    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 switchable component (1) for a valve train of a combustion engine is provided, such as a roller tappet, with a housing (2), in whose borehole (3) an inner element (4) runs that can move relative to the housing in the axial direction. At least one coupling element (6) is allocated to the inner element (4), wherein this coupling element, in the decoupled case, lies with its outer end (7) directly in front of an annular surface (8) between both components (2, 4) and, in the coupled case, engages in some sections with a driver surface (9) in the borehole (3) of the housing (2), and wherein, between the components (2, 4) there is a lost-motion spring element (10) forcing these components away from each other in the axial direction. As the coupling element (6) there is at least one sickle-shaped ratchet that can pivot outward and that sits at least indirectly in an opening (11) in the outer shell (5) of the inner element (4) and that is connected to the inner element (4) in an articulated way at one end (12). An annular groove is present as a driver surface (9) in the borehole (3) of the housing (2) and the coupling element (6) can pivot outward in the coupling direction via the force of a mechanical spring (13) and can pivot inwardly in the decoupling direction via hydraulic medium guided into the driver surface (9) in front of its outer end (7).
