ABSTRACT:
The annulus (20) around the fuel feed stud (8) which seals the rotor (14) of this central injection device is connected to a stowage compartment (40) for intake air by way of a ball bearing (7). In the case of the impeller (31, 35) driven rotor (14), the stowage air pressure counteracts the leakage fuel pressure in the annulus (20). By [adapting] adopting the width of the opening of the stowage compartment (40), the stowage air pressure is adjusted to be equal to or slightly higher than the leakage fuel pressure, so that no fuel can flow out of the annulus (20). [To enrich the fuel of the air-fuel mixture in the higher load range, a width of opening of the stowage compartment (40) is provided where the stowage air pressure at the corresponding RPM's becomes smaller than the leakage fuel pressure and the rotor (14) delivers additional fuel. ] A ventilating passage (42) connects the stowage compartment (40) with the annulus (33) which conducts the fuel discharged from the fuel outlet opening (16) to the spray ring (35) below the blades (38). [This ventilation ensures an undisturbed fuel delivery into the annulus (33). This injection device produces an air-fuel mixture in which the toxic constituents in the exhaust lie uniformly below the limit values and there are no high peak values for the toxic constituents.] When the rotor (14) is at rest, an internal fuel level "N" is established therein. During ingested air-driven rotation of the rotor, fuel is sequentially flowed through the fuel feed stud (8) downward across the at-rest fuel level, laterally through the rotor via an internal passage portion (17c) therein, upwardly through the rotor, via an internal passage portion (17d) therein, across the fuel level, and then outwardly through a lateral fuel outlet opening (16) into a concentric annulus (33). The fuel then flows downward through the annulus (33) to the spray ring (35) below the blades (38).
