Abstract

Soupape comprenant un corps pénétrant dans la chambre de combustion du cylindre, logeant un pointeau qui coopère avec un siège et comportant plusieurs orifices calibrés qui sont répartis à sa circonférence et par lesquels passe périodiquement le carburant en soulevant le pointeau pour parvenir du siège dans la chambre de combustion. La soupape comporte un dispositif tel qu'un manchon 16 qui est indépendant du pointeau et qui libère une partie de la section de tous les orifices calibrés 7 lorsque le moteur est en régime à charge partielle, mais qui libère la section totale de tous ces orifices lorsque le moteur est en régime à pleine charge. Application aux moteurs à injection et dont le régime est susceptible de varier, afin que les jets de carburant et donc la combustion demeurent également bons à toutes les charges.Valve comprising a body penetrating into the combustion chamber of the cylinder, housing a needle which cooperates with a seat and comprising several calibrated orifices which are distributed around its circumference and through which the fuel periodically passes by lifting the needle to arrive from the seat into the chamber combustion. The valve comprises a device such as a sleeve 16 which is independent of the needle and which releases a part of the section of all the calibrated orifices 7 when the engine is in mode at part load, but which releases the total section of all these orifices. when the engine is running at full load. Application to injection engines, the speed of which is liable to vary, so that the fuel jets and therefore combustion also remain good at all loads.
