Abstract: A fuel-operated vehicle heater especially of the type intended as an auxiliary or additional vehicle heater and which has a nozzle sitting on a nozzle holder to which fuel is fed from a fuel line by a filter, a fuel pump and an interposed solenoid valve. In a preferred embodiment heater, the nozzle holder, fuel pump, filter and solenoid valve form a subassembly that can be handled as a single unit. Advantageously, this subassembly can be fastened by screws to a flange within a housing part of the heater. On this flange can also be fastened an ignition spark emitter an a central connecting device, such as a burner motor. Advantageously, the feed line and/or the return line for the fuel supply are formed in the flange.

Abstract: A connecting device for supplying power to equipment in heating devices, particularly, auxiliary vehicle heating devices, which connecting device serves to commonly and centrally supply a combustion motor, a control device, a circulating pump, a solenoid valve, an ignition spark unit, a flame monitoring device, and, if utilized, a preheating device for a burner nozzle assembly. All connections and connecting devices, like plug connectors, are housed and combined in a common, central connecting component which can be secured on a flange of the heating device, and can be attached to a part of the heater housing. Appropriately, the connecting component is designed in the form of a housing and contains the electrical connections to be actuated in the form of printed circuit boards, or the like.

Abstract: A heater, especially a fuel-operated vehicle heater, is provided with a cylindrical insert that supports the flame in a combustion pipe delimiting the combustion chamber of the heater. The insert is arranged in such a way that an annular space is formed between the inside wall of the combustion pipe and the outer wall of the insert by the insert being located concentrically in the combustion pipe so as to project into the combustion chamber. This insert permits a concentration of the flame in the combustion chamber in the proximity of the burner of the heater, resulting in a burning under more favorable conditions and in a more complete burning.
