Abstract (en)
[origin: US4729350A] A hydraulic valve clearance compensation apparatus for internal combustion engines comprising a hydraulic compensation element accommodated in a bore of a rocker arm or actuating element which bore extends in prolongation of the stem of a motor valve and having a piston element guided for longitudinal displacement and provided with a crowned projection at its end facing the valve stem wherein a guide shoe is arranged between the crowned projection and the flat end face of the valve stem which, on the one hand, includes a spherical indentation engaged by the crowned projection of the piston element and, on the other hand, has a flat surface supported by the end face of the valve stem wherein the guide shoe is securely mounted to the valve stem, characterized in that a cage element (13) is arranged at the valve stem (4) or at an element (b 7,8) connected to the latter, the cage element (13) extending in direction to the piston element (3) and ends in radially inwardly directed restraining zones (15,19,23) which encompass the outer surface of the guide shoe (9) or projection (12) of this outer surface so that the guide shoe (9) is freely displaceable in the transverse direction relative to the valve stem (4) but is stil securely mounted thereto.
