A fuel injection system which serves to supply fuel to an internal combustion engine. The fuel injection system includes a metering and quantity distribution valve with regulating valves connected at the output side, which valves can be influenced by the fuel pressure in a differential pressure control line. Communicating with a fuel supply line is a fuel reservoir, which has a flexible diaphragm which is displaceable by the fuel pressure counter to a reservoir spring in a spring chamber. Shortly before the end of the movement of the flexible diaphragm into the spring chamber, a spring plate resting on the flexible diaphragm opens a sealing valve via a stem. The sealing valve rests on the mouth of an outflow line, which leads via a control throttle to the differential pressure control line. A pressure maintenance valve is likewise disposed upstream of the sealing valve, and a line from a pressure limitation valve and a leakage line from the metering and quantity distribution valve discharge between the pressure maintenance valve and the sealing valve. The spring chamber of the fuel reservoir communicates via a return flow line with the fuel container.
