Abstract

A pressure regulator for regulating fuel pressure in an internal combustion engine, containing a valve including a closing member forced into a valve seat by the action of an angularly shaped valve leaf spring one arm of which is braced on the closing member and the other arm is braced on a support member of a regulator housing. In the region of its angled portion, the leaf spring is fixed on a pin supported in the regulator housing, and the bearing of the pin in the regulator housing contains side walls of the regulator housing that wrap around bearing bores in the valve leaf spring with parallel spacing and that extend substantially perpendicular to the pin. The side walls are overlapped at least in part by tabs that are connected to the support member of the regulator housing and are provided with bearing bores for the pin which are coaxial relative to the bearing bores in the side walls.
