Abstract
The invention relates to a hydraulic support element for valve drive of a combustion engine, with a pot cylindrical casing and a hollow cylindrical piston guided axially movably therein, the inner end of which is supported via a spring on the bottom wall of the casing, whose outer end projects past the outer margin of the casing and is formed as a hemispherical bearing head, and whose inner space is subdivided by means of a partition element into an axially inner supply-pressure space and an axially outer switching-pressure space.
