Abstract

L'invention concerne un module (1) de chambre de combustion pour une turbomachine, comportant une chambre de combustion (2), une bougie d'allumage (9) montée dans un orifice (11) de la chambre de combustion (2), des moyens (7, 8) d'amenée d'air et de carburant dans la chambre de combustion (2), caractérisé en ce qu'il comporte un organe (16) mobile entre une position escamotée dans laquelle il est dégagé de la chambre de combustion (2) et une position déployée dans laquelle ledit organe (16) s'étend dans la chambre de combustion (2) de manière à former un obstacle situé dans le flux d'air et de carburant au sein de la chambre de combustion (2).The invention relates to a combustion chamber module (1) for a turbomachine, comprising a combustion chamber (2), a spark plug (9) mounted in an orifice (11) of the combustion chamber (2), means (7, 8) for supplying air and fuel into the combustion chamber (2), characterized in that it comprises a member (16) movable between a retracted position in which it is released from the chamber combustion chamber (2) and an extended position in which said member (16) extends into the combustion chamber (2) so as to form an obstacle in the flow of air and fuel within the combustion chamber (2).
