| description | The invention relates to a fuel injector (1) for injecting fuel into the combustion chamber of an internal combustion engine, said fuel injector (1) comprising a nozzle body (5). A pressure chamber (8) is formed in the nozzle body (5), which is supplied with pressurized fuel via a feed bore (13). A longitudinally movable nozzle needle (7), which opens or closes at least one injection opening (9),is arranged in the pressure chamber (8). A cooling group (100) is arranged so as to at least partially surround the nozzle body (5). The cooling group (100) comprises a cooling ring (101) which delimits a plurality, preferably more than 20, flow channels (200) that can be flown through for cooling the nozzle body (5).
本发明涉及一种用于将燃料喷射到内燃机的燃烧室中的燃料喷射器(1)，其中，所述燃料喷射器(1)包括喷嘴体(5)。在所述喷嘴体(5)中构造有压力室(8)，所述压力室能够经由流入孔(13)供给以处于压力下的燃料。释放或关闭至少一个喷射开口(9)的可纵向运动的喷嘴针(7)布置在所述压力室(8)中。冷却组(100)至少部分包围所述喷嘴体(5)地布置。所述冷却组(100)包括冷却环(101)，所述冷却环限界多个、优选多于20个能被通流的流动通道(200)，用于所述喷嘴体(5)的冷却。 |
