ROTOR BLOWER Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: controllable rotor blower comprises housing with the delivery passageway, two axially alined rotors with blades interacting with the housing to form working chambers of variable volume, input shaft, gear transmission with noncircular wheel, and capacity governor interacting with one of the rotors. One of the rotors is provided with an additional inertia mass, is mounted freely with respect the input shaft and its blades interact with the other rotor to form a periodically acting variable resistance. The capacity governor is made up as a delivery valve with a spring- loaded working member mounted inside the delivery passageway of the housing. EFFECT: enhanced efficiency. 2 cl, 5 dwg
