Abstract
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.

Arrangement for attachment of vane support distributor sectors (25) to a stator casing (31) around an arc of a circle, including bearing faces (29, 30, 37, 38, 39) in the radial and axial directions for the sectors, distributed on the casing, and independent attachment parts, including at least one face facing radially outwards (37) and one face facing the radial direction (39) both of which resist forces applied on the vanes in the sectors, sealing sectors (32) being fixed to the casing and alternating with the distributor sectors in the axial direction, characterized in that the said force resistance faces facing the radially outwards direction and the axial direction are located on the sealing sectors.
