ABSTRACT:
A compact self-compensating hydraulic lash adjuster (tappet) particularly suited for use in internal combustion engines having overhead cams. A flexible rubber member forms a one-way valve and seal thereby creating a reservoir of hydraulic fluid. This reservoir instantaneously provides the necessary hydraulic fluid for proper tappet operation, even after sustained periods of engine shut-down. A hydraulic compression chamber is contained in a piston assembly positioned within the center of the overall tappet assembly. This construction facilitates the substitution of piston assemblies of varying axial dimension thereby permitting the basic structure to be used in engines having differing tappet length requirements.
