Abstract
A device is divulged for controlling and regulating the gas supply to the burner of a boiler or similar, which device comprises a piloted regulator (R) with a leak valve (8) for the gas flow. The burner is also fed with pressurized air and opening of the leak valve is slaved to the flow of this pressurized air so that the ratio between the two air and gas flows permanently has a value providing excellent combustion of the air-gas mixture in the burner.
