Abstract
An annular insert disposed at one end of a hydraulic cylinder and embedded in the material of the cylinder housing during molding of the housing. The insert has an internal groove in which a conventional retainer and abutment member in the form of an elastic spring steel split ring is engaged, whose function it is to act as a direct abutment preventing the piston disposed reciprocably in the cylinder from being pushed out of the open end of the cylinder, in some structures. In other structures the annular insert acts directly as a retaining member for the end of a sleeve installed in the cylinder housing, or indirectly through the intermediary of an end cap.
