Beschreibung
Zusammenfassung:	An electromagnetically actuated, quick-action hydraulic switching valve has a pressure-balanced seating valve arrangement and an electromagnetic actuator means. The electromagnetic actuator means comprises a core and an armature for actuating the valve, the core and the armature defining a working air gap. The armature is part of the core and is in the form of a sleeve member mounted slidably on a guide pin which is pressed in position in the housing. The seating valve arrangement is formed by an annular edge defined by a central bore in the armature on the one hand and on the other hand, either a taper surface on the guide pin or a ball with a bore therethrough. Using the same armature, the valve can be designed to operate either as a valve which is open in the currentless condition or as a valve which is closed in the currentless condition.
