ABSTRACT:
Regeneration valves are useful in directing fluid expelled from a contracting chamber of a hydraulic actuator to its expanding chamber to increase the actuation speed of the actuator. The present remotely controlled regeneration circuit improves the controllability of the regeneration valve by positioning the regeneration valve between the pump and the control valve so that the fluid expelled from the contracting chamber and combined with the pump flow to the expanding chamber passes through and is controlled by the control valve. The regeneration valve is moved to its regeneration position by pressurized fluid from a solenoid valve which can be selectively energized by the operator manually closing a switch mounted to a control lever.
