  • Patent number: 6793487
    Abstract: A burner, in particular, for a motor vehicle supplementary or parking heater, for the burning of liquid fuel, in the presence of combustion air, has a combustion chamber (10), with a jet for the atomization of liquid fuel, arranged before said chamber. The jet has a Venturi tube (11) at the largest diameter end of the diffuser section thereof, opening into the combustion chamber (10), and the liquid fuel is introduced into the Venturi region which is at a low pressure when compared with the upstream end of the diffuser section (12), and through the inlet section (13) of which the air is pumped.

  • Publication number: 20030022123
    Abstract: The invention relates to an atomizing burner, especially for use in an automobile auxiliary heating system, comprising an atomizing nozzle (2) for processing the fuel, an ignition device (29) and a combustion chamber (8). An iar conduction device (10, 12, 14) is connected upstream of a nozzle holder (3) of the atomizing nozzle (2) in order to achieve finer atomization of the fuel. Said air conduction device subjects the combustion air streaming into the atomizing nozzle (2) to a swirl.

  • Patent number: 4519772
    Abstract: A heating device fed with free-flowing fuel and connected to an on-board voltage source, in particular, a vehicle heater. The heating device is equipped with a burner assembly which has a fuel supply, a combustion air fan and a heating element which ignites a fuel/air mixture after a preheating phase. During the preheating phase, the combustion fuel fan is shut off or at least is operated at less than the operating blower output. There is also a switching device which automatically turns on or switches the combustion air fan to its operating blower output after a preheating phase has been completed. The switching device is designed as a voltage-dependent time-function element, which presets a preheating time dependent upon the magnitude of the on-board voltage and which decreases the preheating time as the on-board voltage increases.

  • Patent number: 4395225
    Abstract: A burner for use with liquid fuels in heating devices, especially vehicle heaters, as a low pressure atomizer arranged at one end of a combustion chamber that includes a burner insert and a nozzle projecting into an end of the burner insert that faces away from the combustion chamber, and a supply means for feeding a fuel and a primary air stream into the nozzle, at least the quantity of primary air passing through the burner being controllable automatically by a flow control valve and arrangement in dependence upon the temperature of the burner. Additionally, in accordance with preferred embodiments the flow control valve arrangement may be either a bimetallic ring or a bimetallic strip which opens or blocks off the passage of air in dependence on the temperature. In addition to controlling the primary combustion air, controlling of secondary air is also provided.
