Abstract

A mixer device for burner equipment includes flow guide means for guiding an air-gas mixture to the intake of a fan rotatable about a first axis, the guide means including a tubular Venturi effect conduit structure with axially symmetric contiguous converging and diverging portions about a second axis, a section being provided between the portions of conduit into which the gas flow is delivered for mixing with the air flow supplied through the converging portion. The fan's axis of rotation does not coincide with the axis of longitudinal development of the Venturi effect conduit, the offset between the first and second axes allows placement of a valve which supplies the gas flow into the Venturi effect conduit with a configuration in which the projection of the overall dimensions of the Venturi effect conduit and of the valve unit, in the rotational axis direction, lies within the fan's cover plate projection.
