摘要:
A double acting actuator is used for operating a pair of latches, and is controlled through a manifold that will permit a base end of the actuator to remain under pressure, and accommodate valve and piston leakage by connecting the rod end of the actuator to drain through a small orifice. The manifold additionally has relief valves for providing different pressures for the rod and base ends of the actuator, and a flow divider that provides a low flow to the actuator while the main flow from a pump is used for other hydraulic components.
摘要:
A hydraulic pressure control system having a variable displacement pump fluidly connected to a hydraulic motor. The pump provides flow to a first circuit upon demand. Remaining flow is provided to a second circuit. The second circuit includes a pilot controlled pressure reducing valve that adjusts the pumps outlet pressure based upon a sensed loads taken from a conduit between the pressure control valve and an active flow regulator valve.
