FIELD: mechanical engineering; pumping building.
SUBSTANCE: proposed rotary machine 10 with radial pistons 19 has bearing 29 with rotating thrust race 28, fixed outer race 30 and rollers 31 placed in between Thrust race 28 one contact device 43, 45 for each piston 19, thus providing straight-line travel in second direction along second axis b perpendicular to first longitudinal axial line a of piston 19. Distributing device 15 is installed for movement in space limited by cover 12 and coaxially to rotor 17 owing to bearing means C2, C3. Distributor can freely move in all directions.
EFFECT: increased efficiency and prevention of contamination by particles getting together with oil owing to prevention of contact of surfaces of rotor and distributing device.
