Abstract (en)
[origin: WO2015090961A1] The invention proposes a fuel supply device of a fuel injection system of an internal combustion engine, and an embodiment of the overflow valve (30) for the same. The fuel supply device has a high-pressure pump (18) in addition to the overflow valve (30). The overflow valve (30) conducts a nonrequired fuel quantity from the high-pressure pump (18) into a spill line (28). The overflow valve (30) has a spring chamber (32) which is hydraulically connected to the spill line (28). For the hydraulic connection of the spring chamber (32) to the spill line (28), a discharge line (29) is provided which is hydraulically connected to a suction side (41) of a Venturi nozzle (40).
