Abstract

A centrifugal supercharger has an impeller (211) having blades (216) so arranged that the flow path through the impeller increases in cross-sectional area radially outwards. A moveable shroud (220) can be lifted to increase the clearance of the shroud from the impeller to counteract surge. A moveable plug may be withdrawn from the volute of the supercharger to allow air to circulate repeatedly in the volute to further unload the impeller.
