A centrifugal pump-compressor includes a chamber adapted to rotate about a predetermined axis and vanes extending radially with respect to such axis and adapted to impel a fluid at least in the radial direction of the chamber. The vanes induce a primary flow of the fluid in the chamber. The apparatus further includes a series of venturis disposed in the chamber and adapted to receive the primary flow therethrough. The outwardly disposed venturis generally overlap the immediate adjacent inwardly disposed ones. A diffusing sink is positioned between the venturis. The primary flow of fluid is accelerated as it passes through each of the venturis, its velocity then decreases and the pressure in the fluid increases in each of the diffusing sinks. In this manner the energy of the fluid is converted successively from kinetic to potential forms as it moves outwardly through the chamber. Additional vanes are disposed within the chamber to increase the circumferential velocity of the fluid as it enters the several diffusing sinks.
