A multistage turbocompressor, designed as a geared compressor with an integrated gear, contains a central greater wheel ( 9 ) that meshes with a plurality of pinions ( 14, 15 ), wherein each pinion ( 14, 15 ) is mounted, in a manner adapted to rotate in unison, on a pinion shaft ( 16, 17 ). A bladed wheel of a compressor stage (II, III, IV, V) is arranged on the ends of each of the pinion shafts. The greater wheel ( 9 ) meshes with a driving pinion ( 8 ), which is mounted, in a manner adapted to rotate in unison, on a driving shaft 6 connected to a drive unit ( 1 ). The axis of the driving pinion ( 8 ) is arranged, with the axis of the greater wheel ( 9 ), in the same horizontal plane ( 20 ), and the driving pinion ( 8 ) meshes with a pinion ( 10 ) of a first compressor stage (I) mounted, in a manner adapted to rotate in unison, on a pinion shaft (11).
