FIELD: mechanical engineering.
SUBSTANCE: invention relates to rotary piston machines of displacement type and it can be used in pumps, compressors, engines. According to first design version, device contains stator, rotor installed eccentrically in stator. Planetary mechanism consists of larger and smaller gear. Larger gear is fixed with meshing outside smaller gear made for rolling over larger gear of planetary mechanism. Stator is coupled with larger gear, and rotor, with smaller gear. Equations describing contours of rotor and stator are provided. According to second design version, device contains stator and rotor. Smaller gear is installed stationary, and larger gear is made for rolling over smaller gear of planetary mechanism. Stator is coupled with smaller gear, and rotor, with larger gear. Equations describing contour of rotor and stator are provided.
EFFECT: increased efficiency and specific characteristics of capacity and power.
