Abstract

A compressor unit intended for delivering a pressurised gaseous medium at a varying outlet flow volume to a consumer with varying load demands and comprises one or more rotors (K; 10, 11 ) forming one or more compressor stages and arranged to operate continuously at high speed thereby delivering a certain outlet flow volume, a drive motor (M; 19 ), a drive line assembly (N; 17, 18 ) mechanically coupling the compressor rotor or rotors (K; 10, 11 ) to the drive motor (M; 19 ), and a waste flow circuit connected to the outlet end of the compressor stages and incorporating at least one power recovery turbine (T<SUB>R</SUB> ; 22, 23 ) mechanically coupled to the drive line assembly (N; 17, 18 ), and one or more valves (V; 25, 34, 35 ) controlling the waste flow through the waste flow circuit in response to the actual load demand, wherein the power recovery turbine or turbines (T<SUB>R</SUB> ; 22, 23 ) are arranged to deliver power back to the drive line or drive lines (N; 17, 18 ) at consumer load demands smaller than the certain outlet flow volume delivered by the compressor rotor or rotors (K; 10, 11 ).
