CIRCUMFERENTIAL MACHINE (OPTIONS) Russian patent published in 2018 - IPC F01C1/344 F01C3/06 F04C2/344 F04C3/06 

FIELD: machine building.

SUBSTANCE: group of inventions refers to the field of engineering and can be used as a turntable, propeller, pump or expander. Circumferential machine comprises an outer and inner contour 1, 2 of the rotation bodies and at least one locking element 3. Each body of rotation contains at least one part of the sphere. Contour 2 is located in contour 1 with the possibility of its rotation relative to contour 1 so that their axes 8, 9 are inclined relative to each other, and the centers of symmetry coincide, and between them are formed two working cavities 4.1, 4.2, in each of which there is input 5.1, 5.2 and output 6.1, 6.2. Each element 3 is mounted in contour 2 with the possibility of mutual movement relative to each other and rotation relative to contour 1 and is capable of dividing each cavity 4.1, 4.2 into its high and low pressure zones and moving the working fluid in each cavity 4.1, 4.2 from input 5.1, 5.2 to output 6.1, 6.2. Contour 2 creates sealing points along the inner surface of contour 1, and element 3 – along the inner surface of contour 2 and in the places of installation in contour 2.

EFFECT: group of inventions is aimed at increasing the specific power while simplifying the design.
