|20130036839||FLAME ATMOSPHERE ANALYSER - A flame atmosphere analyzer is described, for operation with combustible gases, including a tube in which an intake and air and gas mixing chamber is formed, a first gas supply nozzle and means for supplying primary combustion air opening into said intake chamber, and a flame burner in fluid communication with the intake and mixing chamber for supplying an air and gas mixture, formed in the chamber, to the burner. The analyzer includes a second gas supply nozzle, which is slidably guided in the tube, and an actuator provided on the tube and operable from outside the tube, for moving the second nozzle between an inoperative first position, in which the gas is supplied through the first nozzle, and an operational second position, in which the gas is supplied through the second nozzle, the first nozzle having no effect on the supply of the gas in the second position.||02-14-2013|
|20100316967||BURNER, SPECIFICALLY A PREMIX GAS BURNER - What is described is a burner, specifically for gas fuels with premixing, comprising a burner body designed to be housed in a combustion chamber of a heating apparatus, the burner body being provided with a burner head on which an air and gas mixture supplied to the combustion chamber is burnt, in which the burner head has a surface profile in the form of a dome-shaped spherical segment, the height of the dome being less than half of the diameter of the sphere to which the segment belongs.||12-16-2010|
|20100018585||DEVICE FOR CONTROLLING THE DELIVERY OF A COMBUSTIBLE GAS TO A BURNER APPARATUS - A device for controlling the delivery of a combustible gas to a burner apparatus is provided including a main gas-delivery duct in which there is at least one servo-assisted diaphragm valve including a valve seat associated with a corresponding closure member with diaphragm control for opening the seat against the action of a resilient biasing member. The diaphragm valve includes a respective control solenoid valve with an electromagnetic operator for controlling the corresponding valve, the solenoid valve being arranged to bring about the opening/closure of a duct of a respective servo-assisted control circuit so as to operate the closure member of the valve indirectly, by the diaphragm control. The duct of the control circuit putting a portion of the main duct that is disposed upstream of the valve seat with respect to the direction of the gas-flow into flow communication with a respective control chamber of the diaphragm valve.||01-28-2010|
|20090101133||DEVICE FOR REGULATING THE AIR/GAS MIXTURE SUPPLIED TO BURNER APPLIANCES, IN PARTICULAR FOR BURNERS OF DECORATIVE FIRES - A device for regulating the air/gas mixture supplied to a gas burner appliance of a decorative fire is provided. The device includes a duct for supplying the air/gas fuel mixture to the burner and a choke of the flow of primary air taken into the duct and adapted to be mixed with the flow of gas or the flow of the air/gas mixture, in which heat-sensitive actuator acting directly on the choke is provided so that the choking of the flow is regulated automatically as a function of the heat level reached in the heat-sensitive actuator.||04-23-2009|
|20090035710||Automatic device for the ignition and control of a gas apparatus and relative driving method - Automatic device for the ignition and control of a gas apparatus comprising at least one burner for regulating the flow of gas from a main pipe towards a nozzle associated with the burner;||02-05-2009|
|20080268388||Device for Controlling the Delivery of a Combustible Gas to a Burner Apparatus - A device for controlling the delivery of a combustible gas to a burner apparatus is provided. The device includes a main pipe for delivery of the gas in which are disposed first and second servovalves in cascade with each other, with respect to the direction of flow of the gas. The servovalves include respective valve seats associated with corresponding shut-off means with diaphragm control for the opening of the seats. The first and second servovalves include respective first and second control solenoid valves with electromagnetic operating means to control the opening/closing of the corresponding servovalve. The solenoid valves are arranged to act to open/close the pipes of respective servo-assisted control circuits, so as to control indirectly, by way of the diaphragm control, the respective shut-off means of the corresponding servovalve the pipes of the control circuit placing the main pipe in fluid communication with respective control chambers of the servovalves.||10-30-2008|
