Patent ID: 8776750

Claim:
An assembly for a valve train of an internal combustion engine, comprising: a hydraulic supporting element having a cup-shaped housing and a pressure piston, the cup-shaped housing has a bore and a duct for a hydraulic medium, the pressure piston has an outer shell with an end face, at least one passage and a storage space, the pressure piston runs via the outer shell in the bore of the cup-shaped housing, and the hydraulic medium can be guided via a channel between the housing and the pressure piston to the at least one passage in the pressure piston to the storage space in the pressure piston; and a drag lever, which is seated at one end, via a bearing face that is situated in an underside of the drag lever, on the end face of the pressure piston that is complementary to the bearing face of the drag lever, wherein the bearing face of the drag lever contacts the end face of the pressure piston with a direct contact region, and the pressure piston is installed in a manner which is rotationally oriented in a defined way with respect to the drag lever, the direct contact region being configured to provide and anti-rotation safeguard so that the pressure piston remains rotationally oriented in the defined way with respect to the drag lever wherein the housing is rotationally movable with respect to the pressure piston.
