| 摘要 |
A versatile load sensing hydraulic system capable of being adapted to a variety of possible configurations for vehicle mounted implements such as plow/spreader type vehicles or the like is disclosed. An embodiment of the hydraulic system comprises a reservoir means for hydraulic fluid; a load sensitive variable displacement pump means for pumping hydraulic fluid from the reservoir; and a plow on/off valve means having a pressure port coupled to the pump means for receiving hydraulic fluid under pressure. The plow valve means includes a manifold means having a fluid channel coupled to the plow valve means pressure port and further having a number of return ports; one or more on/off valve means coupled to the manifold means return ports, each valve means being adapted to control fluid flow therein to operate a respective component of the plow equipment; and a stroke valve means coupled to a manifold means return port, the stroke valve means being adapted to operate in conjunction with one or more of the on/off valve means for providing a load sensing pressure signal to the pump means.
