Abstract:
1. A hinged armature valve comprising a drive part having a drive part housing in which an electromagnet unit with an iron core and a coil is arranged, a control part secured on the drive part, said control part having a control part housing, in which a control chamber is formed covered over by the drive part on it, in which control chamber a hinged armature is located, which in alternate succession can open and close a first valve opening formed on the drive part and surrounded by a first valve seat and a second valve opening formed in the control part housing and surrounded by a second valve seat, and a receiving recess, surrounding the first valve opening, in the drive part, such recess containing a return spring biasing the hinged armature into a home position closing the second valve opening, wherein the electromagnet unit is completely received in the drive part housing, the drive part housing being in the form of a plastic part molded by injection molding on the electromagnet unit; the receiving recess and the first valve seat are direct components of the drive part housing and are produced during injection molding of the drive part housing; the component part housing, also designed as a plastic part, defines the control chamber together with the drive part and is so formed at the control chamber that it sets the position of the hinged armature in its longitudinal and transverse direction; and the two housings directly engage each other and in the joint region are connected together by a surrounding laser weld seam in a gas-tight fashion.
