Switchable support element

摘要

A switchable support element (1) for a valve train of an internal combustion engine is disclosed, including 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 (10), which is formed 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 (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).

主权项

1. A switchable support element for a valve train of an internal combustion engine, comprising a housing that is installable in a receptacle of a cylinder head of the internal combustion engine having a bore hole in which an axially moving inner element is located that receives a force applied by a spring element pushing said inner element outward from the housing, at least one coupling slide runs in a radial bore hole of the inner element, said at least one coupling slide is brought into engagement in an axially extended position of the inner element with a driving surface of the housing, and the axially extended position is limited by a height stop, a projection extends past an outer casing of the housing to form an outer anti-rotation lock, the height stop includes at least one circlip that surrounds an annular shoulder of the inner element and contacts a lower annular edge of an annular groove of the housing at an upper edge thereof radially outward past an upper annular end in the contact case, and the outer casing of the housing is surrounded by a rotationally fixed ring or ring segment as the outer anti-rotation lock with an offset bore hole for installation in a complementary counter contour of the receptacle of the cylinder head.
