Patent ID: 10732155

Abstract:
A drive module with a hydraulic circuit that includes a reversible motor, a reversible pump driven by the reversible motor, a hydraulic reservoir, a first conduit coupling a first inlet/outlet of the reversible pump to the hydraulic reservoir, a second conduit coupling a second inlet/outlet of the reversible pump to the hydraulic reservoir, first and second hydraulic cylinders, and first and second one-way valves. The first hydraulic cylinder has a third inlet/outlet that is coupled to the first conduit between the reversible pump and the hydraulic reservoir. The second hydraulic cylinder has a fourth inlet/outlet that is coupled to the second conduit between the reversible pump and the hydraulic reservoir. The first one-way valve is disposed in the first hydraulic conduit between the first hydraulic cylinder and the reservoir. The second one-way valve is disposed in the second hydraulic conduit between the second hydraulic cylinder and the reservoir.
