V H E C H T CARBURETOR VALVE ASSEMBLY Sept. 18, 1962 v Filed Aug. 15, 1960' FIG. 2
FIG.
INVENTOR. VIC TOR H E CH T W 3,054,594 CARBURETOR VALVE ASSEMBLY Victor Hecht, 969 Alexander, Haysville, Kans. Filed Aug. 15, 1960, Ser. No. 49,595 4 Claims. (Cl. 251-333) This invention relates to carburetors, and in a more specific aspect to means for positively controlling fuel intake into the carburetor bowl to prevent flooding and increase the eflicient use of the fuel.
Heretofore various types of carburetor constructions have been known to the prior art. These constructions include valve means controlling the fuel intake into the carburetor in relation to the amount of fuel in the carburetor bowl. The prior art devices have not proved eflective in operation in positively sealing the fuel inlet when the fuel in the carburetor bowl is at the desired fuel level, resulting in flooding and excessive use of fuel.
In accordance with the present invention an improved carburetor construction has been provided which overcomes the deficiencies of the prior art. The carburetor includes valve means in the fuel inlet which function with the fuel level in the bowl so as to open or positively close the inlet into the carburetor, thereby preventing excessive use of fuel and overcoming flooding problems existing in the prior art devices.
The preferred carburetor construction includes a carburetor bowl having a fuel inlet and outlet. A valve is mounted in the fuel inlet to positively control the amount of fuel received within the carburetor bowl. The preferred valve construction includes an O-ring positioned within the hollow of the valve body which is engaged by the valve operator to positively close the valve and control the amount of fuel received within the carburetor bowl. The valve operator is preferably operated by the carburetor float in response to the fuel lever in the carburetor bowl.
Accordingly, it is an object of this invention to provide a new carburetor construction.
Another object of the invention is to provide a new carburetor construction incorporating valve means therein to positively control the fuel intake and prevent flooding and excessive use of fuel.
A still further object of the invention is to provide a new carburetor construction having an improved valve means mounted in the fuel intake to the carburetor bowl.
Another object of the invention is to provide a new carburetor valve.
A still further object of the invention is to provide a new carburetor valve having sealing means therein engageable by the valve operator to positively control the flow of fuel into the carburetor bowl.
Another object is to provide an improved carburetor valve which is inexpensive to construct and easy to assemble.
Various other objects, advantages and features of the invention will become apparent from the following description taken in connection with the accompanying drawings, in which:
FIG. 1 is a cross section view showing the preferred construction of the carburetor of the invention with the new valve means mounted in the fuel inlet.
FIG. 2 is an enlarged cross section view through the improved valve means.
Patent FIG. 3 is an enlarged cross section view showing the O-ring retainer with the O-ring mounted therein.
FIG. 4 is an enlarged iso-metric view of the valve operator used in the carburetor valve of the invention.
The following is a discussion and description of a preferred specific embodiment of the new carburetor and carburetor valve of the invention, such being made with reference to the drawings whereon the same reference numerals are used to indicate the same or similar parts and/ or structure. It is to be understood that such discussion and description is not to unduly limit the scope of the invention.
Referring now to the drawings in detail, FIG. 1 shows a carburetor bowl 10 having a top .12. Top 12 has a fuel inlet 14 and the fuel line to the carburetor can be secured to the threaded end 16 of the fuel inlet 14. A carburetor valve, shown generally at 18, is mounted in fuel inlet 14 to control the amount of fuel received within the carburetor bowl 1G. Suitable fuel outlets (not shown) convey the fuel in the carburetor bowl 10 to a gasoline engine or the like.
A float 20 is pivo-tally mounted at 22 to the side of the carburetor bowl 10 in any suitable manner and is raised and lowered as the fuel 24 fills the carburetor bowl 10. The arm 21 on the carburetor bowl serves to open and close the valve 18 in the manner hereinafter explained.
