Abstract: A fuel delivery assembly for an internal combustion engine, including an injector cup, a fuel injector received therein, and a spring clip is disclosed. The injector cup has a circumferential wall with an external shoulder. The fuel injector has a shoulder which is axially spaced apart from the injector cup. The spring clip has a base portion with two radially compliant webs bearing against the shoulder of the circumferential wall and being in force-fit engagement with the circumferential wall. The spring clip has an axially compliant portion bearing against the shoulder of the fuel injector and being elastically deformable to bias the fuel injector in axial direction from the upper end towards the lower end.

Abstract: A fuel rail assembly is disclosed. The fuel rail assembly includes an elongated tubular fuel rail and a plurality of fuel delivery lines for hydraulically coupling the fuel rail to fuel injectors. Each fuel delivery line has an injector cup, a pipe being arranged between the fuel rail and the injector cup, and a fixation bracket. A rigid connection is established between the fixation bracket and a portion of the pipe, the portion being spaced apart from each of the fuel rail and from the injector cup. The injector cup, the pipe, and the fixation bracket are individual parts. The fixation bracket is spaced apart from the injector cup and from the fuel rail.

Abstract: A coupling arrangement (12) includes a housing (6), at least one locking element (14) designed to at least partly surround the housing (6) forming a first area of contact (18) with the housing (6) via a positive locking or frictional connection to limit rotational movement of the housing (6), and a connecting element (16). The connecting element (16), arranged at least partly circumferentially around the housing (6) and being cylindrical with a center axis (X), has at least one locking recess (20) designed to at least partly take in the respective locking element (14) to limit rotational movement of the connecting element (16) via positive locking. The housing (6), the locking element (14) and the connecting element (16) are designed and arranged such as to limit movement of the housing (6) relative to the connecting element (16) at least in one direction of the center axis (X).

Abstract: Coupling device for hydraulically and mechanically coupling a fuel injector to a fuel rail of a combustion engine, the coupling device having a fuel injector cup having a central longitudinal axis and being designed to be hydraulically coupled to the rail and to engage a fuel inlet portion of the injector, a first ring element being fixedly coupled to the cup, a second ring element being fixedly coupled to the injector, and a shell element with a first and second shell part. The first shell part is fixedly coupled to the second shell part. The first and second ring elements are axially arranged between the first and second shell part. The shell element is designed and arranged in a way that the first and second ring element are in engagement with the shell element to retain the injector in the cup in direction of the central longitudinal axis.
