A method of producing an electromagnetic valve includes deep drawing of a magnet housing, arranging a magnet coil, a magnet core and a plunger connected with an armature in the magnet housing, connecting a valve closing element which has a valve element for controlling a pressure medium flow, with the magnet housing by flanging a flared flange with a shoulder of the magnet housing relative to the valve closing element, and producing both the flared flange and the shoulder during the deep drawing of the magnet housing in a non-material-removing deformation step.

Method of producing electromagnetic valve

An electromagnetically operated proportional valve, in particular a pressure regulating valve for automatic transmission of motor vehicles has a magnet housing, a magnet coil and stationary flux guiding elements received in the magnet housing, a magnet armature, a valve member with which the magnet armature cooperates, stationary structural elements forming at least one auxiliary air gap and a working air gap in a magnetic circuit, the valve member cooperating with the stationary structural elements through the at least one auxiliary air gap and the at least one working air gap, at least one of the structural elements cooperating in the working air gap being at least partially provided on at least one surface facing a corresponding another structural element with at least one nonmagnetic coating.

Electromagnetically operated proportional valve

An electromagnetic valve, in particular switching or pressure regulating valve for an automatic transmission of motor vehicles has a magnet housing, a magnet coil with a coil body received in the magnet housing, a valve member, a magnet armature through which the magnet coil cooperates with the valve member, a valve closing part connected with the magnet housing, electrical contacts for controlling the magnet coils and arranged outside of the magnet housing, and conductors extending through the magnet housing and connecting the electrical contacts with the magnet coil. The magnet housing is composed of at least two magnet casing elements, including a first magnet casing element and also a second magnet casing element which at least partially overlaps the first magnet casing element, at least one of the magnet casing elements having a recess through which the conductors extend to the electrical contacts.
