Nozzle plate, particularly for fuel injection valves, and method for the production of a nozzle plate

Abstract

A nozzle plate (10), particularly for fuel injection valves, with at least one flow path which has at least one supply opening (12), which path comprises a ring gap (15) which opens into a ring-shaped exit opening (19), as well as a method for the production of such a nozzle plate (10). For the nozzle plate (10), it is provided that the flow path has a ring channel (14) assigned to the supply opening (12), which channel makes a transition into a cylinder-shaped ring gap (15) with a cross-section which narrows in the region of the exit opening (19, 19'). The production of the nozzle plate (10) takes place in that a cavity mold (30) corresponding to the flow path through the nozzle plate (10) is produced, that a layer (44) embedding the cavity mold (30) is galvanically deposited, and that the cavity mold (30) is removed from the galvanically deposited layer (44).
