Abstract (en)

The invention produces a device for regulating the flow of combustion air supplied by a fan to a burner connected to a boiler, comprising: a damper (3) hinged to the body of said burner on the inlet of said combustion air; means of regulating connected to said burner and working together with said damper suited to varying its position to regulate the degree of opening of said inlet. Said means of regulating comprises at least one metal rod (5) whose end (51) presses against the damper (3) and that a given section of said rod is wound by an electric coil (9) powered by electric current when the combustion air fan is in operation, said rod (5) being magnetised so that the tip (51) of said rod ensures its contact with the damper by magnetic attraction. <IMAGE>
