Electromagnetic valve

Abstract

An electromagnetic valve has an armature, a plunger connected with the armature, a spring-biased valve body on which the plunger acts, a non-magnetic flange sleeve which guides the armature, a coil, a magnetic pole disc located opposite to the flange sleeve relative to the armature and attracting the armature with the plunger, the non-magnetic flange sleeve and the magnetic pole disc being interchangeable, and a spring which acts upon the armature, and is supported against the pole disc. The armature, the pole disc and the flange sleeve are formed so that by changing their position the electromagnetic valve can be converted from a currentless open electromagnetic valve to a currentless closed electromagnetic valve, and vice versa in that the pole disc can be located closer to the valve body and the flange sleeve can be located farther from the valve body so that the electromagnetic valve is converted to a currentless open electromagnetic valve, the flange sleeve can be located closer to the valve body and the pole disc can be located farther from the valve body so that the electromagnetic valve is converted into a currentless closed electromagnetic valve.
