Abstract:
Engaging and disengaging support element (1) for a finger lever of a valve drive of an internal combustion engine, comprising a hollow cylindrical housing (4) arranged with a first facing side (8) in a receptacle (2) of a cylinder head (3), the housing having a bore with an axially movable inner element (5) located therein, which is spring-loaded against the housing (4) via at least one compression spring (21), a piston having a head (6) that projects beyond a second facing side (7) of the housing (4) adapted to support the finger lever, the housing (4) and the inner element (5) each have at least one bore hole (14, 11), the bore holes (14, 11) are aligned with each other in an axial displacement of the inner element (5) to a position furthest from the first facing side (8), a coupling piston (12) is movably located in at least one of the bore holes (14, 11) and is displaceable into the other bore hole (11, 14) so that the inner element (5) is connected to the housing (4), the compression spring (21) concentrically surrounds at least the largest part of the inner element (5), the compression spring (21) is supported against a spring plate (22) on a first end (23) that faces the head (6), the spring plate (21) being attached near the head (6) on the inner element (5), and the compression spring (21) on its other end (27) that faces away from the head (6), acts against a ring support (16), which is attached to the housing (4).
