ABSTRACT:
The present invention is directed to a supply circuit for a hydraulic jack employing two pumps in which a valve is positioned in a pipe which is branched to the delivery pipe of the first pump and is controlled by two jacks supplied by the fluid delivered by the second pump. A constrictor is positioned in the supply system for one of the jacks and another constrictor is placed in the discharge system for the two jacks with the invention being particularly applicable to achieving a stable control circuit for the load relief of the first pump.
