Jy/5678/05 In an axial flow rotary compressor a fluid n ow inlet is circumferentially separated from a fluid flow outlet by a dynamic flow splitter comprising at least one toroidal chamber providing a loop fluid flow path intersecting the path of the rotor blades such that any fluid leakage through the flow splitter flows around the loop flow path . Regeneration of the flow through the rotor blades as they emerge from the flow splitter is thus facilitated. The flow splitter may comprise a number of contiguous chambers whose apartures can increase towards the low pressure end of the flow splitter to compensate for the decreased density of the fluid. The downstream walls of the flow splitter chambers can be offset relative to the upstream walls so as to provide a direct quasihelical fluid flow path through the flow splitter to increase the enthalpy transport through the flow splitter.
