<p>An electromagnetic valve having an armature isolated from the flow of pressure medium and a valve actuated by the armature via a push rod. The armature is variously excitable at various current intensities (i1, i2) and is accordingly capable of assuming three different positions. In this manner, a three-position magnetic valve is created which in its neutral positions keeps open a flow of pressure medium to a consumer while closing a leakage conduit. In its second position, the valve closes off the consumer, and in its third position it connects the consumer with a return flow conduit. The electromagnetic valve is usable preferably in anti-wheel-locking apparatuses in motor vehicles.</p> |
