Abstract

Known pressure regulator valves for motor vehicles are comprised of a relatively large number of individual parts that have to be assembled at a high cost. In the pressure regulator valve set forth, the stop piece and the housing part are injection molded. This reduces assembly costs in the manufacture of the pressure regulator valve. The pressure regulator valve is particularly suited for fuel delivery systems of motor vehicles with an internal combustion engine.
