AIR FLOW STABILIZER Russian patent published in 2019 - IPC F24F13/00 F24F11/75 

FIELD: ventilation.

SUBSTANCE: stabilizer relates to building ventilation systems, in particular to natural exhaust ventilation. Air flow stabilizer comprises housing, cylinder with slots in side surface, fixed in housing by means of diaphragm, and plunger installed with possibility of reciprocal movement in cylinder, wherein the stabilizer is equipped with a chain of links with elastic elements with given linear stiffness characteristics, each of the links comprises a base plate, on which by means of retainers are fixed limiters movement of a separate elastic element, one end of each resilient element is fixed on its base plate, to the other end of each resilient element by means of a retainer is connected a rod connecting it by means of a retainer to the base plate of the next link in the chain, the plate of the base of the first link of the chain of elastic elements is rigidly fixed to the housing of the stabilizer; on the opposite side of the chain of links the last rod is attached to the plunger of the stabilizer by means of a retainer.

EFFECT: simplification of design, as well as elimination of spatial orientation of air flow stabilizer, operation without external power source, possibility of integration into channels without protruding parts of device.
