Abstract
A heater (independent vehicle heater) which can be operated in a particularly wide range between full load and partial load, e.g., 1:10 to 1:15, is shown. This is achieved by the annular space surrounding the combustion chamber being divided into two partial compartments and by supplying the combustion air to these partial compartments. A control element (back-pressure-controlled control element), which separates some of the air passage openings between the annular space and the combustion chamber from the passage of air, is arranged in the combustion air line.
Claims4
A liquid fuel-operated vehicle heater arrangement, operated independently of a vehicle engine, the heater arrangement comprising:
- a combustion chamber formed with a wall with air passage openings, said combustion chamber having a downstream end connected to a flame tube for heat exchange;
- fuel supply means for supplying fuel connected to said combustion chamber;
- ignition means, connected to said combustion chamber, for igniting said fuel;
- means defining an annular space surrounding said combustion chamber wall air passage openings including a partition extending outwardly from said wall substantially at right angles to a longitudinal axis of said combustion chamber for separating said annular space into two compartments including an upstream compartment and a downstream compartment;
- a first air supply line connected to said upstream compartment and a second air supply line connected to said downstream compartment;
- and
- control element means for controlling flow of combustion air for supplying combustion air to at least one of said first air supply line and second air supply line.
