Abstract (en)
The present invention relates to a fluid injection assembly (1), comprising an injector (2), a fuel cup (3) and a spring (4), wherein the spring (4) is arranged between a supporting surface (5) of the injector (2) and a supporting surface (6) of the fuel cup (3). In order to improve such a fluid injection assembly, the invention suggests that the spring (4) extends along a longitudinal axis (7) of the spring (4) and that the spring (4) comprises a wire (8) wound around the longitudinal axis (7) of the spring (4) between a first longitudinal end (9) of the spring (4) and a second longitudinal end (10) of the spring (4). According to a second aspect the invention refers to a combination, in particular for a fluid injection assembly (1) of an internal combustion engine, wherein the combination (35) includes a spring (4) and a fixing element (24). In order to provide an improved combination (35) the invention suggests that the spring (4) extends along a longitudinal axis (7) of the spring, wherein the spring (4) comprises a wire (8) wound around the longitudinal axis (7) of the spring (4) between a first longitudinal end (9) of the spring (4) and a second longitudinal end (10) of the spring (4), and that the fixing element (24) has a ring section (25) and a sleeve section (26) extending along a longitudinal axis (27) of the fixing element (24), wherein the ring section (25) is formed at or fixed to the sleeve section (26) between a first longitudinal section (28) of the sleeve section and a second longitudinal section (29) of the sleeve section (26) and wherein the ring section (25) extends from an outside of the sleeve section (26) in a radially outward direction.
