ABSTRACT:
A fuel quantity distributor in which a continuously operating suction pipe injection device is provided with differential pressure valves corresponding to the number of cylinders arranged about the metering unit. The valves maintain the pressure difference of the fuel constant by the metering unit. The valves have, furthermore, a diaphragm which contacts on one side, the delivered fuel. The other side of the diaphragm is exposed to a control pressure. Each of the differential pressure valves is equipped with one of these diaphragms in the form of a metal diaphragm in the plane of the vave seat. A centering ring with a crushing edge for a seal ring, is located in the distributor housing. The metal diaphragm is fixed relative to the valve seat by this centering ring through the use of a cup spring. The diaphragm, moreover, is located in a carrier within the distributor housing. The carrier has a two-part capsule with one half having a diaphragm support ring with inside diameter larger than that of the associated shell of the pressed-on second half of the capsule.
