A fuel injection assembly for an internal combustion engine has a fuel injector, an injector cup and a holding element for securing the fuel injector in the injector cup, wherein the fuel injector has an annular groove defined in part by an annular flange having a profiled peripheral surface engageable by a profiled surface on the arms of a holding element when the fuel injector is secured to the injector cup, to provide a line or point contact between the fuel injector and the holding element.

Fuel injection assembly for an internal combustion engine

The present disclosure relates to fluid injection and the teachings thereof may be embodied in an injector. Some embodiments include an injector comprising: a valve with a valve body and a valve needle; an armature mechanically coupled to the valve needle for moving the valve needle away from a closing position; and a damping element. The valve needle moves in the valve body and seals the valve. The armature displaces the valve needle away from the closing position. The damping element comprises: a hydraulic chamber and a piston arranged to modify a fluid volume of the hydraulic chamber. The piston reduces the fluid volume of the hydraulic chamber when the valve needle moves away from the closing position. A flow restricting orifice hydraulically connects the hydraulic chamber to the cavity.
