Abstract
A hydraulic lash element compensating assembly mounted in the valve end of a rocker arm or other valve actuating device. The hydraulic last compensating element compensates for any clearance in the engine valve train due to wear and due to thermal expansion. The element includes a self adjusting hydraulic assembly with a cylindrical outer housing having a spherical protrusion on the end facing the valve. A foot is retained by a retainer permanently fixed to the swivel foot and securely attaching the foot to the housing, but allowing angular and rotational movement of the swivel foot relative to the spherical protrusion on the housing. The retainer may be constructed from a thermoplastic material by injection molding or from sheet steel by stamping.
