ABSTRACT:
An inner element for a hydraulic valve clearance compensation element for internal combustion engine comprising a cylindrical element (3) closed on one end and a piston element (5) guided therein for longitudinal displacement and protruding beyond the open end of cylindrical element (3), the piston element (5) having a reduced outer diameter (6) in its protruding portion engaging a radial flange (10) of a restraining element (9) held by a collar (13) on the open end of cylindrical element (3), the open end of element (3) having also a reduced outer diameter (7) with an additional diameter reduction in the form of peripheral groove (8) engaging positively the collar (13) of the restraining element (9) at at least some peripheral points, the restraining element (9) having one projection (11) at at least one peripheral point radially protruding beyond the outer diameter of cylindrical element (3), characterized in that the collar (13) of restraining element (9) is provided in its initial stage so its cylindrical external contour does not exceed the outer diameter of cylindrical element (3) and in the area of the collar (13) indentions are provided at at least two positions about the circumference at which the restraining element material is shaped into the peripheral groove (8) of the cylindrical element (3) whereby collar (13) displays an enlarged diameter at the circumference portion situated between the indentations so that it exceeds the outer diameter of the cylindrical element there.
