Abstract:
A fuel system serves to supply fuel to an internal combustion engine includes a reservoir and a first fuel pump whose input is connected to the reservoir and a second fuel pump whose input is connected to the first fuel pump. At least one injection valve is connected to the second fuel pump and can supply fuel at least indirectly to a combustion chamber. A leakage line is provided between the second fuel pump and the reservoir. In order to permit a reliable hot start of the engine with a simultaneously low strain on the components, the leakage line is provided with a valve device which has a shutoff function and a pressure relief function that are connected in parallel with each other.
