ROTARY-VANE MACHINE Russian patent published in 2001 - IPC

FIELD: mechanical engineering; rotary-vane engines, pumps, compressors, hydraulic drives. SUBSTANCE: rotary-vane machine has fixed housing accommodating rotating vane rotors. Rotors rotate at variable velocity thus cyclically changing volumes of housing divided by rotors. Rotors are secured on coaxial shafts furnished with carriers on free ends. Mechanism providing periodical change of velocity and synchronization of rotation of rotors and output shaft is made in form of carrier installed on inner end of output shaft. Carrier has gear wheels freely rotating on axle-shaft of disks of which axle-shafts are installed. Mechanism has also fixed gear wheel getting in meshing with these gear wheels. Carriers on ends of shafts with rotors are provided with radial slot through which axle-shaft installed on gear wheel disk passes. EFFECT: provision of easy transmission of torque from rotors to output shaft, reduced vibration. 3 cl, 5 dwg
