Abstract

A switchable, hydraulic support element (1) requiring only a small design space is proposed. For achieving this, a bore (16) for a slide (23) is arranged laterally of a pressure piston (10) of a hydraulic clearance compensation element (11) in the inner element (7) 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 (23) is installed in a housing (19) that extends in the cylinder head (5).
