Abstract:
A multi flame-ring gas burner for cooktops includes a lower burner body configured to receive at least two injectors facing Venturi ducts; a first burner base with a first cap and with openings for a central flame ring; and a second burner base with a second annular cap and openings for an outer annular flame ring. The lower burner body has a seat for a spark plug interacting with the first burner base; two cylindrical seats having substantially horizontal and parallel axes accommodating two tubular elements internally shaped like linear Venturi ducts; and a substantially tubular portion projecting upward, the first burner base being integral with the projecting tubular portion. An injector-holder unit is applicable to the lower burner body and has two portions that are removably insertable into corresponding through holes in the lower burner body and facing the tubular elements internally shaped like linear Venturi ducts.

Claim (Index 1):
A multi flame-ring gas burner for cooktops, comprising:\n a lower burner body ( 2 ), which is mountable on a metal sheet ( 48 ) of a cooktop and is configured for application of at least two injectors ( 60 ,  62 ) facing respective substantially horizontal, linear Venturi ducts ( 42 ,  44 ) that are provided in said lower burner body ( 2 ); and a first burner base ( 4 ) with a first circular cap ( 8 ) and provided with openings ( 30 ) for release of a central flame ring, and a second burner base ( 6 ) with a second annular cap ( 10 ) and with openings ( 72 ), which are provided in one or both of said second burner base ( 6 ) or said second annular cap ( 10 ), for release of at least one outer annular flame ring, said first and second burner bases ( 4 ,  6 ) being in fluid communication with the respective Venturi ducts ( 40 ,  42 ), wherein said lower burner body ( 2 ) is made in a single piece and is provided with: a seat for mounting a spark plug ( 32 ) interacting with said first burner base ( 4 ), the two linear Venturi ducts ( 42 ,  44 ) having substantially parallel axes, and in a substantially central position and at an upper surface thereof, a portion ( 28 ) having a tubular extension and projecting upward, and wherein: said first burner base ( 4 ) is integral with said projecting tubular portion ( 28 ) of said lower burner body ( 2 ), at least one injector-holder unit ( 52 ) that is made separately from said lower burner body ( 2 ) and is removably constrained to said lower burner body ( 2 ) is provided with two portions ( 54 ,  56 ), which are removably insertable into corresponding through holes ( 20 ,  22 ) obtained in said lower burner body ( 2 ) in a position facing said Venturi ducts ( 42 ,  44 ), each of said Venturi ducts ( 42 ,  44 ) communicates upstream with a first chamber ( 16 ,  18 ), which carries an injector ( 60 ,  62 ) applied to a wall, communicates with an exterior for sucking primary air, and communicates downstream with a second chamber ( 40 ,  24 ) in fluid communication with one of said first and second burner bases ( 4 ,  6 ), and at least one of said Venturi ducts ( 42 ,  44 ) is made separately from the lower burner body ( 2 ) and consists of an externally cylindrical tubular element configured to be accommodated in a corresponding cylindrical seat ( 36 ,  38 ) obtained in the lower burner body ( 2 ) coaxially to the circular through hole ( 20 ,  22 ) which accommodates a part of injector holder ( 54 ,  56 ), to which the respective injector ( 60 ,  62 ) is applied, said Venturi duct ( 42 ,  44 ) being insertable into the cylindrical seat ( 36 ,  38 ) of said lower burner body ( 2 ) through said circular through hole ( 20 ,  22 ) and being lockable in a desired axial position with a locking element ( 46 ) adapted to be actuated from above the lower burner body ( 2 ) when applied to the cooktop.
