ABSTRACT:
A fuel injection apparatus for internal combustion engines, which includes a pump piston guided in a cylinder bore driven to reciprocate axially by a cam drive. With a face end, the pump piston defines a pump work chamber, which communicates with an injection valve via a pressure conduit and which is supplied with fuel and relieved via a fuel line. Supply onset and supply end are controllable via a feed pump and a magnet valve are disposed in the fuel line, which communicates with a fuel supply vessel (33) to control supply onset and end of supply. In order to relieve a pressure of the high-pressure chambers, especially at high engine speeds, a fuel tapping device, which is controllable as a function of pressure is connected to a relief line that branches off from the fuel line.
