The invention relates to a mechanism designed for the artificial draught of gases, which mechanism is composed of a cylindrical or polygonal tube bearing ports (Γ) being parallel to the axles (Δ) of the cylindrical or polygonal tubes which are spaced apart and closed at the top. The invented mechanism does not bear moving parts. The Bermulli-Venturi principles created by the shape of the mechanism lead either to the creation of draught or to the significant reinforcement and stabilization of the natural draught; pumping of air and exhausts is equally ensured by said mechanism which finds application, in particular, to chimneys and stoves and can be used as a means for the ventilation in spaces where aeration is difficult (e.g. warehouses, skylights etc). Throughout the operation of the invented mechanism, the drought is continuous no matter the weather conditions may be. |
