方のポンプの吐出油を一方のポンプの吐出油と合流させ
る関係にし。 た油圧駆動回路。[Claim for Utility Model Registration] Out of two pumps, one pump is always connected to a control valve that communicates with the techetater, while the other pump is connected to a switching valve. The load position is maintained, and when the discharge pressure of the one pump becomes equal to or higher than the set pressure, it is sensed and activated to cause the discharge oil of the other pump to merge with the discharge oil of the one pump. Hydraulic drive circuit.
