Abstract
A pressure regulating device is proposed, which serves to regulate 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 defining a fuel chamber which communicates via an inflow opening 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 is embodied as an outlet pipe that passes through the wall of the fuel distributor line. The fuel distributor line is formed of two shell halves inserted one inside the other, of which the first shell half has a tub-shaped end into which the pressure regulating valve is inserted and with which it is securely fastened.
