摘要：The Invention concerns g solenoid valve, more particularly a proportionalhydraulic valve which is arranged within a hydraulic system of a device for varying the

valve timing of gas exchange valves in an internal combustion engine. The solenoid valve() generally comprises an electromagnet () having a hollow cylindrical magnet housing (),at least one coil winding () and an armature () as Well as a first pole shoe () and a secondpole shoe () and further comprises a valve member () having a hollow cylindrical valvehousing () for receiving a spool valve which is displaceable relative to the valve housing ()by the armature () of the electromagnet (). According to the invention, the electromagnet() and the valve member () are connected and fixed radially and axially to each other byforce locking and/or positive engagement by the second pole shoe () of the

electromagnet () which is arranged adjacent the valve member () and configured as aplug-in lock for the valve housing ().
