Distributor sectors (25) on which fixed vanes are placed adjacent to a casing (31) by means of sealing sectors (32) alternating with them in the axial direction and provided with force resistant faces (37; 39) through which forces exerted on the distributor sectors are transmitted to the casing. The inner surface of the casing (31) is smoother and is not fitted with any hooks; consequently, this casing (31) is less complicated to make and is less mechanically stressed to retain the distributor sectors, and the distributor sectors may be installed by a purely axial movement.
Secteurs de distribution (25) sur lesquels des volets fixes sont placés de manière adjacente à un caisson (31) au moyen de secteurs de scellement (32), en les alternant dans la direction axiale et dotés de faces résistantes à la force (37; 39) par lesquelles les forces exercées sur les secteurs de distribution sont transmises au caisson. La surface interne du caisson (31) est plus lisse et ne comporte pas de crochets. Par conséquent, ce caisson (31) est moins compliqué à réaliser et est moins soumis aux contraintes mécaniques pour conserver les secteurs de distribution, et ces derniers peuvent être installés par un mouvement purement axial.
