PLANETARY ROTARY VOLUMETRIC MACHINE Russian patent published in 2021 - IPC F01C1/14 F04C18/14 F04C25/02 

FIELD: volumetric machines.

SUBSTANCE: invention relates to volumetric machines and namely to vacuum pumps, compressors. The machine contains a rotor 1, made in the form of a non-circular wheel with external teeth, a stator 2, made in the form of a non-circular wheel with internal teeth, interacting with the stator 2 and the rotor 1 circular floating satellites 3, stationary end walls 4 and 5, as well as a system of supply channels and outlet 7 and 12 of the working environment. The centroids of the rotor 1 and stator 2 have the same number of sections of the upper stand of the satellites 3, which are circles of the maximum radius, the same number of sections of the lower stand of the satellites 3, which are circles of the minimum radius, and the transition sections located between them, providing a smooth transition from the maximum radius to the minimum. The angular extent of each transitional segment of the centroid is set at a certain interval. The angular extent of each section of the minimum radius is equal to the angular extent of each section of the maximum radius and is given by a certain ratio. The average centrifugal force of inertia acting on the satellite 3 depends in a certain way on the maximum force of the medium pressure on the satellite 3.

EFFECT: invention is aimed at increasing the compression ratio of the working medium.
