ROTARY MACHINE Russian patent published in 1999 - IPC

FIELD: mechanical engineering; internal combustion engines, pumps and compressors. SUBSTANCE: rotary machine has housing, operating shaft, two rotors with four blades, differential mechanism and brake mechanism. Blades of one rotor are fitted between blades of other rotor, thus forming eight chambers. Differential mechanism is installed in center of housing and is coupled with operating shaft to provide alternate movement of rotors at constant rotation of shaft. Brake mechanism is secured on shaft from outer side. Blades do not touch stator. EFFECT: reduced wear of blades owing to elimination of fraction. 8 dwg
