T 0 all w hom t 'may concern:

Be it known that l, HARvEY J. SALLEE, a citizen of the United States, and a resident of Whitehouse, Shasta county, State of California, have invented a certain new and useful Improvement in Internal-Combustion Engines, of which the following is a speciiication.

The invention relates to internal combustion engines and particularly to a rotary distributer valve for convfving thef explosive mixture and the products of combustion.

An object of the invention is to provide means for cooling the valve.

Another object of the invention is to provide a valve which may be cooled with either air or water or both.

A further object of the invention is to )rovide means for the passage of a cooling uid between the intake gas passage and the exhaust gas passage.

A further object of the invention is to provide means for lubricating the entire surface of the distributer valve.

The invention possesses other advantageous features, some of which, with the foregoing, will be set forth at length in the following description where I shall outline in full that form of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. In said drawings l have shown several embodiments of my invention but it is to be understoodthat l do not limit myself to such forms, since the invention, as expressed in -tlie claims, may be embodied in a plurality of forms.

Referring to said drawings: y

. My invention relates to a rotary distributer valve for multicylinder engines, which serves as a conduit for the explosive mixture and the exhaust gases .and which functions by its rotation. to open the passages within the valve to the cylinders at the proper time. In accordance with my invention, I provide a rotary distributor valve in which a cooling fluid flows between the inlet and exhaust conduits which lowers the temperature of the exhaust conduit and checks or retards the transfer of heat to the intake conduit. -l

valso provide means for properly lubricating .the entire surface of the valve, and this in combination with the cooling elfect produces an etlicient operating structure.

The rotary distributor valve of my invention is particularly adapted for use in multicylinder engines and is preferably disposed in a cylindrical seat 12 formed directly over the cylinders 13, the wall between each cylinder and the valve seat 12 being provided with a port 14 for the passage of the explosive mixture and the gases of combustion. The distributer valve 15 is rotated in time with the crank shaft of the engine through the medium of the gear 1G secured thereto and the chain 17 engaging said gear and a gear of the proper size on the crank shaft.

The distributer valve is formed of a plurality of concentric tubes or conduits through which the various gaseous mixtures pass and the tubes are provided with ports opening on the face of the valve and in position to register at the proper time with the ports 14. The gaseous mixture conveying tubes are spaced apart radially forming passages between them for a cooling iuid or fluids. rl`he distributer valve shown in Figs. 2, 3, il, 5 and 6 comprises an outer or bearing tube 18 which forms the outer wall of the explosive mixture passage into which the explosive mixture is introduced from the conduit 20 through the rows of circumferential ports 19 disposed adjacentthe ends of the tube 18. This tube is provided with a plurality of properly disposed ports 21 through which he explosive mixture passes into the cyliners.

Arranged within and concentric with respect to the louter tube is an inner tube 22 for the exhaust gases, and at each cylinder, the tube 22 is provided with a port 23 extending to the Surface of the valve and provided on the sides with walls 24 to separate it from the other passages within the valve. Arranged intermediate the tubes 18 and 22 are tubes 25 and 26 which form passages for the cooling fluid, the tube 25 forming the inner wall of the explosive mixture passage. This tube is'flanged at its ends and is joined to the outer tube at the sides of the apertures 19 adjacent the ends of the tube, thereby separating the explosive mixture passage from the cooling fluid passages. The tubes 25 and 26 arev also flanged and secured to the outer vand inner tubes adjacent the exhaust ports 23 so that chambers 27 for the cooling fluid are formed immediately behind the walls 24, and this keeps the walls 24 coolfand reduces the temperature of the exhaust ases before they enter the tube 22. The tues 25 and 26 are open on their ends and the tube 18 is open' at its forward end to permit'the free 'flow of the cooling fluid therethrough. rlhe cooling fluid may be air or water, and inthe construction shown in llig. 2, l prefer to use air which enters the valve through the open4 forward end of the tube 18. When the engine is used on motor vehicles, the speed of the vehicle forces air into the tube and this action is increased by a tan 31 arranged inthe forward end of the tube. rlhe air, after passing through the tube, discharges through the-apertures 29 in the outer tube 18 which register with apertures 28 formed inthe seat 12. By forming two separate longitudinal passages for the coolin fluid, the hot duid produced by contact with the exhaust tube 22 is prevented from vcoming into direct contact with 'the tube 25 and thereby the tube 25 is kept cooler than it only one duid passage were employed.

