Abstract
A coupling arrangement for coupling a fuel injector to a fuel rail of a combustion engine, has a fuel injector cup having a central longitudinal axis and is coupled to the fuel rail at a first axial end area of the fuel injector cup, a housing of the fuel injector being arranged at the central longitudinal axis facing a second axial end area of the fuel injector cup, an O-ring seal being arranged between the housing and the fuel injector cup at an axially overlapping area of the fuel injector cup and the housing, a back-up ring being arranged at least partly circumferentially the housing such as to prevent the O-ring seal to be released from the housing, and a separating element being arranged at least partly circumferentially the housing between the O-ring seal and the back-up ring to prevent a contact of the O-ring seal with the back-up ring.
