SPIRAL MACHINE Russian patent published in 2015 - IPC F04C18/02 

FIELD: machine building.

SUBSTANCE: spiral machine contains pair of spiral elements, each of them contains end disk and spiral. One of the spiral elements is made with possibility of movement with eccentricity e relatively to other element made fixed. The assembled spiral elements create at least pair of closed spaces between them. Angle of spiral twisting of the fixed spiral element exceed angle of spiral twisting of the movable spiral element by 180 degrees. Centre of end disk of the movable spiral element is displaced from centre of spiral in direction of the outside end of the spiral and at right angle to this direction towards the peripheral spiral turn, and its diameter is determined as per the equation.

EFFECT: improved specific characteristics of the spiral machine due to dimensions decreasing of the spiral machine casing upon its efficiency keeping.
