    摘要: A switchable component, which has a housing with a bore and an inner element held in the bore with a head that projects above a rim of the housing. The housing and the inner element are loaded away from each other by a lost-motion spring. At least one coupling piston sits in an opening of the inner element. Sections of the coupling piston are moveable over a ring surface to a carrier surface of the housing. A retaining ring packet has a circular arc-shaped outer surface that lies in a ring groove of the bore of the housing. A ring face of the inner element sits against the underside of the retaining ring packet in the extended state defining relative position. The retaining ring packet, starting from at least one of the surfaces of the retaining ring packet has recesses for forming tab-like sections lying circumferentially between the recesses.

    摘要: A coupling device (1) of a switchable cam follower (2), in which a borehole (9) extends above a contact (8) for a support element in an outer lever (3) of the cam follower (2), and this borehole has a first section (10) of large diameter that starts from an outer side (11) of a crosspiece (6) on the other end (7) to which connects to a second section (12) of accordingly smaller diameter up to directly before an inner side (13) of the crosspiece (6). A smooth cylindrical coupling slide (14) is guided in a sealing manner through the second section (12), and this coupling slide projects with a sub-region (15) into the first section (10). This sub-region (15) is encompassed by a compression spring (16) that acts, on one end, against an annular end (17) formed between the sections (10, 12) and, on the other end, against a catch element (19) arranged on the lateral surface (18) of the sub-region (15). The first section (10) is closed by a thin-walled plug (20), such that a pressure space (22) for hydraulic medium is located axially between the annular end (17) of the borehole (9) and an inner side (21) of the plug (20), and for a coupled case, the coupling slide (14) can be brought into contact by hydraulic medium that can be guided into the pressure space (22) before its outer end (23) with a sub-region (25) extending on its inner end (24) with a catch surface (26) of a cross region (27) of the inner lever (4) and, for a decoupled case, the coupling slide (14) can be displaced in the direction toward the plug (20) such that it is out of contact from the catch surface (26) for a switched-off/reduced hydraulic medium pressure via the compression spring (16).
