Fuel injection valve with a nozzle disk and method for the production of the nozzle disk with an asymmetrical mandrel

摘要

Fuel injection valve (100) for metering, atomizing and targeted injection of fuel, wherein the fuel injector includes:a seat (138), which has a passage (138b), which extends along a longitudinal axis;a movable element (122) with said seat (138), so that a flow of fuel through the passage (138b) and to make it possible to prevent anda medication dispensing - nozzle disk (140), which comprises:an element which a first and a second surface (20, 40; 22, 42), which in the whole are parallel, wherein the first surface (20; 22) on the whole with respect to the seat (138) is arranged and the second surface (40; 42) on the opposite side as the first surface (20; 22); andan opening (32), which extends through the element and is defined by a wall, which the first and second surface (20, 40; 22, 42), said wall:a first section (32c, 32d), which in a distance from the first surface (20) is arranged, wherein the first section (32c, 32d) of the wall in the substantially perpendicular to the first and second surface (20, 40; 22, 42), the on the whole are planar; anda second portion (32a; 32b), of the first section (32c, 32d) with the first surface (20), the second section (32a; 32b) of the wall at a first inclined angle with respect to the first surface (20), and the first inclined angle with respect to the longitudinal axis (200) being varied, the dosing - nozzle disk (140) further comprises: ..
