Abstract

An electromagnetic switching valve for use in an internal combustion engine has a coil housing containing an electrical coil, and a value housing containing a valve plate for selectively opening and closing an opening in the housing through which a medium can flow from an inlet to an outlet thereof. An armature is in operative association with the coil electrical coil for undergoing longitudinal movement in the housing depending upon energization of the coil, and the armature acts on a rod movable with the armature. The rod is radially guided during movement thereof, and the rod is connected by a ball and socket joint to the valve plate. The rod is engaged with the armature within the coil housing for longitudinal movement therewith without any radial connection therebetween. The valve housing which containins the valve plate can be inserted in a surrounding connection housing which may contain a filter and elastic valve elements for pressure control.
