AIR FLOW STABILIZER Russian patent published in 2023 - IPC F24F13/08 F24F11/00 

FIELD: natural exhaust ventilation.

SUBSTANCE: stabilizer refers to ventilation systems for buildings for various purposes, in particular to natural exhaust ventilation. The air flow stabilizer contains a housing 1, a diaphragm 2 fixed in the housing, a plunger 3 that perceives the pressure of the air flow, mounted on an axis 4, with limiters 5 at one end and at the other end, moving back and forth in bushings 6 mounted on racks 7-1, 7-2, one of the racks 7-1 is fixed in the housing 1, the stabilizer is equipped with a sequence of elastic rods 8-1… 8-3 with given linear stiffness characteristics, each rod can touch the protrusion 9 on the axis 4 when it moves. A smoothly tapering channel 10 is attached to the housing 1, a smoothly expanding channel 11 is attached to the diaphragm 2. Another rack 7-2 is fixed in a smoothly expanding channel 11. The other ends of each elastic rod (8-1… 8-3) is fixed in a smoothly expanding channel 11.

EFFECT: eliminating the spatial orientation of the air flow stabilizer, the ability to be built into channels without protruding parts, the ability to operate without an external energy source, the presence of a composite elastic element that meets the required stiffness characteristic, and is more sensitive to the low speed of the oncoming air flow.
