Abstract (en)

A nozzle body (1) for a fluid injector (30) comprises a nozzle wall (3) which limits an opening (5) of the nozzle body (1) along a longitudinal axis (L) from a fluid inlet end (21) to a fluid outlet end (22). The nozzle body (1) further comprises a needle seat (7) formed as a portion of the nozzle wall (3) to interact with a needle (32) to prevent a fluid flow through a flow hole (13) in a closed position and otherwise to enable it. The flow hole (13) penetrates the nozzle wall (3) in the region of the fluid outlet end (22) from the opening (5) to outside of the nozzle body (1). The nozzle body (1) further comprises a sac volume portion (9) of the nozzle wall (3) formed in the region of the fluid outlet end (22) such as to limit a sac volume (11) wherein the sac volume portion (9) comprises a protrusion (10) inside the sac volume (11) formed in one piece with the nozzle wall (3) extending along the longitudinal axis (L).
