件将控制阀或阀芯朝向打开位置偏置，从而建立流体源和入口之间的连通。控制阀还包括负载信号线，其提供在入口上游的控制阀的出口与阀芯的封闭端之间的连通。其中负载信号线中的高压允许控制阀朝着关闭位置移动，由此克服偏置构件的偏压并且在高压条件期间减少到入口的流量。

摘要： A control system for a machine is disclosed. The control system may have a pump, a low pressure reservoir, and at least one actuator connected to receive fluid pressurized by the pump and discharge fluid to the low pressure reservoir. The control system may also have a bypass passage situated to allow fluid to bypass the at least one actuator, and a warmup valve disposed within the bypass passage and being movable between a flow-passing position and a flow-blocking position. The control system may further have a hydraulic temperature sensor configured to generate a signal indicative of a temperature of the fluid, and a controller in communication with the pump, the warmup valve, and the hydraulic temperature sensor. The controller may be configured to move the warmup valve to the flow-passing position, fix a displacement position of the pump, and adjust an input speed of the pump in response to the signal.
