AIR VENT DEVICE (AVD) Russian patent published in 2021 - IPC F24F7/02 

FIELD: ventilation systems.

SUBSTANCE: invention relates to ventilation systems, in particular to devices for natural ventilation. The air vent device contains a cylindrical nozzle with a curved diffuser and a control element with a cone-shaped surface mounted with the possibility of axial movement relative to it, repeating the shape of the diffuser, and the possibility of placing a conical streamlined element, coaxially with the control element associated with the latter, while the regulating element is made in the form of a body of revolution (1) with coaxially located conical surfaces (2) and opposite tops, while one of the conical surfaces (2), located on the side of the diffuser (3), repeats the curvilinear shape of the latter, and the other is made streamlined, and the longitudinal section (4) of the body of revolution (1) by the plane in which the longitudinal axis of the body of revolution (1) is located includes two pairs of opposite vertices (5), one pair of which intersects the longitudinal axis of the body of revolution (1), which has the possibility of axial movement relative to the diffuser (3).

EFFECT: creation of a design variant of the air outlet device with a simpler design and high performance is provided.
