  • Injection apparatus for an atmospheric burner in a gas heating apparatus, especially of the infrared type, and heating apparatus provided with such an injection device
    Patent number: 5716203
    Abstract: The invention relates to an injection device for burner heating apparatus provided with an air/gas mixture conduit including a Venturi element. This injection device comprises an injector holding tube (14), secured to a valve body (15) divided internally into two chambers by a membrane (23): an idle chamber (24) subjected to the pressure of the gas and communicating with the injector holding tube (14), and a compensation chamber (25) set to atmospheric pressure, enclosing a spring (27) able to urge the membrane (23) toward an idle mode state. This injection device comprises further a rod (31) secured to the membrane (23) and associated with idle mode stop means (34), said rod being extended by a tapered needle (33) arranged to traverse the injector (13) and determine with the latter a cross-section for the idle mode gas outlet, when the pressure of the gas is less than or equal to the idle mode pressure.
