MULTI-STAGE ROTOR-SWIRL MACHINE WITH COMBINED STATORS Russian patent published in 2008 - IPC F04D5/00 F01D1/02 

FIELD: engines and pumps.

SUBSTANCE: machine casing accommodates a stack of stages with inlet and outlet channels of adjacent stages communicating between themselves. Every stage incorporates a rotor fitted on the shaft and a stator fixed in the casing. A working chamber is formed between the rotor and stator of every stage housing the blades coupled with the stator and a separator coupled with the rotor. The stator of every stage is made in the form of disk. The stators of the extreme stages are furnished with the working medium inlet and outlet channels. Every stator of intermediate stage incorporates a channel to allow passage of the working medium from one stage into another. Every stage is furnished with a spacer sleeve to make a gap between adjacent stages stators to accommodate the rotor therein. A circular channel is provided between the rotor and the spacer sleeve. Every rotor has the channels to communicate the working chamber with the inlet and outlet channels.

EFFECT: higher machine efficiency and smaller labor input in stator processing.
