Abstract

An assembly for a valve train of an internal combustion engine, which has a hydraulic support element and a cam follower resting on one end via a bearing surface located on the bottom side thereof on a complimentary end side of a pressure piston of the support element. The piston extends across the outer shell in a bore of a crucible-shaped housing of the support element. The housing has an opening for hydraulic fluid, which is conductible via a channel between the housing and piston through a passage in the pressure piston to a storage chamber. In a section of a direct contact region between the bearing surface of the cam follower and end side of the piston, an anti-turn mechanism for the piston in relation to the cam follower is implemented. The piston is installed in a defined manner and is torsionally oriented in relation to the cam follower.
