Coupling arrangement

摘要

Coupling arrangement (22) for coupling a fuel injector (20) to a fuel rail (18), the coupling arrangement (22) comprising a fuel injector cup (24) being designed to be coupled to the fuel rail (18) and to a ring element (36) by a circlip (38), wherein the fuel injector cup (24) comprises at least two slots (66) and at least two grooves (68) being arranged at least partly circumferentially the fuel injector cup (24) and axially overlapping with the slots (66). Furthermore, the coupling arrangement (22) comprises the ring element (36) facing the fuel injector cup (24) and being coupled to a housing (44) of the fuel injector (20), wherein the ring element (36) comprises at least two protrusions (58) facing the fuel injector cup (24) and the protrusions (58) comprise at least two grooves (60) being arranged at least partly circumferentially the ring element (36) in a common plane with the grooves (68) of the fuel injector cup (24). The circlip (38) is arranged at least partly circumferentially the fuel injector cup (24) at least partly in the grooves (68) of the fuel injector cup (24) and is arranged at least partly circumferentially the ring element (36) at least partly in the grooves (60) of the ring element (36).
