LAWRENCE R. GRAMES, OF WELLSVILLE, NEW YORK, ASSIGNOR F ONE-HALF TO JOHN N. BRYSON AND R. R. MURRAY, 0F WELLSVILLE, NE'VV YORK.
ENGINE VALVE.
Application filed October 13, 1926. Serial No. 141,362.
This invention relates to a valve for controlling admission of air and fuel such as gasoline to internal combustion engines, one of the objects being to provide a novel form of valve under the control of a remote operating means which, when actuated, will open or close a novel arrangement of ports Where by proper proportions of air and gasoline within the scope of what is claimed, without departing from the spirit of the invention.
In the accompanying drawings, the preferred form of the invention has been shown.
In said drawings,
Figure 1 is a section through the valve.
Figure 2 is an elevation thereof.
Referring to the figures by characters of reference 1 designates the valve casing provided with an outlet 2 through which fuel is directed to the engine. This casing 1 has an open side 3 to which is bolted or otheran wise connected a cover plate 4 provided with an annular series of air inlet ports 5 and also provided with a pin 6 extending inwardly from the cover.
An additional port 7 is formed in the cover and is in communication with a threaded recess 8 to which a. fuel supply pipe, not shown, is to be connected.
Mounted for rotation within one wall of the casing 1 and in the cover plate 1 is a shaft 9 to one end portion of which is secured a radial arm 10 adapted to be connected to a governor rod or throttle control not shown. Secured to this shaft 9 at a point within the casing 1 is a collar 11 and 4 mounted for rotation and sliding movement on the shaft is a dished valve 12 having an ports 5 and 7 and the marginal portion 15 of valve 12 serves normally to close these ports because spring 14 presses the parts together. An arcuate slot18 is formed within the valve member 16 andflreceives pin 6,
thereby to limit the rotation of the valv'e member 16 relative to the cover 4..
lVhen the parts are in one position fuel is free to enter the opening 17 in commun1- cation with port 7 and air is free to enter the other opening 17 by Way of the ports or apertures 5. By rotating shaft 9 the valve member 16 can be rotated within the limits allowed by slot 18 and pin 6 so as to partly or entirely close the apertures 17. Each suction stroke of the engine will cause the valve member 12 to move against the action of spring l l so that air and fuel will be sucked into thee-using 1, the amount being dependent upon the position of the valve member 16. If desired V-shaped grooves,
7 indicated by dotted lines at 19 can be formed in the Walls of the openings 17 so as to give a more gradual opening of the ports than would otherwise occur.
lVhat is claimed is:
The combination with a casing having an outlet and an open side spaced therefrom, of a cover plate for closing the open side, a shaft journaled therein and in the casing, means for rotating the shaft, there being an annular series of apertures in the cover plate, said series being concentric. with the shaft, said plate having a fuel port opening therethrough, a valve disk rotatable with the shaft having an annular series of apertures movable into and out of register with the air and fuel ports in the cover plate, cooperating means upon the cover plate and disk for limiting the back and forth rotation of the disk relative to the cover plate, a slidable valve on the shaft having its marginal portion normally bearing against and closing the apertures in the dislgand yielding means carried by the shaft and engaging the slidable valve for holding said valve pressed normally against the disk, said slidable valve being shiftable by suction through the registering apertures in the disk and cover plate to admit fuel to the casing when the valve is subjected to suction from the outlet of the casing.
In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
