摘要： The invention proposes a subassembly of a hydraulic variable valve train of an internal combustion engine, having a guide bushing (4) that can be installed in a hydraulic housing (3), and having a piston (5) supported therein so as to be axially movable for actuating a gas exchange valve (1), and having a valve element (7) that, together with the end face (10) of the piston distant from the gas exchange valve, defines a hydraulic pressure chamber (11) in the guide bushing, wherein the valve element is a throttle check valve that allows hydraulic medium to flow out of the pressure chamber throttled by a continuously open throttle opening (16) and allows hydraulic medium to flow into the pressure chamber with little throttling by a ball check valve (17). The subassembly is intended to be implemented as a modular unit assembled outside of the hydraulic housing, wherein the guide bushing and the valve element are fastened to one another, and the piston is secured in a captive manner in the guide bushing.

摘要： An electromagnetic valve, which has a magnet armature chamber, a pressure medium chamber, a pressure medium inlet channel and a pressure medium outlet channel respectively connected to the pressure medium chamber, a valve seat, and a valve closure member that, upon bearing contact on the valve seat, blocks the connection between the pressure medium inlet channel and the pressure medium outlet channel, and a valve guide extending between the magnet armature chamber and the pressure medium chamber. A sealing ring made of a polymer, which surrounds the valve closure member and separates the magnet armature chamber from the pressure medium chamber, extends between the valve closure member and the valve guide. The geometric design of the sealing ring to the valve guide provides wear resistance for the sealing ring.
