ABSTRACT:
A pressure control valve suitable for liquid or gaseous media with a short force conduction path is to be created, permiting the use of plastic as a material for the housing. The pressure control valve has a chamber carrying the medium, which is formed by a housing element and a diaphragm. A seat valve located in the chamber has a valve closing element secured to the diaphragm. A prestressed spring disposed in the chamber at least indirectly engages the housing part on one side and the valve closing element on the other. The spring acting as a tension spring is in the form of an annular washer and occupies little space. The pressure control valve is intended for liquid or gaseous media, and in particular for use in fuel injection systems of internal combustion engines.
