摘要： The invention relates to a nozzle assembly (1) for a fluid injector. The nozzle assembly (1) comprises a nozzle body (2) with a central axis (Z), the nozzle body (2) having a nozzle body recess (21), at least one injection opening (22) and an outer wall (24) facing away from the nozzle body recess. The nozzle assembly (1) further comprises a nozzle tension nut (3) by means of which the nozzle body (2) can be coupled to an injector body (4), the nozzle tension nut (3) having an inner wall (31) facing the outer wall (24) of the nozzle body (2). The nozzle body (2) and the nozzle tension nut (3) are formed such that, under the effect of an operational pressure exerted in ordinary operation by a metered fluid onto the nozzle body recess (21), the outer wall (24) of the nozzle body (2) rests, at least in part, against the inner wall (31) of the nozzle tension nut (3) in the radial direction (200). The invention further relates to a fluid injector with a nozzle assembly (1) and an injector body (4).

摘要： The invention relates to a method for producing a nozzle body, wherein an unfinished nozzle body (1) is provided, which has a center axis (3) and which has a first and a second axial end with respect to the center axis (3). Proceeding from the first axial end, an unfinished cavity (5) is created in the unfinished nozzle body (1), and thereby an unfinished wall (7) is formed between the unfinished cavity (5) and an outer region of the unfinished nozzle body (1). By means of an electrochemical processing operation, which comprises electrochemical removal, at least part of a contour of the unfinished wall (7) is modified and thus a wall of a cavity of the nozzle body is produced.

摘要： The invention relates to a fuel injection valve for directly injecting fuel, gasoline or diesel, at a targeted time and quantity, into the combustion chamber of a cylinder of a running internal combustion engine. The fuel injection valve comprises an injector body (1) having a receiving hole (3) for an injector needle (6), the receiving hole (3) being implemented as a blind hole. The receiving hole forms an injector ring chamber (3a) in the injector shaft (2) and forms a cone-shaped valve seat (4) at the base thereof, and a blind injector hole (8) in the region of the tip of the cone of the valve seat, from which extends at least one injector hole (5). The injector needle (6) disposed displaceably in the longitudinal direction in the receiving hole (3) comprises an at least partially cone-shaped needle tip (7) and seals off the blind injector hole (8), and thus the at least one injector hole (5), from the injector ring chamber (3a). The needle tip (7) of the injector needle (6) is characterized in that said tip comprises a needle pilot (9) adapted in contour and extent to the blind injector hole (8) in the valve seat (4), said pilot protruding into the blind injector hole (8) and thus reducing a compression volume (10) formed between the valve seat (4) and injector hole (5).
