Application filed May 5, 1924.' Serial No. 711,029.
This invention relates to Vaporizers intended to be used in conjunction with internal combustion engines of the externally vaporized fuel type.
The object of this invention is to provide a vaporizer in which a portion of the air and all the fuel is heated and the remaining por 7 tion of the air is unheated, whereby the fuel may be thoroughly vaporized without unduly 10 raising the mean mixture temperature after the two portions of air are reunited.
Figure 1 shows a cross sectional elevation on the plane 11 of Figure 2.
Figure 2 shows a partial elevation on the plane 22 of Figure 1.
In the drawings, A is a constant level fuel supply chamber having a cover B provided with a depending sleeve C and supporting a needle valve D, which controls the'fuel outletE in the fuel nozzle F. The fuel nozzle F projects above the level XY of the fuel in the constant level fuel supply chamber A, being concentric with and located within the dependent sleeve C. An air vent G is provided for the upper portion of the sleeve C. The cover B is also vented to theatmosphere so that atmospheric pressure exists at all times within the float chamber A. These details are copied from the co-pending application of George R. Welch, Serial No.
709,322, filed April 28th, 1924.
The lower portion of the fuel nozzle F is shown discharging in the throat of the venturi H. The air necessary for the mixture which is located a swinging air valve. A throttle valve K in the. mixture outlet controls the flow of fuel. L is the fuel vaporizing chamber communicating with the inlet manifold M through the opening N. The heating pot L projects into the exhaust manifold O." A diaphragm P is located within the heating pot L, the upper portion of which contacts with the throttle rod K and is so arranged that the operation of the throttle rod K permits half the air and all the fuel from the nozzle F to be heated in the pot L. Meanwhile the unheated air flows to the left of the throttle rod K, in Figure 1, and oes directly through N into -.-the manifold Q is a small hole in the throttle located on the nozzle side of the mixture chamber to facilitate the flow of fuel through the heating pot during idling. Risa drain hole to haust thereby admitted will have no deleis supplied through the air entrance J .m
revent any fuel accumulating in the heatmg pot at any time. The fact that this hole communicates directly with the exhaust is not objectionable, as the small amount of exterious effect. I
0pemtion.-During the operation of the engine, whether the throttle K is opened or closed, the fuel nozzle F discharging to the right of the throttle valve K, in Figure 1, al-
7 ways discharges into the heating pot L. B
this means all the fuel and half the air s always subjected to the full heatingeifect of the exhaust gases escaping from the manifold O. Q 7
Owing to the fact that the path through the heating pot is longer than the short cut to the inlet manifold taken by the pure air, approximately one half the air passes into the inlet manifold unheated, which is an advantage.
What we claim is: V
1. A vaporizer comprising a mixing chamber, a fuel nozzle discharging therein, a mix- 'ture outlet, :1. throttle valve therein, said throttle valve being adapted to separate the air into two equal parts and to direct the fuel into one half, two conduits leading from said mixture outlet into which said equal portions of the air are directed, means for heating that conduit into which the fuel is directed by said throttle valve, means for reuniting the two air streams into a common outlet.
2. A vaporizer comprising a mixture chamber, a fuel nozzle discharging therein, a mixture outlet, a throttle valve therein, a fuel vaporizing chamber connected with said mixture outlet, a partition therein co-operating with the throttle .valve so as to form two passages on opposite sides of said throttle and toform a U-shaped passage within said chamber forming one of said passages, means for reuniting the two passages into a common outlet, said throttle being adapted to divertall the fuel and half of the air thron glh said vaporizing chamber andto divert e remaining portion of the air to the said common outlet, and means for heating the outside only of said vaporizing chamber.
3. A vaporizer comprising a mixture chamber, a fuel nozzle discharging therein, a mixture outlet, a throttle valve therein, a dependent vaporizing chamber connected to said outlet, a partition co-operating with the throttle valve sons to form two common outlet, and means for heating the passages on opposite sides of said throttle, outside onlyvof said U-shaped vaporizing means for reuniting the two" passages into chamber. 7 1 a common outlet, said throttle valve being In testimony whereof we .afiix our signa- 5 adapted to divert all the fuel and half the tures.
air through said vaporizing chamber and to RAYMOND M. ANDERSON. divert the rest of the air unheated to the STANLEY
