Abstract
A fuel injection assembly for a combustion engine includes an injector body, an injector cupradially enclosing an axial end of the injector body, and a spring clip coupling the injector cup with the injector body. The spring clip includes a ground plate with a main extension plane perpendicular to a longitudinal axis of the fuel injection assembly, a recess extending inwards from a lateral end of the ground plate to a bottom part having a circle-segment contour extending through an angle between 270° to 180°, and at least one spring element fixed to the ground plate. The spring element of the spring clip has a contact region with the injector cup, and the ground plate has a contact region with the injector body, whereby the spring element exerts a spring force on the injector cup. The ground plate of the spring clip extends into a cutout of the injector cup.
