ABSTRACT:
A regenerative turbomachine, especially a compressor, in which the working fluid entering via an inlet (16) is divided into slip and counter flow stream. In the each direction, guide means define successive passes through the rotor blades (13) in a generally axial sense. In the slip direction, successive passes (1.sub.DS, 2.sub.DS, 3.sub.DS, etc) are made so as to reintroduce the fluid to the rotor blades at circumferential positions spaces successively in the direction of intended rotor rotation. In the counter flow path successive passes (1.sub.DC, 2.sub.DC, 3.sub.DC, etc) are made so as to reintroduce the fluid at circumferential positions spaced successively in the direction counter to the intended direction of rotor rotation. The slip and counter flow paths are brought together at a common outlet (21), thus obviating the need for a conventional stripper. Intercooling (24) may be provided in at least some passes.
