SPRAY-CARBURETER.
To all QUINN/'1, it may coma/1w Be it known that I, Max BUoHnRnR, a subject of the Emperor of Germany, and a resident of Cologne-on-the-Rhine, Germany, have invented certain new and useful Improvements in Spray-Carbureters for Explosive-Engines, of which the following is a specification- This invention relates to improvements in spray carbureters for use with explosive or internal combustion engines in which besides the main nozzle an auxiliary nozzle is provided. The main nozzle or the main spray nozzle, respectively, is connected in the cus-' toinary manner with a receptacle containing the liquid fuel as well as a float in the same, this liquid fuel is under atmospheric pressure. however, the liquid fuel for the auxiliary nozzle contained in a second receptacle, also provided with a float is under a dlfier- -ent pressure from that prevailing in the suction pipe. Besides these two nozzles, a third nozzle is provided which is connected with the atmosphere. The exit port of the auxiliary fuel nozzle, or spray nozzle is arranged .over the exit port of said third nozzle or air nozzle, corresponding to .the nozzle arrangement of an inhalation device, so that the jet of airescaping from the last mentioned nozzle under the sucking action of the motor sucks like an injector from the auxiliary nozzle a corresponding quantity of additional fuel. This arrangement offers the great advantage that the carbureter works with two fuel nozzles which are entirely independent from one another, one of whichhowever, the auxiliary fuel nozzle. is regulated with respect to the quantity of fuel it supplies, because the pressureexistiiig within the receptacle belonging to that nozzle may be varied by means of an adu'iitting screw. If the quantity of the liquid fuel supplied by the main nozzle becomes smaller, owing to clogging up or for other reasons, while the motor is running, or if the main nozzle fails entirely-to operate, the quantity of fuel suppliedby the auxiliary nozzle may beiincreased by opening the air admitting screw of the receptacle for this n'ozzle and letting'thus a higher pressure, for instance, atmospheric pressure act upon the fuel contained in this receptacle. In the latter case the auxiliary nozzle will operate, like the main nozzle, solely under the action of the partial vacuum existing in the suction pipe.
In order to make my invention clear, I refer to the accompanying drawings, in which:
Figure 1 is a vertical section through the carbureter on line AA of Fig. 4-. Fig. 2 1s a vertical section on line BB and Fig. 3 is a section on line CC of Fig. 4. Fig. 4: is a horizontal section on line D])' of Fig. l.
Specification o Letters Patent. P t t d y 19 19 4 Application filed July 8, 1913. Serial No. 777,895.
Referring to the figures of the drawing, a
is the main nozzle fed from the main recep tacle, b by means of a channel 0. in this receptacle islweighted by means of the weights 6 provided with suitable levers which are adapted to move downwardly with the float during the sinking of the level of the fuel and raim thereby the valve rod f for opening the fuel valve in order to replenish the fuel consumed. As soon as the level of the liquid has reached a predetermined height, for instance as shown, the float has been correspondingly raised and the-valve rod f has been lowered so as to close the valve and interru t the inflow-of the fuel. In the cover of the receptacle 5 an air vent g is provided. The fuel within the receptacle 6 therefore will be kept under atmospheric pressure. The fuel therefore will leave the spray nozzle a under a pressure equal to the preponderance of the atmospheric pressure over the pressure existing in the suction channel.
The auxiliary nozzle h is connected by means of a conduit 2' with the auxiliary receptacle k containing a float m and receiving its fuel supply through a channel Z from the main receptacle 6 (Fig. 3). The float m in the receptacle 7c is connected by means of a rod 25 to a valve o. controlling the fuel supfloat m, it will be clear that by suitable selections of this weight the height of the level of the fuel in the auxiliary receptacle 7.: can be kept lower than the level of the fuel in the main receptacle 6.
The air space in the receptacle/l; is connected through the channel a with the suction channel. The auxiliary receptacle .7: and the auxiliary nozzle it. therefore represent a system of communicating pipes standing under the suction or lower pressure.
' If the air nozzle .9 would not be provided properly regulating said screw atmospheric therefore be clear that only the current of .air issuing through the nozzle 8 will be the within the auxiliary nozzle h in the same Wider-the air inlet p is opened by the proper 1 tacle will be generated which is greater than that prevailing in the suction conduit.
it would be impossible to spray the" fuel through 'the auxiliary nozzle h. It will agent for causing an outflow of the fuel from the auxiliary nozzle it, because this air current will exert a suction upon the fuel manner as the blow tube of an inhaler of known construction acts upon the liquid container. The pressure prevailing in the auxiliary receptacle It will tend to produce a rise of the fuel within the auxiliary nozzle h, and thus materially facilitate the inhaling effect and increase the quantity of fuel exhausted through said nozzle. The
manipulation of the slide 0 the more will the surplus of pressure preponderate over the inhaling action for forcing the fuel through said nozzle and finally said inhaling action will be entirely overcome by the pressure and the nozzle will operate in the manner of an ordinary spray nozzle asfor instance the nozzle a. In order to permit the regulation of the fuel fed through the auxiliary nozzle a an air admitting screw 0 is provided at the upper part of the receptacle 70. By means of this screw 0 the width of the air inlet 79 can be regulated at will. If by air is allowed to enter the receptacle k, a constant increase-1n pressure 1n said recep- It is true that the part of the atmospheric air entering through the inlet p will flow off through the channel a however, as said channel is much smaller than the channel ,1) theloss of air led off through said channel is practically insignificant. If the auxiliary nozzle it has the same diameter as the main nozzle a, both nozzles will operate uniformly for spraying the same amount of fuel if the 1 air admitting screw 0 is manipulated so as i to fully open the air inlet 79. i
