Abstract
A nozzle body for a fluid injection includes a cavity and a bottom wall delimiting the cavity at a fluid outlet end. The bottom wall is perforated by an injection hole having an inlet opening at an inner surface of the bottom wall and an outlet opening at an outer surface of the bottom wall. The outlet opening has an elongated slit shape having a centerline which is a circular arc with respect to the longitudinal axis. The inlet opening is spaced apart from the longitudinal axis by a radial distance. The inner surface has a concave shape extending away from the fluid outlet end from an apex of the inner surface. Further, the inlet opening is spaced apart from the apex by an axial distance that is smaller than said radial distance.
