Switchable tappet for the direct transmission of a cam lift to a tappet push rod

A switchable tappet for a direct transmission of a cam lift to a tappet push rod in a valve train of an internal combustion engine, said tappet comprising a housing in whose axially extending cavity a longitudinally displaceable inner element is arranged that an be connected to the housing, in a relative position to the housing, by a coupling means, said housing comprising on an end facing away from the cavity, a contact surface for a cam, and the inner element comprising on a side of the cavity, a support for the tappet push rod, which inner element extends beyond the cavity by an extension and is biased way from the housing by at least one coiled compression spring,

• the coiled compression springs arranged at least substantially around the extension of the inner element and acts at one end on a support of the inner element facing away from the cavity and at another end against a section of the cavity near the edge the extension of the inner element is made as a separate component out of thin-walled light-weight material and is connected to one of an outer peripheral surface and an inner peripheral surface on the outside of the inner element by a clip or snap connection and starting from the edge, the cavity of the housing comprises a radially inwards stepped configuration so that the section near the edge is an annular shoulder situated within the cavity.
