  • Patent number: 12071919
    Abstract: The present invention relates to a nozzle for injecting fuel comprising an orifice in the region of a nozzle tip for leading fuel out of the nozzle and a reception hole for receiving a nozzle needle, wherein the reception hole has a seat region for a sealing closing by a nozzle needle to enable a fuel supply to the orifice in dependence on a position of the nozzle needle, characterized in that the longitudinal axis of the orifice is directed toward a region of the reception hole that adjoins the side of the seat region remote from the nozzle tip.

  • Patent number: 12049860
    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.

  • Patent number: 12025086
    Abstract: The present invention relates to a nozzle of a fuel injector that comprises a pivotably symmetrical nozzle body having a hollow space for introducing a nozzle needle, a nozzle tip that is provided at one longitudinal end of the nozzle body and has openings for discharging fuel, a housing contact surface that is provided at the other longitudinal end of the nozzle body and serves the pressing at a housing of a fuel injector, and an overhang surface that is provided in the longitudinal extent of the nozzle body between the nozzle tip and the housing contact service and that serves the placement of a nozzle clamping nut. The nozzle is characterized in that the minimal distance of the pivot axis of the nozzle body from the overhang surface is smaller than the minimal distance of the pivot axis of the nozzle body from the housing contact surface.

  • Publication number: 20210317807
    Abstract: The invention relates to a method for producing a nozzle, in which an injection orifice of the nozzle for dispensing fuel is produced by means of laser drilling, and a cavity is formed in the nozzle along the longitudinal expansion thereof. The method is characterised in that the cavity formed in the injector is produced after the injection orifice has been produced.
