Abstract

A vaporizing combustion chamber for a heater running on liquid fuel, in particular a vehicle heater, in which inter alia two pipes disposed concentrically one inside the other form therebetween an annular chamber which is closed at a first end. At the second end, the annular chamber is open and leads into a flame diaphragm which projects radially inwards from the outer pipe and is located at a spacing in front of the inner pipe. At both its ends the inner pipe is substantially open and the opening at the second end is contracted by a concentric baffle edge of a baffle plate. In order to improve the emission values of the combustion chamber exhaust gas and reduce combustion noises both when the combustion chamber is disposed horizontally and when it is disposed vertically, the opening in the flame diaphragm is eccentric to the opening, in the inner pipe, formed by the baffle edge of the baffle plate. The radially larger wall surface of the flame diaphragm is in the vicinity of the fuel-introduction point on the periphery.
