Abstract

Soupape à corps pénétrant dans la chambre de combustion du cylindre, logeant un pointeau qui coopère avec un siège et comportant à l'extrémité tournée vers la chambre de combustion deux rangées superposées, concentriques d'orifices calibrés répartis à la circonference et par lesquels le carburant passe périodiquement du siège dans la chambre de combustion en soulevant le pointeau. Les rangées d'orifices calibrés 8 et 9 sont disposées dans le corps 3 de manière à être séparées sur le circuit du carburant sous toutes les charges du moteur et un pointeau individuel 17 et 22 commande l'arrivée du carburant à chaque rangée d'orifices. Application aux moteurs subissant des variations de charge afin de permettre l'injection du carburant à des débits différents aux régimes en pleine charge et à charge partielle.Body valve penetrating into the combustion chamber of the cylinder, accommodating a needle which cooperates with a seat and comprising at the end facing the combustion chamber two superimposed rows, concentric with calibrated orifices distributed around the circumference and through which the fuel periodically passes from the seat into the combustion chamber by lifting the needle. The rows of calibrated orifices 8 and 9 are arranged in the body 3 so as to be separated on the fuel circuit under all engine loads and an individual needle 17 and 22 controls the arrival of fuel at each row of orifices . Application to engines undergoing load variations in order to allow fuel injection at different flow rates at full load and partial load speeds.
