HYBRID VENTILATION DEVICE MADE WITH POSSIBILITY OF NATURAL AND FORCED VENTILATION Russian patent published in 2016 - IPC F24F7/13 

FIELD: ventilation.

SUBSTANCE: in case of the natural ventilation there is the possibility of worm gear rotation in normal direction by driven force of the drive unit controlled by the control unit such, that the pressing element interacts with the guide shoulder to guide the rotation, and rotates the shutter, thus ensuring the channel opening for the flow, and then the worm gear rotates back by the driven force of the drive unit to return the pressing element to initial position, thus ensuring possibility of the roller rotation by the user upwards and downwards, and shutter rotation such, that degree of the channel opening for the flow can be regulated.

EFFECT: possibility to lock quick supply of the ambient air, and prevention of cold transition, when the air temperature in the room quickly decreases.
