Abstract (en)
[origin: DE19541507A1] A fuel injection device for internal combustion engines with high-pressure pump (1), the working chamber (9) of which can be connected on the intake side to a fuel tank (15) via a supply pipe (13) and on the pressure side to a high-pressure manifold (21) via a high-pressure line (19), from which a plurality of injection pipes (23) runs to the individual injection valves (25), and with a pressure valve in the supply pipe (13) and the high-pressure pipe (19), via which the back-flow of fuel from the working chamber (9) into the supply pipe (13) and from the high-pressure pipe (19) into the working chamber (9) is prevented. Here, the pressure valves in the supply pipe (13) and the high-pressure pipe (19) are fitted in a shared compact valve unit (11).
