  • Patent number: 10047711
    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.

  • Patent number: 9593654
    Abstract: An injector sleeve adapted to be mounted in a cylinder head of an internal combustion engine, where the injector sleeve comprises a tapered inner surface which constitutes a sealing surface for an injector, where the hardness of the tapered inner surface is higher than the hardness of the outer surface of the injector sleeve. The injector sleeve is produced in a cold forming process. The advantage of the invention is that the injector sleeve is provided with a sealing surface for an injector which is harder than the outer surface of the injector sleeve. In this way, a sealing surface for an injector having small tolerances is obtained without further machining, where the outer surface may be turned to the desired dimensions.
