DEVICE OF STABILISATION OF AIR FLOW RATE Russian patent published in 2015 - IPC F24F13/08 

FIELD: ventilation.

SUBSTANCE: device of stabilisation of air flow rate comprises a housing 1 with a regulating valve in the form of a stationary disc with slots 2 and a rotating disc 3 with mating slots and a rotation stopper 4. The rotating disc 3 is attached to the common axis 5 with an impeller 6 receiving the pressure of inlet airflow. The axis 5 rests on the stationary disc with the slots 2 and the rack 7. The angle of rotation of the impeller 6 is regulated by tension of the elastic element 8 fastened with one end on the axis 5, and with the other end on the tension adjustment screw 9 of the elastic element 8. The adjustment screw 9 is mounted on the rack 7. The proposed design of the device of stabilisation of air flow rate can be incorporated into the channels of arbitrary orientation in space, including in a horizontal channel.

EFFECT: ability to work without energy consumption from an external source.
