ROTARY MACHINE Russian patent published in 2014 - IPC F01C1/63 F04C2/63 F04C18/63 

FIELD: machine building.

SUBSTANCE: proposed machine comprises cylindrical housing 1 accommodating two blades dividing said housing into four closed chambers and synchronisation mechanism composed by shaft 9 with solid spider offset from rotational axes of said blades. Spring-loaded shafts 10 with rollers 12 at their ends are fitted through holes in said blades. Discs 11 made integral with said shafts are arranged at the centre of said shafts. Attachment of shafts 10 with rollers 12 in contact with spider is executed by fitting the latter at two supports in blades. Discs 11 are shaped to square prisms with rounded vertices of rectangular faces whereat needle bearings are set and locked against axial shifts. Two split rings are fitted in grooves of said faces on both sides of the prism. Two covers 15 are arranged to prevent radial displacement and shaped similarly to square prism and locked against axial displacement by split rings fitted in the grooves of spring-loaded shaft 10.

EFFECT: decreased specific load and friction forces between contact surfaces.
