A process for the preparation of a pressure regulating valve for an automatic transmission of a motor vehicle and the pressure control valve

摘要

The method includes the steps of joining a magnet part (11) comprising a coil (20) and a magnetic armature (26), and a valve connection element (40) comprising a valve slide (55) and connections (T,P,A), so that the magnetic armature engages with the valve slide, and that a rising or falling pressure can be produced at a load, with increasing current flow through the coil. The magnet part can be combined with different valve connection elements, whereby a desired course of the pressure at the load at increasing current flow through the coil is achieved through the arrangement of the connections in the valve connection element, and the design of the valve slide. An Independent claim is provided for a pressure control valve manufactured according to the method.
