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

FIELD: natural exhaust ventilation.

SUBSTANCE: air flow stabilizer comprises a housing, a diaphragm fixed in the housing, a plunger that perceives the pressure of the air flow, fixed on the axle, with limiters at one end and at the other end of the axle, with protrusion 13 on the axle, moving reciprocating in bushings mounted on racks, fixed in the housing. The stabilizer is equipped with a block of elastic rods, the elastic rods with specified stiffness characteristics are placed in the channels of the block. Each elastic rod has a slider capable of moving along the elastic rod in the channel of the block. The required (adjustable) position of the slider is fixed with a retainer. At one end, each elastic rod is fixed in the block of rods, and on the opposite side it can touch the protrusion on the axis when it is moved.

EFFECT: using, instead of a sequence of elastic rods with given stiffness characteristics, a block of elastic rods with rods of given stiffness characteristics with the possibility of adjusting their stiffness, as well as eliminating the spatial orientation of the air flow stabilizer, operation without an external energy source, the possibility of embedding in channels without protruding parts of the device.
