Abstract
A process to supercharge and control a compressor comprising a single screw co-operating with at least two pinions in order to constitute as many partial compressors as there are pinions, such partial compressors operating in parallel and one of them at least being provided with a delivery control device, wherein the supercharging flow is injected into only one of the partial compressors and the delivery of the compressor is controlled from maximal delivery by reducing at first the deliveries of those partial compressors into which the supercharging flow is not injected.
