UNITED STATES WILLIAM E. KENT, OF LOS ANGELES, GALIFOBNIA..
AUXILIARY AIR-INLET VALVE FOR CARBURETORS.
Application filed August 22, 1921.
To all whom it may concern:
Be it known that 1, WILLIAM E. KENT, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful improvements in Auxiliary Airlnlet Valves for Carburetors, of which the following is a specification.
This invention relates to auxiliary air inlet valves for carburetors and has for its object to provide novel means whereby the volume of air drawn into the carburetor by the suction of the engine will be proportionally increased with the increased suction produced by the engine.
The invention will be readily understood from the following description of the accompanying drawings in which:
Fig. 1 is a side elevational view showing a carburetor and manifold with the air inlet valve broken away and shown in section.
Fig. 2 is a perspective of the valve cylinder.
The usual manifold 1 is shown leading from a carburetor 2 and having an auxiliary inlet casing 3. A valve cylinder 1 is positioned within the casing 3 and shown as having a radial flange 5 adapted to engage the upper edge of the casing 3. The wall of the cylinder has tapering openings 6 formed by the tapering portions 7. The openings 6 terminate below the flange 5 leaving a central opening 8 in the top of the cylinder 4 which has communication with an annular chamber 9 through the openings 6, the chamber 9 communicating with the manifold 1.
A piston 10 is yieldably slidably mounted within the cylinder and has 2, depending guide rod 11 slidably mounted in an adjusting nut 12 which has screw threaded engagement with the bottom portion of the casing 3. A coiled spring 13 surrounds the guide rod 11 and yieldably forces the piston upwardly. Stops 14 are provided within the cylinder to limit the upward movement of the piston.
In the operation the engine will create a suction in the chamber 9 which will cause the piston to be drawn downward against the tension of the spring 13 until enough of the passages 6 have been opened to allow a sufficient quantity of air to pass through the same. Increased suction will cause proportionally increased opening due to the tapering of the same. The tension of the Serial No. 494,341.
spring can be regulated by the adjusting nut so as to cause the piston to allow the proper opening for a given suction.
The valve cylinder 4 may be held in position by a nut 15 having threaded engagement with the casing 8 and having a flange portion 16 over lapping the flange 5 of the cylinder, there being a central opening 17 in axial alinement with the opening 8.
Various changes in the details of con struction of my invention may be made by those skilled in the art without departing from the spirit of the invention as set forth in the appended claims.
What is claimed is:
1. The combination with a carburetor, of an air inlet valve comprising a cylinder, tapering openings in the wall of said cylinder, a piston in said cylinder, a guide rod extending from said piston, an adjusting nut adapted to slidably receive said rod, a spring on said rod, and means for limiting movement of said piston in one direction.
2.1n combination, a casing, a cylinder arranged concentrically within the casing and having its wall provided at intervals with openings which taper toward the upper end of the cylinder, a radial flange formed on the upper end of the cylinder, and a threaded and flanged member engaging the upper end of the casing for securing the flange to. the casing, a piston movable within the cylinder, a rod slidably mounted in the bottom of the casing, an adjusting nut mounted in the bottom of the casing and slidably receiving said rod, an expansible spring surrounding the rod between the nut and piston, and stops formed on the inner wall of the cylinder for limiting the upward movement of the piston within the cylinder.
3. In combination, a casing, a cylinder within the casing, releasable means for rigidly securing the cylinder within the casing, said cylinder being formed with portions which taper in width toward their lower ends, a piston slidable in the cylinder, stops formed in the cylinder for limiting the upward movement of the piston, a rod connected with the piston and slidable through the bottom of the casing, an adjusting nut threaded into the bottom of the casing and slidably receiving the rod, and a spring interposed between the nut and piston for normally urging the latter upwardly toward said stops.
