Abstract:
A coupling device for hydraulically and mechanically coupling an injection valve to a fuel rail of a combustion engine, has a fuel injector cup with a central longitudinal axis which can be hydraulically coupled to the fuel rail and at least partially engaged with the fuel inlet tube. The cup has an inner bottom surface facing the valve, a first retaining element fixedly coupled to the cup, a second retaining element fixedly coupled to the valve, wherein the second retaining element is coupled to the first element to prevent a movement of the second element relative to the first element in a first axis direction, and a damper element which is arranged axially between the inner bottom surface of the cup and the inlet tube. The damper element limits a movement of the valve relative to the cup in a second direction of the longitudinal axis opposing the first direction.
