ABSTRACT:
A centrifugal compressor has at least one stage with its own impeller shaft, an inlet and an outlet for gas, and an epicyclic gear train for driving the impeller shaft. The epicyclic gear train comprises three members, a sun gear, a ring gear and a carrier on which a series of planet gears are mounted in mesh with the sun and ring gears. Means is provided for connecting a power input to one of the members of the epicyclic gear train, and means is provided connecting a second of the members to the impeller shaft. Means are provided for controlling the rotational speed of the third of the members to vary the speed of the impeller shaft of the compressor, and actuating means are provided for actuating the control means in response to the pressure of the compressed gas at the outlet.
