Nozzle Head and Fluid Injection Valve

摘要

The invention relates to a nozzle head and to a fluid injection valve, in particular to a motor vehicle injection valve. A nozzle head for atomizing a fluid for a fluid injection valve with a valve body, through which flow can pass, may include a longitudinal axis and a nozzle perforated disk having a front surface and an opposite inner surface. The nozzle perforated disk may comprise at least one nozzle hole channel completely penetrating the nozzle perforated disk in the direction of the longitudinal axis and including includes an entry surface at a first channel end and an outlet surface at a second channel end wherein the entry surface is formed on the inner surface of the nozzle perforated disk. A nozzle hole projection of the nozzle hole channel has a channel wall with a wall height (h) extending away from the inner surface and is configured over a circumference of the nozzle hole projection so that the second channel end corresponds to a channel wall end of the channel wall configured so as to face away from the front surface.
