Description

Method for feeding a combustion chamber with liquid fuel under pressure by an atomizer. The invention relates to a method of eating one; Veri-rennungsrauines with liquid Brenastof under pressure by an atomizer, in which the fuel undergoes a circling or whirling motion. uni the 'The innovation in # i4e_ # a procedure is that there is a controllable part of this; lein Fuel supplied to the atomizer is returned from a point in front of the outlet nozzle will.

The device for carrying out the 'driving: lienende' device for this purpose a fuel return line connected to the swirl chamber of the atomizer. Instead of draining all of the oil that has got into the chamber through the mouth, beer becomes part of the Üis of rfer chamber a1>, re; enkt lind; lein Punipentinter # Irttcl: z.; iguided. so ..1a13 the real injection line @ _e 1e only vcni \ -erliälni: four aüzelenkten (i: a; en @ e zurge: antInietige c: es in rIen Brenner succeeded # "encIen (as depends.

The mode of operation of this atomizer :, is as follows: Fuel is pressurized through the bore 31 and goes through the chamber 30 into the annular grooves 3, through the channels 13 in the head -9 of the block 8 into the annular groove i 8 and through the tangential grooves 17 into the chamber 15 of the cap 14. get zti, where he as a result of cl-er tangential la; " e #ler grooves 17 hurry to circle, ae or whirl; the movement assumes.
