Abstract

Abstract Translated from French L'invention concerne l'alimentation en carburant et en air primaire d'une chambre de combustion notamment pour turbomachines. L'invention a pour objet un dispositif d'injection à bol intermédiaire interposé entre l'injecteur et une coupelle du fond de chambre et comprenant une chambre intermédiaire de refroidissement par impact, le voile aval du bol comportant des orifices de sortie d'air de pulvérisation du carburant régulièrement répartis sur un cercle de diamètre supérieur à celui de la coupelle, ce qui permet d'augmenter le volume réactif de fond de chambre améliorant ainsi le fonctionnement au ralenti et le refroidissement du bol. The invention relates to the supply of fuel and primary air to a combustion chamber, in particular for turbomachinery. The subject of the invention is an injection device with an intermediate bowl interposed between the injector and a cup at the bottom of the chamber and comprising an intermediate chamber for impact cooling, the downstream web of the bowl comprising air outlet orifices for spraying of fuel regularly distributed over a circle with a diameter greater than that of the cup, which makes it possible to increase the reactive volume at the bottom of the chamber, thus improving the idling operation and the cooling of the bowl.
