Abstract
A fuel injection system for an internal combustion engine contains a fuel metering mechanism including first differential pressure diaphragm valves. The pressure difference prevailing at these valves can be changed by a second, electromagnetic, differential pressure diaphragm valve. The first and second differential pressure valves share a common diaphragm and the pretension of the closing spring in the second diaphragm valve can be adjusted from outside the housing of the fuel metering mechanism.
