Abstract
A nozzle for a fuel injector the nozzle having a pivotably symmetrical nozzle member with a hollow space for introducing a nozzle needle, a nozzle tip at a longitudinal end of the nozzle member, at least one opening channel extending in a straight line for the discharge of fuel, and a nozzle needle arranged in the hollow space for selectively blocking an fuel inflow to the at least one opening channel. The nozzle is characterized in that the at least one opening channel has a center axis that is skewed with respect to the longitudinal axis of the nozzle member.
Claims16
A nozzle for a fuel injector comprising:
- a pivotably symmetrical nozzle member having a hollow space for introducing a nozzle needle;
- a nozzle tip at a longitudinal end of the nozzle member, wherein the nozzle member has a plurality of opening channels extending in a straight line for discharging fuel;
- and
- a nozzle needle arranged in the hollow space, wherein the nozzle needle is configured to selectively block a fuel supply to the plurality of opening channels,
- wherein
- each of the plurality of opening channels has a center axis that is skewed with respect to a longitudinal axis of the nozzle member and defines a one sheet hyperboloid.
