ABSTRACT:
An electromagnetically operated pressure switching valve has a valve housing, a magnet coil arranged inside the valve housing, a magnet core associated with the magnet coil and having a passage for a pressure medium provided with a valve seat, a magnet armature, a valve closing element arranged in the valve housing for controlling a flow of the pressure medium. The magnet armature has a portion extending in the magnet coil to an area of a greater magnetic flux density. The portion of the magnet armature cooperates with the valve seat of the passage and is limited by a ring-shaped circular flange-like edge extending outside of the magnet coil.
