Abstract
A combustion chamber assembly unit, for a fuel-operated vehicle heater, includes a combustion chamber housing () with a combustion chamber () defined by a circumferential wall () and by a bottom area (). A flame tube () follows the circumferential wall () in the direction of a housing longitudinal axis (L) and encloses a waste gas flow space () that is open in the direction of the housing longitudinal axis (L). A flame diaphragm () has a flow-through opening (). A waste gas backflow space () is formed between the flame tube () and a housing () enclosing same. The waste gas flow space () is open towards the waste gas backflow space () in a first axial end area () of the waste gas backflow space (). A catalytic converter device (), through which combustion waste gases can flow, is provided in the waste gas backflow space ().
