ABSTRACT:
The coil arrangement of an electromagnetic valve has a stationary core that is provided with a stop face for having one end of an armature abut thereagainst. The stop face and the one end of the armature is located in a damping chamber, the other end of the armature mounting a closure member for abutting against a valve seat to block fluid flow therethrough. Between the armature and the guide member there is a throttle path that fluidly connects the damping chamber with the valve seat chamber. The electromagnetic valve is especially suitable for conveying contaminated media.
