Abstract (en)
[origin: EP2186545A1] The device has a cylindrical tube (3) whose outlet is spaced from another cylindrical tube (1a). Air intakes are placed at an end of a nozzle spout (1) located upstream from the outlet of the former tube relative to a direction of propagation of a premix. Divergent and separate jets of the premix are connected to an internal surface of the latter tube. Outdoor air is made to pass on an outer surface of the jets. Divergence and separation of the jets causes sucking of the outdoor air towards interior part. The connection of the jets forms a closed premix volume into which the air is sucked.
