SPIRAL MACHINE OF CONTROLLED OUTPUT Russian patent published in 2011 - IPC F04C18/02 F04C28/10 

FIELD: machine building.

SUBSTANCE: spiral machine consists of case 1 with suction and pressure orifices 4 and 5; also case is made of two parts. The machine further consists of immobile spiral element 6 and mobile spiral element 7 inter-engaging and arranged between two parts of the case. Element 7 has no base and is mounted on eccentric shaft 12; it performs orbital motions with eccentricity relative to element 6, thus creating closed compression cavities. The machine consists of drive anti-rotary device 8. To facilitate control of output one part of case 1 with suction orifice 4 corresponds to rotary element 2 with suction channel 3 made as recess, facing elements 6 and 7 on surface of rotary element 2. Suction channel 3 has a shape ensuring closure of part of cavities volume between elements 6 and 7 actuated in process of pressurising at turn of rotary element 2 into one side and opening part of the said volume of the cavities at turn of this element into another side, thus controlling output.

EFFECT: increased output of operation, reliability and service life of spiral machine.
