Abstract (en)
[origin: WO2007122023A1] A high-pressure fuel delivery device (18) for an internal combustion engine comprises a high-pressure pump (36) and a low-pressure flow path (72). Said low-pressure flow path (72) leads from a fuel inlet (28) of the high-pressure fuel delivery device (18) to a holding space (40) for a driveshaft (44) of the high-pressure pump (36) and onward to at least one inlet valve (56) of the high-pressure pump (36). Leakage and/or lubricating fuel is recirculated via a recirculation flow path (62). It is proposed that the recirculation flow path (62) opens out (66) into the low-pressure flow path (72).
