CA 2549136

A compressor comprises a rotor (13) which has several rotor blades (14, 14') which are arranged successively at a distance from each other in an axial direction. A plurality of heat-accumulating segments (10), which are detachably fixed to the rotor (13) in a successive manner in the direction of the periphery and which can be displaceably mounted in the direction of the periphery, are arranged between adjacent rows of rotor blades (14, 14') on the periphery of the rotor (13). Security means (15) are provided on the heat- accumulating segments (10). Said security means are used to secure the heat- exchanging segments against displacement in the direction of the periphery. Production and mounting of the inventive rotor are simplified by virtue of the fact that only one part of the heat-accumulating segments (10) is provided with said security means (15).

L'invention concerne un compresseur comportant un rotor (13) présentant axialement plusieurs rangées d'aubes mobiles (14, 14') espacées les unes derrières les autres, plusieurs segments d'accumulation thermique (10), fixés de façon amovible au rotor (13), étant disposés les uns derrière les autres entre des rangées adjacentes d'aubes mobiles (14, 14') sur la périphérie du rotor (13), dans le sens périphérique, de manière à coulisser dans le sens périphérique. Lesdits segments d'accumulation thermique (10) comportent des éléments de fixation (15) fixant les segments d'accumulation thermique (10) contre le déplacement dans le sens périphérique. Dans le cas d'un tel rotor (13), la fabrication et le montage sont simplifiés du fait qu'une partie seulement des segments d'accumulation thermique (10) est pourvue d'éléments de fixation (15).
