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.

Abstract: A thermostat for cooking appliances powered by gas includes a body defining an inlet conduit and an outlet conduit that receive a gas flow from a supply source and to supply it to a gas burner, and a chamber having a substantially cylindrical shape that is in fluid communication with the inlet conduit, and also with the outlet conduit either directly, through a main opening formed at one end thereof, or indirectly, through a secondary conduit formed in the body of the thermostat. The gas flows into the outlet conduit bypassing the main opening. A one-piece valve adjusting the gas flow rate is coaxially fitted in the chamber and guided by its peripheral walls. These features make the structural configuration of the thermostat body and its conduits is much more compact, functional and less expensive than in thermostats known in the art.
