Electromagnetic valve with non-return valve

The valve seat of the non-return valve (30) is an annular surfaces (45, 46) where the central pressure medium passage (33) of the solenoid valve lies. Around the annular surfaces (45) at the side of the non return valve seat, passages (47) for the pressure medium discharge. The sealing lips (43) of the annular plug (41) between the solenoid valve passage (33) and those of the non-return valve, are directed radially inwards and engage the annular surfaces (45) on the valve seat side.
