ABSTRACT:
A pressure control valve for an automatic transmission of a motor vehicle includes a valve unit (10) extruded from plastic, which is disposed coaxially to an actuator unit and serves for control of a fluid flow between a supply port (18) and a consumer port (16) and in which fluid channels (24, 26) and a valve chamber (30) are formed, in which a valve closing member is arranged. The fluid channels (24, 26) and the valve chamber (30) are formed on an injection-molded preform (22), which is injected into a flange (12).
