摘要: Control of the displacement of a variable displacement pump is achieved by the use of a standard opencenter type of control valve and pump displacement controls that include a sensor valve. The control functions that are achieved include system standby at low pressure and minimum displacement thereby minimizing power loss and heat rise.

摘要: A hydraulic system comprising a plurality of working circuits each including a control valve and a fluid motor, a control signal pressure is selected from a working pressure of one or more working circuits; and this control signal pressure is applied to a valve that is effective to modify the operation of one of the working circuits. The hydraulic system includes a priority valve incorporated into well-known Delta P valves for applications to hydraulically-controlled equipment, such as shovel loaders, the priority function being desirable in this connection to provide pressure or flow priortiy to the bucket cylinders while the bucket is being filled.
