CUP SHAPE CASING FOR HYDRAULICALLY AUTOMATIC ADJUSTABLE COMBUSTION ENGINE

Japanese Patent JPS60222514

A

A cup-shaped casing of a self-adjusting hydraulic tappet for overhead camshaft internal combustion engines, the casing comprising a hollow cylindrical outer part (1) closed at one end by an end member (3) and disposed concentrically therein a hollow cylindrical inner element (4) sealingly connected at its end distal from end member (3) to the bore of the outer part (1) by an annular flange (5), the actual clearance-compensating element (9) being guided in inner element (4) and having around it an annular oil reservoir (10) bounded radially by cylinder wall (2) of outer part (1) and bounded axially by end member (3) of outer part (1) and by flange (5), the outer generated surface of outer part (1) being provided with a peripheral groove (7), characterized in that peripheral groove (7) is axially at least as far from end member (3) as the transition between flange (5) and cylinder wall (2) of outer part (1) and an axial groove (11) starts from peripheral groove (7) at at least one place on the periphery and extends to near the oil reservoir (10) or a chamber (14) communicating therewith and its end zone communicates by through bore (12,17) with the oil reservoir (10) or the chamber (14).
