Abstract

An electromagnetically actuated valve having an adjustable abutment is disclosed. The valve comprises a valve housing and at least one annularly-shaped solenoid coil, which is arranged in the valve housing and which, on its interior peripheral side, surrounds a magnet armature. The armature is capable of axially reciprocal motion with respect to the solenoid coil. The magnet armature is elastically braced in the area of its front end by a spring element that in turn transmits force against an abutment that forms a component of the valve housing. At its other end, the armature is provided with a sealing member that can be forcibly engaged against a valve seat, as needed. The abutment is adjustable relative to the valve housing along the axis of reciprocal axial motion of the magnet armature to enable adjustments to the prestressing of the spring element.
