A camshaft adjuster () having a locking cover () formed of sheet metal, wherein the locking cover () has a substantially disc-shaped base surface () and has a collar (), which extends in an axial direction () and which runs at least partially around the base surface (), for receiving a spring cover (). As a result of the production of the locking cover () from sheet metal in combination with a turned-up collar (), the locking cover () can be produced simply and cost-effectively and nevertheless offers adequately high strength despite the low material thickness.

Camshaft adjuster

A camshaft adjuster arrangement () having a camshaft () and a rotor () for a camshaft adjuster. The rotor () has a central bore () for a fixing element (), the rotor being mounted on the camshaft () in a rotationally fixed manner by the fixing element (). The mounting of the camshaft adjuster arrangement () is simplified by forming a frictional connection between the camshaft () and the rotor () using a clamping unit ().

Camshaft adjuster arrangement and camshaft adjuster

An electromagnetic hydraulic valve having an electromagnet with a coil winding arranged on a spool, and a magnet housing, a valve stem having a pressure connection, a tank connection and a consumer connection. The spool and the valve stem are a one-piece plastic body which has an axial longitudinal bore which is an armature space for a magnet armature and also is a control region for a closing body. The magnet housing, with a collar which projects into the longitudinal bore, forms a top magnet pole of the electromagnet. A bottom magnet pole, connected to the magnet housing in a magnetically conductive manner, of the electromagnet likewise projects into the longitudinal bore of the plastic body. The bottom magnet pole of the electromagnet is formed by an annular disk which is integrally cast in the plastic body and which, by a plurality of free sections and a plurality of radial webs at its outer circumference, is designed both as an element for fastening the magnet housing to the hydraulic valve and as an element for fastening the hydraulic valve to an engine block of an internal combustion engine.
