Abstract

a. L'invention concerne une buse d'injection de carburant comprenant une aiguille de soupape munie d'un cône d'étanchéité commandant les orifices d'injection, le corps de buse présentant une chambre de pression et un logement à fond plein. b. Cette buse est caractérisée en ce que les orifices d'injection sont rendus étanches aussi par rapport au logement à fond plein par le cône d'étanchéite, un canal de décharge étant disposé dans l'aiguille de soupape pour relier le logement à fond plein et la chambre de pression. c. L'invention est applicable aux moteurs à combustion interne à injection.at. The invention relates to a fuel injection nozzle comprising a valve needle with a sealing cone controlling the injection ports, the nozzle body having a pressure chamber and a solid-bottom housing. b. This nozzle is characterized in that the injection orifices are also sealed with respect to the solid-bottom housing by the sealing cone, a discharge channel being arranged in the valve needle to connect the solid-bottom housing and the pressure chamber. vs. The invention is applicable to internal combustion injection engines.
