Abstract:
A switchable support element (1) for a valve train of an internal combustion engine, said support element (1) having an outer housing (2), an inner element (7), a hydraulic clearance compensation element (11) and a coupling means (22), the outer housing (2) being installed with an outer peripheral surface (3) in a reception (4) of a cylinder head (5) and comprising a longitudinal bore (6) within which, in an uncoupled state, the inner element (7) is axially displaceable, the inner element (7) comprising a further bore (9) in which a pressure piston (10) having a head (15) and forming a part of the clearance compensation element (11) is received, said coupling means (22) comprising at least one bore (16, 17) extending in radial or in secant direction in each of the inner element (7) and the outer housing (2) and at least one associated slide (23), said bores (16, 17) being aligned to each other in a relative position of the inner element (7) and the outer housing (2), and the slide (23) being partially displaceable by an actuating means (24) from the bore (17) of the outer housing (2) into the bore (16) of the inner element (7) for achieving coupling, characterized in that the bore (16) of the inner element (7) is made as a pocket bore whose longitudinal axis intersects the further bore (9) of the inner element (7).
