ROTOR MACHINE Russian patent published in 2008 - IPC F01C3/02 

FIELD: engines and pumps.

SUBSTANCE: rotor machine incorporates a stator, tightly closed on both end faces and furnished with an inlet and an outlet, a movable partition with a cut arranged in the stator so as to revolve therein, variable inner chambers, and a rotor representing a body of revolution with the vanes and linked with the aforesaid partition so that the vanes enter the aforesaid partition cut. The partition cut section along the revolution circumference represents a parallelogram. The rotor vane cross section represents a polygon with two equal sides interacting with the stator end face surface. At least, one polygon angle adjoining each of the aforesaid sides is equal to the blunt angle of the aforesaid parallelogram. The contact between the stator inner surface and movable partitions, as well as that between the stator inner surface and the rotor body and that between the partitions and rotor vanes is sealed.

EFFECT: tight movable "rotor vane-partition" joint, rotor machine higher efficiency.
