ROTARY MACHINE (OPTIONS) Russian patent published in 2023 - IPC F01C3/08 F04C18/56 F04C29/00 F04C29/04 

FIELD: rotary machines.

SUBSTANCE: machine (20) contains case (55A) with a concave truncated-spherical inner surface, the first rotor with a convex truncated-spherical outer surface adjacent to the inner surface of the case, at least one blade limiting at least one recess, a center of the first rotor in a center of a radius of the outer surface of the first rotor, a hydrostatic bearing of the first rotor, formed on its outer surface. The hydrostatic bearing of the first rotor contains at least one fluid channel through its outer surface, a surface limiting a bearing pocket around a fluid channel of the first rotor, at least one first area around the first bearing pocket. The first area protrudes radially outward from the first bearing pocket relatively to the center of the first rotor. The first area is directly adjacent to the inner surface of the case with formation of a hydraulic seal in it.

EFFECT: group of inventions is aimed at a possibility of achievement of high compression degrees in a combination with high pressure at an outlet and high volumetric performance at a single stage.
