<p>A differential pressure actuated bypass valve for use in a load-responsive hydraulic system for controlling a fluid actuated device including at least one manual control valve wherein said bypass valve is adapted to bypass excess fluid at a low differential pressure when no fluid is being directed to a fluid motor. The bypass valve including valve means actuatable to adjust the bypass valve to bypass fluid at a higher differential pressure when a fluid motor is actuated to extend the flow capacity of the manual valve and to provide a connection between the pump and the fluid motor through the pilot or control circuit initially.</p> |
