 element is blocked between the head and cup of the burner, once the head is rested and fixed on the cup, thereby allowing the functioning thereof for separating the burner inner space and as a result for obtaining one or more primary air inflow ducts and an equal number of reciprocally overlapped ducts for transferring the fuel mixture.
This solution, as afore mentioned, although allows to simplify the mould shapes for obtaining the head and cup of the burner, together with the fact also to ensure the realization of the separating element by simple shearing, it is not free of drawbacks.
As the Applicant has been able to verify, the efficiency of such a burner is somewhat reduced because of the turbulences that are created along the path followed by the fuel mixture inside the burner. This is also a consequence of the fact that the flows of air and fuel gas generated within the ducts for transferring the fuel mixture of the burner suffer from light leakages, which inevitably occur in burner itself.
Further, such leakages of fuel mixture, in the particular structure of the burner above described having the ducts for transferring the mixture overlapping the primary air flow ducts and kept apart from them by the afore said separating plane, involve as well the fact that the mixture eventually leaking from such transferring ducts is drawn, but only slightly, with the primary air towards the mixing chamber of the burner, where it results in an incomplete mixture of gas coming from the injector with the primary air, and then, again, in a reduced efficiency of the burner.
Object of the present invention is then to increase the afore described burner efficiency, thereby minimizing the turbulence of the fuel mixture and anyway maintaining unchanged the geometrical characteristics of the burner head and cup.
Further object of the present invention is also to obtain a burner being structurally simple and easy to assembly.

 As the Applicant has been able to verify, the efficiency of such a burner is reasonably reduced because of the turbulences that are created along the way followed by the fuel mixture inside the burner.

 Further, such leakages of fuel concoction, in the particular structure of the burner above identify take the ducts for transferring the mixture overlap the primary air flow ducts and observe apart from them by the afore said separating plane, necessitate as well the fact that the mixture eventually leaking from such transferring duct is drawn, but merely slightly, with the primary air towards the mixing chamber of the burner, where it result in an incomplete mixture of gas coming from the injector with the basal air, and then, again, in a reduced efficiency of the burner.
