摘要

The invention relates to a nozzle body having a nozzle needle cut-out that is arranged about a longitudinal axis, comprising a conical nozzle needle seat which leads into a blind hole, and at least one injection hole, which extends from the blind hole to an outer surface of the nozzle body. At the transition to the conical nozzle needle seat, the blind hole has a blind hole diameter and extends from the transition in the axial direction all the way to a blind hole depth, wherein the ratio of the blind hole diameter to the blind hole depth is greater than or equal to 1.5. The invention further relates to an assembly consisting of a nozzle body and a nozzle needle and to a fuel injector.
