ABSTRACT:
A pressure regulator including first and second chambers, separated by a diaphragm. By means of a tube centrally penetrating the diaphragm, fuel can be fed under pressure into a first chamber for delivery to an engine. The second chamber communicates with a fuel tank through a spillway and includes therein a compression spring of an overflow valve for diverting fuel from the tube. The overflow valve is embodied as a slide valve and includes a sleeve-like slide that is joined to the diaphragm and has a control opening that cooperates with a control groove of the tube. The pressure regulator for fuel injection systems is intended for disposition in or on a fuel tank so that any returned fuel is led directly into the tank.
