Abstract
A fuel injector for internal combustion engines. The fuel injector comprises a nozzle needle which is axially displaceably arranged in a nozzle body and is adapted to be lifted off its conical valve seat in response to fuel pressure. A pin of the nozzle needle extends below the valve seat into a cavity provided in the nozzle body. In the nozzle body, below the cavity, there is provided a blind hole having a diameter smaller than that of the cavity. The pin extends into this blind hole when the fuel injector is closed or slightly opened, providing substantial sealing in a radial direction. At least one spray hole enters the blind hole eccentrically in such a way that a clearance is formed which communicates with the cavity.
