Abstract: A double-rod electrohydraulic actuator for the purpose of causing push-pull motion while being part of a structure. Actuator comprises of a piston assembly and an external cylinder. Piston assembly comprises of a piston housing and flanged piston rods on both ends. Piston housing comprises of a cylindrical housing with external sliding seals in sealing contact with the interior surface of the external cylinder. Cylindrical housing contains: pump, motor, relief valves, seals, and porting required for control of fluid flow through the assembly. External cylinder will have sliding seals at both ends in sealing contact with the flanged piston rods of the piston assembly, and hydraulic fluid filling all internal voids. The flanged piston rods will have porting in the flanges for fluid flow and hollow centers for wiring conduit to and through actuator. Relief valves will bypass fluid around the pump section in overload conditions to protect the actuator.
