Abstract:
A fuel supply system for furnishing fuel for an internal combustion engine, comprising a fuel tank, a first fuel pump (6), a second fuel pump (12), at least one fuel injection valve, wherein the first fuel pump (6) pumps the fuel from the fuel tank into a fuel connection and the second fuel pump (12) pumps the fuel from the fuel connection via a pressure line to the fuel injection valve, by way of which the fuel can at least indirectly reach a combustion chamber of the engine, a relief device (33, 33a, 33b, 33') is provided, by which the pressure of the fuel in the pressure line (14) is lowered as a function of at least one engine operating condition, a valve device (30, 30d) is provided that varies a feed pressure in the fuel connection (10) which varies the feed pressure as a function of the engine operating condition, and the valve device (30, 30d) has a flow resistance that is dependent on the flow of fuel flowing through the valve device (30, 30d).
