GAS BURNER FOR FOOD COOKING

The invention refers to a gas burner for cooking appliances, of the type which can be used with gases of different kinds; the main characteristic of the burner is that the flame separator element, to which a cover (4) is superposed, is integrated in the head (1) of the burner, made of a single piece with it, and provides for different orifices, for the exit of the air-gas mixture, disposed in two rings, an upper one (3; 9) and a lower one (2;10), in that a first series of said orifices (2;9), provided for supplying main flames, have a section such that the exit speed of the mixture is higher than the combustion speed of the most critic type of gas and in that a second series of said orifices (3;10), provided for supplying pilot flames, have means (5;11) to reduce the exit speed of the mixture, so that it results in being minor in respect of the exit speed from the orifices of the first series, in order to stabilise said pilot flames and, as a result, the main flames.
