Volumetric rotary machine, which may be used as an internal combustion engine, compressor, pump, hydraulic and pneumatic engines. The machine has similar two-rib or three-rib rotors set between the casing's (1) working surfaces. The minimum numbers of three-rib rotors (2) is three, and two-rib rotors (3) are respectively three and four, excepting five. Every three three-rib or four two-rib adjacent rotors with their cylindrical surfaces form closed working chambers. The working chambers are restricted by the casing's working surfaces, from the sides of the rotors' face surfaces. Due to the kinematic relation, the rotors synchronously revolve in the same direction. During the revolving of the rotors working chamber volume periodically changes from zero to its maximum value and vice versa. The symmetry axis, perpendicular to the face surfaces of the rotor, is the rotation axis of each rotor. The rotors' rotation axes are parallel to each other and perpendicular to the casing's working surfaces. The distance of the adjacent rotors' rotation axes is equal to the radius of their cylindrical surfaces. The square of the distance of the rotation axes of the opposite two-rib rotors is the double square of the cylindrical surfaces' radius. |
