ELECTRO-HYDRAULIC ACTUATOR HAVING END CAP WITH SPLIT BUSHING
摘要:
An electro-hydraulic actuator includes a hydraulic pump, an electric motor operable for driving the hydraulic pump, a piston/rod assembly that is movable in response to fluid from the hydraulic pump, and a housing. A portion of the housing defines a cylinder bore within which a piston of the piston/rod assembly is located. The electro-hydraulic actuator also includes an end cap for closing an end of the cylinder bore and through which a rod of the piston/rod assembly extends. The end cap includes a bushing for supporting movement of the rod through the end cap. The bushing has an axially extending split and is adapted to be under compression when installed in the end cap.
