Patent ID: 6890151

Claim:
Fixed sectorized guide vane assembly for a compressor of a turbomachine, comprising: sectors in the shape of an arc of a circle each composed of an inner segment and an outer segment connected by vanes, a circular casing integrated into the compressor stator, that will support the sectors in contact with each other, anti-rotation means designed to prevent sectors supported by the casing from rotating, wherein: the casing is composed of at least two parts, in contact with each other and fixed to each other at joint planes and including means forming a slide, the sectors form slider means adapted to the means forming a slide in the parts of the casing, and anti-rotation means comprise anti-rotation means fixed to the joint planes of the parts of the casing by attachment means, and anti-rotation means blocked on the parts of the casing by locking means at the contact between sectors, the casing comprises two radial sides facing each other, the means forming a slide comprise two grooves opposite each other formed in the sides, the edges of the outer segments of the sectors forming the slider, the anti-rotation means fixed to the joint planes comprise at least one strip immobilized between the two grooves by said attachment means and forming a stop for the sector sliding in the slide in the casing, and the strip is a two-arm clip inserted by bringing two arms towards each other in reception housings provided in the grooves, and immobilized in these housings when the two arms are released, thus forming said attachment means.
