Abstract
The device consists of a rotor (4) which is arranged in a suction pipe (1) and rotatably supported. The rotor (4) includes a hollow jacket body (5) on the outer wall of which vanes (2, 3) are arranged. A nozzle holder (26) is guided through the end (10) of the jacket body (5) directed against the air stream, which holder bears the injection nozzle (9) and is connected at the rear end with the fuel feed line (8). The fuel jets (24, 25) coming out of the injection nozzle (9) are directed against the inner wall (20) of the jacket body (5). This forms, at the same time, the jacket surface of the core hollow space (6) which widens toward the open end (11) of the jacket body (5). At the open end (11) is a centrifuge ring (14) with a spray edge (23). The rotor (4) is set in rotation by the stream of air flowing in the direction of the arrows (30, 31), and mixes the fuel centrifuged from the spray edge (23) homogeneously with the air. A measuring probe (28) determines the rpm of the rotor (4) and controls the influx of fuel through a pump to the fuel feed line (8) and thus to the injection nozzle (9).
