ROTOR MACHINE Russian patent published in 2010 - IPC F01C1/00 

FIELD: machine building.

SUBSTANCE: rotor machine of volumetric type consists of case 1 with supplying channel 11 and withdrawing channel 15 of working medium, of central element 4, and also of profiled element 2 and wheel-divider 5 shutting off working channel. Element 4 is installed in an internal cavity of case 1 with a gap relative to a wall of case 1 thus forming a circular working channel. Wheel-divider 5 is installed in the internal cavity of case 1 between the wall of case 1 and element 4; the wheel rotates around its axis and has recess 8, surface of which is technologically conjugated with a response surface of element 2. Element 2 is made as single with case 1 in form of a lug on its internal wall. Element 4 is hollow; its internal cavity communicates with the circular working channel and channel 11 of working medium supply and has rotary valve 10 for adjustment of working medium supply to the circular working channel. Case 1 and/or central element 4 rotate around their axes. Case 1 is kinematically tied with wheel-divider 5, rotation axis of which is in one plane with rotation axis of element 4.

EFFECT: increased efficiency of rotor machine operation, simplification of design.
