FIELD: mechanical engineering. ^ SUBSTANCE: invention can be used in internal combustion engines, pumps, compressors and other positive-displacement machines. Proposed positive-displacement rotary machine contains two coaxial rotors with blades, each being mechanically coupled with uniformly rotating shaft by means of four-link members providing non-uniform rotation of rotors in antiphase. Machine is furnished with two units of four-link members intermediate supports of which are connected and made eccentrically with possibility of displacement for changing eccentricity between rotating axles of four-link member. Angle between driven crank of first unit of four-link member and driving crank of second one is from 0 to 180 degrees. ^ EFFECT: enlarged operating capabilities of machine owing to transmission of all forces by surface contacting. ^ 5 dwg |
