In a valve train of an internal combustion engine having a switchable support element ( ), the lost motion spring ( ) of the support element ( ) is arranged axially offset next to the support element ( ) while being coupled to an inner element ( ) of the support element ( ) by a crossbar ( ). Due to this externally positioned spring ( ), the support element ( ) requires only a relatively small design space.

Valve train of an internal combustion engine comprising one or more switchable support elements

In a switchable support element ( ) for a valve train of an internal combustion engine, the lost motion spring ( ) of the valve train is made as a torsion spring. This spring is arranged outside of the support element ( ) and only the legs and the arms of the spring engage a housing and a head, respectively. In this way, the support element ( ) requires no substantially larger design space than non-switchable prior art elements, particularly in axial direction.

Switchable support element

A switchable support element ( ) requiring only a small design space. For this purpose, a slide ( ) that serves to couple an inner element ( ) to an outer housing ( ) in the support element ( ) is positioned laterally in a housing ( ) arranged in the cylinder head ( ). At the same time, a bore ( ) in the inner element ( ) for the slide ( ) is made as a pocket bore, the housing ( ) being seated through an annular extension ( ) directly in a bore ( ) of the outer housing ( ). The slide ( ) can be displaced electromagnetically or hydraulically in at least

A switchable, hydraulic support element ( ) requiring only a small design space is proposed. For achieving this, a bore ( ) for a slide ( ) is arranged laterally of a pressure piston ( ) of a hydraulic clearance compensation element ( ) in the inner element ( ) and is configured as a pocket bore. This dispenses with the stacked arrangement of the bore in the inner element and the clearance compensation element on top of each other as seen in prior art. At the same time, the slide ( ) is installed in a housing ( ) that extends in the cylinder head ( ).
