SWITCHABLE SUPPORT ELEMENT

摘要

Disclosed is a switchable support element (1) for a valve train of an internal combustion engine, comprising a housing (4), in the bore of which (5) an axially displaceable inner element (7) is located, wherein two coupling slides (9) run in a radial bore (8) of the inner element (7) and can be brought into engagement with a driver surface of the housing (4) in an axially extended position, wherein the extended position is limited by a height stop means (10), which consists of a circlip assembly, which runs peripherally on an annular shoulder (13) of the inner element (7) and which, in the event of contact, lies radially externally above the upper annular end face (14) thereof in abutment against a lower annular edge (15) of an annular groove (16) of the housing (4) near the upper edge thereof (17), and wherein an outer casing (11) of the housing is enclosed by a rotationally fixed ring as an outer anti-twist mechanism (12) with an offset bore (18).
