摘要:
A magnetic valve has a valve chamber having at least one valve opening, a valve member adapted to close and to release the at least one opening in its abutment position, an actuating element displaceable between two end positions in the valve chamber and actuating the valve member, a permanent magnet associated with the actuating element and holding the actuating element in the end positions. The permanent magnet is magnetized in a direction of displacement of the actuating element and has two ends extending transversely to the displacing direction and provided with pole pieces. An electromagnet produces a magnetic force which displaces the actuating element between the positions, and the electromagnet has a magnetic core with three parallel legs connected by a transverse yoke and including two outer legs connected with end stops in magnetically conductive manner and a central leg extending to the actuating element and also having an operating winding arranged on the central leg. The pole pieces in association with the central leg of the magnetic core and the end stops are formed so that alternatingly in each abutting position of the actuating element one pole piece abuts without gap against the central leg while another pole piece abuts without gap against one of the stops with an abutment surface extending transversely to the displacing direction.
