AIR FLOW STABILIZER Russian patent published in 2022 - IPC F24F13/08 F24F11/75 

FIELD: ventilation systems.

SUBSTANCE: stabilizer belongs to the ventilation systems of buildings for various purposes, in particular to natural exhaust ventilation. The air flow stabilizer comprises a housing 1, a diaphragm 2 fixed in the housing, a plunger 3, which perceives the pressure of the air flow, fixed on the axis 4, with limiters 5 at one end and at the other end, moving reciprocating in the bushings 6 mounted on the racks 7, fixed in the body. The stabilizer is equipped with a sequence of elastic rods 8-1 ... 8-3 with given linear stiffness characteristics. At one end, each elastic rod is fixed on the body, and on the opposite side it can touch the protrusion 9 on the axis 4 when it is moved.

EFFECT: simplification of the design, as well as the exclusion of the spatial orientation of the air flow stabilizer, the ability to work without an external energy source, the ability to be built into channels without protruding parts.
