Abstract
An electromagnetic valve consists of two valve housing parts, connected by crimping and axially braced, and having a magnetic pipe care therein. A flat armature is positively connected with a spherically shaped valve closing part, which extends through a central opening in a guide membrane for cooperation with a valve seat. The guide membrane rests via an outer circumference on a collar and is supported there via the axial tensioning force between the valve housing parts in assembled form. The guide membrane is welded to the collar on the outer circumference upon at least two points. Before the valve housing parts are combined, the guide membrane, abutting the collar, in concentrically guided into position by a centering body, having a slightly larger diameter than the valve closing part, on the valve seat and is welded at said points in this position. Thereupon the centering body is removed and the actual assembly of the valve is performed.
