Fuel supply device of a fuel injection system of an internal combustion engine, and overflow valve for the same

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). 本发明涉及种内燃机燃料喷射系统的燃料供应装置以及种用于此的溢流阀(30)。该燃料供应装置除了所述溢流阀(30)外还具有高压泵(18)。溢流阀(30)将高压泵(18)不需要的燃料导出到泄放管道(28)中。溢流阀(30)具有弹簧室(32)，该弹簧室和泄放管道(28)液压连接。为了使弹簧室(32)与泄放管道(28)液压连接，设置有排出管道(29)，该排出管道液压连接到文杜里喷嘴(40)的吸入侧(41)上。
