Patent ID: 8726650

Claim:
A hydraulic manifold pump comprising: a housing having a first hydraulic circuit and a second hydraulic circuit, wherein the first hydraulic circuit comprises a first check valve, a first pilot valve, and a first relief valve and the second hydraulic circuit comprises a second check valve, a second pilot valve, and a second relief valve, and wherein both the first and second hydraulic circuits are connected to a fluid reservoir for venting; a bidirectional motor connectable to the first hydraulic circuit and the second hydraulic circuit; a hydraulic actuator connectable to the first hydraulic circuit and to the second hydraulic circuit, the hydraulic actuator having a first hydraulic chamber and a second hydraulic chamber; and the bidirectional motor capable of activating the first hydraulic circuit when the motor is operated in a first direction, and capable of activating the second hydraulic circuit when the motor is operated in a second direction; wherein when the first hydraulic circuit is operated in the first direction, a first fluid portion flows through the first check valve to the first hydraulic chamber and a second fluid portion flows to the second pilot valve, wherein the second pilot valve is configured to activate the first relief valve at a first activation pressure.
