ABSTRACT:
An hydraulic system has an hydraulic cylinder connected to a reversible pump by a first fluid line. A check valve assembly is connected in the first line and in a second line extending from the pump to a tank. The check valve assembly has a ball that seats on a conical valve seat to enable flow of fluid from the pump to the cylinder but to prevent flow in the opposite direction. A shuttle member in the check valve assembly is displaced by fluid pressure in the second line when the pump is reversed to unseat the ball and allow flow from the cylinder in the opposite direction via the pump to the tank.
