Abstract
A fuel injector assembly has a fuel injector and a coupling device for hydraulically and mechanically coupling a fuel injector to a fuel rail of a combustion engine. The coupling device includes a fuel injector cup configured to be hydraulically coupled to the fuel rail and to engage a fuel inlet portion of the fuel injector, a plate element fixedly coupled to the fuel injector cup and comprising a groove, and a snap ring arranged in the groove and configured to fixedly couple the plate element to the fuel injector to retain the fuel injector in the fuel injector cup in direction of a central longitudinal axis of the fuel injector and to prevent a movement of the fuel injector relative to the plate element in a first direction of the central longitudinal axis. A circlip arranged axially between the fuel injector and the plate element prevents a movement of the fuel injector relative to the plate element in a second, opposite direction of the central longitudinal axis.
