Description

Injection carburetor. The present invention applies to a >> spray carburetor, at what inflow of air and fuel at the same time regulated in this way is, @ let the mixing ratio ininier .las remains the same.

The novelty of the invention lies in the fact that the spray nozzle on a displaceable cone, which in connection with your @ -ent, iirirolir the air supply regulates and is attached to a piston, in -essen -litte Channel for the fuel supply to the spray nozzle is located.

The drawing shows an example embodiment of the object of the invention shown.

Fig. I shows a section through the carburetor in the rest position and Fig. 2 shows a section in the working position. The carburetor consists of a base part i, which is provided with a fuel line 2, 3. This line opens into a central bore in which a long piston a. can slide. This piston 4 is articulated at 3 to a double-armed lever 6, which can rotate at 7 about a lever 8 articulated at 9. A wire pull is provided on the lever 6 and is connected to the speed pedal or some other organ. On the circumference of the piston 4 there is an annular incision 4 # @ and an upwardly directed longitudinal groove 4 P connected to it . Above the incision. -A there is a second rising channel 4a of increasing cross-section, which is connected to a channel 4d arranged centrally in the piston, which in turn leads to the spray nozzle. The spray nozzle ii is screwed into your upper part of the piston 4 and in a recess i2a a cone 12, which is also screwed onto the upper part of the piston 4. The position of this bonus can be adjusted with the aid of a screw 13. Between this screw 13 and the upper part 1s of the bottom part i, a spring 14 is arranged which holds the piston and the Ison us in the rest position. The Gherwurfinutter 15 sits on your part i, wol: ei a sealing ring 16 is arranged between it and the part i. The same seal 17 is produced on the lower part of the Körliers i with the aid of a union nut 18.

In part i there is also a pinnacle, yes, its upper part with the channel 3 in connection and which extends downwards upright. if the cone 12 closes the double funnel i9 (Fig, i), the ring-shaped one is located Incision of the piston; 4 at the same height as the channel 3. The cone 12 supports against a seat in the lower part of the double funnel i9. This is in yours Carburetor pipe 2o, which distributed below the funnel over its entire Ulmfang Contains air inlet openings 2oa.

The mode of operation of this carburetor is as follows: Is the When the piston is in the lower position (Fig. 2), the fuel liquid entering at 2 occurs through the Kail.al 3, channel .tv, annular recess 4a, channel yes, channel .4c and the line .1.d to the spray nozzle i i.

Depending on how you open the cone 12 more or more, it becomes more or less air and fuel get to the mixing space, so that the mixing ratio between air and fuel always; remains the same

Claims (1)

PATENT CLAIM: Spray carburettor with which the inflow of air and the fuel! is controlled at the same time so that the mixing ratio always remains the same, characterized in that the spray nozzle (ii) is open a displaceable cone (12) sits, which in connection finitely with the Venturi tube (Double funnel i-.) Regulates the air supply and in turn on a piston (4) is attached, in the middle of a channel (4d) for the fuel flow to Nozzle is located.
