Abstract (en)
[origin: WO03092875A2] An air-gas mixer device, particularly for gas burners with forced ventilation, comprises an air-gas mixing chamber (18) supplied by a gas-flow and by an air-flow which are directed in the device through a first duct (3) and a second duct (4), respectively, first means for choking the second duct (4) in order to choke the air-flow admitted to the mixer device through the second duct, air-flow diverting means (9) for separating and directing the choked air-flow into a primary air-flow and a separate and distinct secondary air-flow, as well as second choke means associated with the secondary air-flow so as to direct the secondary air-flow selectively towards the mixing chamber (18).
