PATENT OFFICE. l

GAS-ENGINE.

To all lwhom t may concern Be it known thatI, CHARLES P. 'SKUBLIN, a citizen of Russia, residing 'at Detroit, county ofWayne, CState ofy Michifan, have invented a 'certainnew and useful ymprovenient in Gasdngines, and declare'thefollowingto be a full, clear, and exact description of the saine, such as will enable others skilled inthe art to Ywhich it pertains to make and luse the same', reference being had to the accompanying drawings, which form 'A Va partV of this specification.

VMy invention relates to an improvement `in internal combustion engines, shown in theV accompanying drawings and more particularly pointed out in the following specification and claims.

This invention is designed as animprovel ment on that' shown and described in United States Letters Patent No. 1250683, issued to me December 17, 1917. s

One ofthe objects of the present invention is to provide a single rotary valve adapted to control both the inlet and exhaust ports of the several cylinders of an engine.

Another object ofthe invention is to coni struct the valve. with an annular passage v through which the combustible mixturemay operate tofiiood the cylinders ,with oil. 4

Another feature of the invention is lthe means `provided for `draining back all' surplus'oil to the crank-case. l

With the foregoing and othery objects in view, which will appear as the description proceeds, the Vinvention resides," in) the combination andi arrangement of parts and in the details of construction hereinafter described and claimed, it being understood Vparting from the spirit 0f the invention. f i

that changes maybe made in the precise Specification of Letterslatent. Patented Tunas-V29, .1920;V I Appli-cation filed November 151918.` serpiaiiwo. 262,661." 'i l' embodiment herein disclosed without .,de- "i In, the accompanying drawingsel- Figure l is a longitudinal horizontal sectional view through the engine and valve I chamber.

`F 2 is an end elevation ofthe/engineshowing the crank shaft connection `foroperating the valve. y

F ig.` Sis a vertical cross-'sectional view `on line 3 3 of'F'ig. l, showing partsinelevation, the valve being positioned as it]` would l appear on thefsuction stroke. I i

Fig. 4 is a similarview with thev valve positioned as on the compression stroke.

Fig. 5 is a likesectional view with the* valve positioned as when the explosion'occurs.

" i... Fig. 6 is a fragmentary longitudinalsvertical sectional view through the valve, l'showing the oil duct, oil inlet and discharge pipe connections, and oil overflow pipe.

Fig. 7 is a diagrammatic-view indicating a single rotation of the valve and lits "chronological order ofv operation.'

Y Referring now to the letters of reference plzltped upon the drawingsfits cylinders and C, their water jackets.

denotes the crank case of the engine, Il?,

a designates a crank-shaft journaled in the crank-case'. 15, are pistons, and F, are rods connecting the pistons with the crankeshaft.

G, is a longitudinal tapering valvesupported in a valve' chamberG1 connected by suitable ports in the valve chamber with the respective cylinders inclosed by a lwater jacket C1 communicatinglwith the water jacket C of the cylinders. -1

Intermediate of the' ends of the valve chamber is an intake connection H,`to which i agcarbureter I may be attached as shown in Fig. 2 of Vthe drawings.`

Extending. longitudinally within thek valve is an exhaust passage jg for two`of the engine cylinders, divided by a longitudinallyv extending cross partition g1,- forming `anexhaust passage gzffOT the Othel" cylin'y `for the deliveryof the exhaust ygases into the chamber G2, from Which they are discharged through the opening G3.

g3 are radial ports adapted to successively communicate With the cylinder ports B1, 'through which .theV combustible mixture is delivered to the cylinder, and kt'heexhaust gases discharged therefrom.

' ga is an annular longitudinal passage in the valve having an intermediate peripheral 4channel-gb forcomlnunication With the carbureter I, and vvithrlradial ports g?, for the delivery of the Vcombustible mixture to` Athe ports B1, leading to the respective cylinders. t l

vL, ,denotes a non-heat conducting insulation between the Walls of the annular passage g@ through the valve and its centralex- .haust passage g; that the valve may not expand and bind in its chamber through the heat produced by the lexhaust gases passing rotation of `the valve.

therethrough. f:

M, is a longitudinal Well .or ductl extendingthe length Aof the valve having one'of its side YWalls 1M? inclined in 4the direction of the -Gr-4 the intermediate Wall G5 (closing the peripheral gas inlet channel gb from the oilduct M) and passes back to the crankcase through thepipe N1. f

P, designates a suitable oil pump actuatedy from the crank-shaft for delivering oil lto the duct M, Q, denotesan auxiliary overvalve chamber,

4flow pipe for conducting any surplus oil back to the crank-case, thus relieving any lpressure caused by the action of the pump,

and thereby providing` against the cylinders becoming flooded With oil.

R, is a Worm gear keyed to the valve stern G2, actuated by a suitable driving connection S, in turn operated by the engine crankshaft. T., denotes a spring sleeved on the valve stem and bearing against the end -Wall ofthe valve chamber and against the .gear R, to maintain the valve in an intimate contact relationship with the Wall of the U, designates the spar-k plugs of the reispective cylinders.

It Will now be understood ,that the rotation of the valve is relatively slo\v,-asthe several operations of the respective cylinders k.ln-iovvnas suction compression explo- 7 sion and exhaust are served upon each "revolution of the valvei-.the Wear ,of parts is thus materially decreased.

The longitudinal oil duct is of suicient prQYded with an inclined Wall on At each end ofthev one side in order that any surplus oil that may have entered 'the vradial ports inthe valve can drain back into the `oil ductas the valve rotates into juxtaposition with the Wall of the valve chamberfollovving the passage of'said' oil duct.l f

. By providing the valve With inlet and exhaust passages adapted to control the delivery of the combustible mixture and the discharge of it's burnt gases through the same .ports of the respective cylinders,' the cost of'manufacture has been reduced and the simplicity of its'operation has been materially increased. So also by providing-va non-heat conducting insulation between the inlet Vandthe yexhaust passages through the valve, the expansionl of the valve and consequent binding chamber has been overcome. l y Having' thus describedmy invention, What I claim is:A i Y A 1. The combination With aninternal combustion engine comprising a plurality of cylinders, a tapering valve ,chamber having channels leading to all `of the cylinders, a tapering rotary valve in said valve chamber having an ,annular "longitudinal channel with ports adapted to i successively register with the channelsleadi'ng to .the respective cylinders for delivery of ,an explosive mixture thereto, the tapering valvejbeng Vprovided vvith a tapering central longitudinal passage having aA division plateV extending for a portion of its length to form compartments in said tcentral passage', radial ports in both .compartments of said central passage adapted to be brought into registration of the same in.' the `Vvalve with the channels `connected with the .cylinders for discharge of the burnt gases therefrom, and means actuated by the crank- ,shaftvof the ,engine for rotating said valve.
