Abstract

A pressure regulating device is proposed which regulates the fuel pressure in a fuel injection system for internal combustion engines. The pressure regulating device includes a pressure regulating valve which has a valve diaphragm fastened in a valve housing and arranged to define a fuel chamber which communicates via inlet pipes with a fuel distributor line. Protruding into the fuel chamber is a valve seat body joined to the valve housing, on one end of which body a valve seat is formed and the other end of which engages an outlet conduit which protrudes through the wall of the fuel distributor line remote from the pressure regulating valve and is tightly joined to this wall.
