T 0 all whom it may concern:
Be it known that I, EDWARD TERRY, a subject of the King of Great Britain, residing at Brixton, in the county of Surrey, England, have invented new and useful Improvements in Jet-Nozzles for Carbureters, of which the following is a specification.
This invention has reference to carburetors for internal combustion engines.
It has for its object to provide an improved jet nozzle for carbureters whereby a more efiicient explosive mixture may be obtained with a considerable saving of com bustible while at the same time obviating the accumulation of soot on the valves and sparking plugs.
In its broadest aspect the invention contemplates a jet nozzle for the carburetors of internal combustion engines in which the liquid combustible is caused to impinge upon a gauze so mounted directly in the path of the jet that a predetermined amount of combustible only shall be volatilized in passing through said gauze at each induc tion stroke of the engine.
More specifically considered the invention comprises a jet nozzle for the carburetors of internal combustion engines having a gauze supported directly in the path of the jet of liquid combustible means whereby the relative position of said gauze with respect to the orifice of the jet nozzle may be varied in accordance with requirements and means whereby any unvolatilized combustible may be led to tank or receptacle.
In order that my invention may be readily understood and carried into effect by those skilled in the art to which it appertains I will now proceed to describe the same fully for which purpose reference is to be had to the accompanying drawings in which:
Figure 1 represents a verticalsection of a jet nozzle for internal combustion engines embodying this invention. Fig. 2 is a top plan view thereof. 7
In the embodiment of the invention illus trated the jet nozzle a threaded as at b to adapt it for connection to a carbureter (not shown) is provided with a cup or receptacle 0 having an orifice d formed in the base thereof for a purpose which will be presently explained. Secured to said cup 0 are two vertical rods 6 serving to support an adjustable thimble f in the center of which is an orifice g covered with fine mesh wire gauze h. In the drawing the thimble f is shown as being provided with holes 2' through which the rods 6 pass, appropriate set screws j being provided for securing the thimble in the desired position.
The operation of my improved carbureter jet nozzle is as follows: Upon each induction stroke of the piston a quantity of liquid combustible is sucked through the nozzle (1 from the float chamber or other receptacle for the supply of the fuel and projected through the restricted orifice 7: directly onto the gauze h. A portion only however of the liquid fuel passes through the gauze k and orifice g in the thimble f when it is immediately volatilized and mixing with the air supplied to the carbureter passes directly into the induction pipe and thence to the combustion chamber of the cylinder in a gaseous condition. That portion of the combustible which is unvolatilized falls into the cup 0 flows through the orifice (Z in the base thereof to a suitable receptacle for reuse or I may provide a pump to return it directly to the float chamber.
A carbureter jet-nozzle in accordance with this invention possesses many advantages over devices of the kind as heretofore constructed for it will be apparent that by means of my improved device only sufficient liquid fuel is volatilized at each induction stroke as is required to form the correct explosive mixture the surplus being recovered for re-use instead of being sucked into the combustion chamber as is often the case with carbureters as heretofore constructed thus preventing the formation and deposit of soot upon the valves and sparking plugs.
I claim:
1. A jet nozzle for carbureters comprising the combination with an ejector supply pipe for the liquid combustible, a cup surrounding portion of said pipe and having a discharge orifice therein, supports carried by said cup and a gauze supporting member adjustably secured to said supports.
2. A jet nozzle for carburetors comprising the combination with an ejector supply pipe for the liquid combustible, a cup surrounding a portion of said pipe and having a discharge orifice therein, supports carried by said cup and an inverted thimble having a gauze covered aperture therein adjustably secured to said supports.
3. A jet nozzle for carbureters comprising the combination with an ejector supply means for retaining said thimble in any depipe for the liquid combustible, a cup sursired position upon said supports.
rounding a portion of said pipe and having a discharge orifice therein, supports car- EDWARD TERRY 5 ried by said cup and an inverted thimble having a gauze covered aperture therein adjustably mounted on said supports and Witnesses:
