Fuel injector

The injector has a valve member, which can be moved in axial direction against a cylindrical spring bush (1; 1') for supplying fuel to the combustion chamber. The spring bush has several radial levels with two recesses (5, 5a, 6). The spring bush is formed and rolled into a plate into the case. Two edges of the plate are separated from each other, such that in one radial level the two edge recesses are closed to the edge of the plate (3) and that the edge differentiates from the edge-far recesses. The two edge recesses alternate in the radial levels to the edge and are closed or open. The recesses have an identical form.