The valve 18 includes a valve body 26 which is reduced in diameter and threaded at one end portion as shown at 28. The threaded end 28 is threadedly mounted in the fuel inlet 14 on top 12 and projects inwardly into the carburetor bowl. The valve body 26 is hollow and preferably has a shoulder 30 formed therein.
Suitable sealing means are preferably received within the hollow of the valve body 26. A preferred manner of providing the sealing means is shown in FIGS. 2 and 3 and includes a generally annular O-ring retainer 32 which has a bottom 34 and a side 36. The retainer 32 has an opening 38 through the center thereof and is preferably split as shown at 40 from the center opening 38 across the bottom 34 and up the side 36. The provision of the split 40 permits the retainer 32 to be compressed when mounted.
The side 36 of the retainer 32 is preferably tapered inwardly from the bottom 34 as illustrated in FIG. 3. Preferably the side 36 is tapered at approximately a 3 degree angle, the tapering being provided so that when the retainer is received within the hollow of the valve body 26 as shown in FIG. 2 the edge between the side 36 and the bottom 34 will bite into the hollow of the valve body to secure the retainer therein. Other means can be used to retain the sealing member within the valve body 26, such as by providing snap rings or the like to contact the valve body, however the retainer shown and described has been found to be very satisfactory and inexpensive to construct.
An O-ring 42 formed of a suitable resilient material is provided and is received within the O-ring retainer 32. The O-ring 42 is desirably dimensioned relative to the retainer 32 so as to project slightly above the side 36 and into the hollow or opening 38. When in position in the valve body 26, the O-ring 42 will thus engage the shoulder 30 formed therein and be in sealing contact therewith. The O-ring 42 can be formed of various types of plastics, rubber materials, synthetic rubbers and the like. O-rings sold under the trademark Biton by the Parker O-ring Company of Cincinnati, Ohio, have been found desirable in this application. The O-ring used should be one which will remain flexible over a wide range of temperatures and will not be attacked by the fuel being used.
An elongated valve operator 44 is provided. Operator 44 can be rectangular in cross section in the body portion thereof and preferably has a tapered conical end portion 46 as shown in FIG. 4. The valve operator 44 is dimensioned relative to the hollow opening in the valve body 26 so as to be received therein and to provide space for the passage of fluid or fuel therethrough. The coni cal end portion 46 of valve operator 44 is receivable in the opening 38 of the O-ring retainer 32 and will engage the O-ring 42, urging it into sealing engagement with the shoulder 3t) in the valve body 26. The operator 44 is urged into engagement with the O-ring by the arm 21 of the float 20 when the fuel 24 is at the full level in the carburetor bowl 10. As fuel is withdrawn from the carburetor bowl 10, the float 20 will be lowered with the fuel level and the arm 21 will be released from engagement with the valve operator 44. The tapered end portion 46 of the valve operator will thus be released from sealing engagement with the O-ring 42, thereby permitting entrance of fuel into the carburetor bowl through the fuel inlet 14 and the valve 18 as shown by the arrows in FIG. 1. When the carburetor bowl is again filled to the full level with fuel, the arm 21 will engage and urge the valve operator 44 into the valve body 26 and into sealing engagement with the O-ring 32 to positively and effectively seal the fuel inlet. This positive control of fuel intake eliminates flooding and excessive use of fuel in the carburetor.
The carburetor and valve means shown and described hereinbefore is extremely simple to manufacture and install. The valve means consists of a minimum number of parts, requiring no special fitting or machining. The valve means can be installed in present day carburetors merely by removing the standard valve and threadily mounting the valve body 26 in the fuel inlet. The positive opening and closing of the fuel intake into the carburetor bowl results in substantial savings in the fuel consumed and eliminates flooding experienced with the prior art devices. The carburetor valve, with the exception of the O-ring, is preferably made of brass to avoid rusting.
While the invention has been described in connection with a preferred specific embodiment thereof, it will be evident that this description is intended to illustrate and not limit the scope of the invention, which is defined by the claims.
