BIROTATING MECHANISM Russian patent published in 2024 - IPC F02B53/00 F01C1/22 

FIELD: machine building.

SUBSTANCE: birotating mechanism includes hollow housing (1) with side cover (2) and driven rotor (3) located in it, consisting of hollow drum (4) with inner working surface (5) formed by circular arcs, and with seals (6) along periphery. Design and arrangement of drive rotor (7) and its sealing are disclosed. Seals (6) of drum (4) on periphery are contactless labyrinth seals. Mechanism is equipped with an additional shaft installed on bearings with a square part rigidly connected to driven rotor (3) and located parallel and with eccentricity with shaft of drive rotor (7), made with additional guide slot for placement in it of square part of additional shaft of driven rotor (3). Invention covers the guide slots. On the inner surface of driven rotor (3) there are diametrically opposite located tides with a flat surface perpendicular to the plane passing through the centres of rotation of the shafts of rotors (3, 7) and having a length of at least S=2e+t, where e is eccentricity of rotors in their centres of rotation; t is width of radial seals located in tops of drive rotor (7).

EFFECT: higher reliability of radial seals.
