UNITED STATES PATENT OFFICE.
CARBURETOR FOR INTERNAL-COMBUSTION ENGINES.
Application led January 19, 1925, Serial No. 3,423, and in Great Britain January 2a, 1924.
This invention relates to carbureting apparatus and vaporizers, for internal combustion vengines of all types, and it has for its objects to impart a greater' velocity to the fuel jet, and a quicker and more thorough vaporization to the fuel issuing from the jet, the said apparatus preventing ooding and being thus rendered efficient at any altitude.
According to the invention the said apparatus is provided with a hand operated tapered cock inserted in the base thereof and provided with two passages controlling respectively the admission of liquid fuel and air, or gas, under pressure whether hot or cold,- to a common nozzle for .the purpose of imparting a greater velocity to the fuel jet, andalso for giving a quicker and a more thorough vaporization of the fuel issuing from the jet. n 20' I am aware that a carburetor has been proposed in which fuel and air under pressure are supplied toa common nozzle under the control of a single suction-actuated valve.
And in order thatthe invention may be readily understood, I will now describe it fully with reference to the accompanying drawings, wherein:
Fig, 1 is a longitudinal section of so much of the improved carburetor as is necessary to show its construction.
Fig. 2 is a transverse section of the same taken on the line w-x of Fig. 1, and showing clearly the relationship between the entrance for the fuel and the air, or gas, under pressure.
Fig. 3 is a detached view, partly in section, of the tapered cock for controlling both the fuel and the air, or gas, under pressure, these being arranged to work together or in unison.
In these drawings a is the carburetor cas` In carryingout the invention, the base piece y of the carburetor is provided with va horizontal conical passage y1 in which there is arranged a hand-operated tapered cock g provided with two passages adapted to control respectively the fuel and the air, or gas, under pressure, the passage g1 being that for the fuel supply and 'g2 that for the supply of the air, or gas, under pressure.
The different relative positions of the fuel supply g1 and the air, or gas, under pressure supply g2, are clearly shown in Fig. 2 as is also the vertical passage h2, leading from the air, or gas, under pressure supplypipe hereinafter referred to.,
Extending across the base y, and at right angles to the conical passage y1is the inlet it leading from any external source of air, or gas, under pressure; the unwanted length of said passage being Vplugged by a screw h1, or other suitable means.
h2 is the aforesaid'vertical entrance from the inlet L in the base piece 'y with which also connects the air-pipe k3.
j is the inlet pipe through Which the hot gases pass into and through the usual conical hot-plate jl and which diffuser is arranged within the connection tothe engine. j2 is a subsidiary pipe leading from the diffuser to ajacket js, arranged around the fuel supply pipe e, for the purpose of warming said pipe, when desired. and ljt-are perforations in said jacket to allow of the escape of gas. It is to be understood that the conical dit'- fuser, or atomizer-vaporizer, jl, intercepts and atomizes any jet, spray, or other injec-` tion of liquid fuel. K
In operation, the air or gas, under pressure may be either compressed air or other gas, such as oxygen, o-r a mixture of both, and either hot or cold; the usual regulating valve being provided when a. mixture is desired.
I claim A carbureting apparatus or vaporizer, comprising a tapered cock, two conduits respectively for the admission of liquid fuel and air or gas under pressure and a nozzle common to both conduits; the said tapered cock serving to control both conduits.
JOI-IN THOMAS.