Means are provided for edectively lubricating the bearing surface of the valve. Extending down through the head 32 of the engine, which is -tornied as a water jacket 'for the bearing cylinder l2 are a plurality of oil conduits 33 connected to the distributing, pipe 34. The outer surface of the tube i8 is provided inline with each conduit 33 with a circumferential oil groove 35 and the excess oil is drained off through the tubes 36 communicating with the valve seat at the bottom and openinginto the grooves. The grooves 35 are preierably arranged between the cylinders. lin order to insure the lubrication of the valve and seat between the grooves. l have provided a bridge 37 in if. inlet port 21, the face of the bridge g flush with the face oi2 the tube 18.

ing the entire Valve surface between the circumferential grooves. The two arms of the bridge are inclined ybackwardly in respect to the direction of rotation of the valve, to the center of the port and are there jboined by a circumferentially disposed ridge arm 39 forming a Y-shaped bridge over the port. rilhe arm v39 is provided with a groove 41 which joins the grooves 38 and the groove 41 opens on the sides of the arm 39 and into the intake manifold, so that the oil in the groove is subjected at alltimes to the vacuum existing in the intake manifold. This causes a positive flow of the oil in the groove and prevents the oil from carbonizing and collecting in the grooves and choking them. The impeller force of the in! clined grooves in combination with the continual pull of the vacuum causes the oil to flow freely through the grooves.

The construction shown in Fig. 7 is designed for use with two cooling fluids, such as air and water. The tube 25 is flanged on its ends and joined to the outer tube 18 as in the prior construction. rl`he tube I26 is also danged on its ends and is joined to the outer tube 18 at oints beyond the points of attachment o the tube 25, thereby forming two separate cooling fluid passages. Water is admitted to the outer passage through the apertures 42 in the outer tube, passes longi* tudinally through the valve and discharges through the apertures 43 at the other end. Studing boxes 44 and 45 arranged adjacent the apertures 42 and 43 prevent water leakage at these points. Air is admitted through the forward end ot the outer tube and driven ,ploy-the tan 31 passes longitudinally through the passage immediately surrounding the exhaust manifold 22 and is discharged through the apertures 46 at the other end of lthe valve. j

lin the structure shown in Fig. 8, only one tube 25 is arrangedbetween the-outer tube 18 and the exhaust maniiold 22 and air or water may be dowed through the passage formed between the tubes 22 and 25; This c cooling duid is introduced into and moved through the passage in the sanie manner as previously set forth.

lin the construction shown in Figs. 9 and i0, only one cooling duid is used, which may .be air or water, and the duid is introduced into and `discharges from 'the valve at the same end, passing down along the length ot the valve andl back betere it discharges. The ceci duid is preferably passed irs't in naso-,vea

contact with the wall of the inlet manifold, so that the outer surface of the valve is kept cool, and back in contact with the hotter wall- .the pipe 49, the fan 31 in this instance bein arranged to discharge the cooling iui The joints between the tubes 25 and 26 and the. stationary structure of the engine head are closed by suitable stuiling boxes 51 and 52 to prevent leakage. ln this construction, the wall 25 is simi-circular in form at intervals and is provided at intervals with danges 53 secured to the outer tube 18, thereby opening the passages between the tubes 25 and 26 to the outer tube 18 and bringing the coolin Huid in direct contact with the outer tu e.

The chambers so formed behind the outer tube 18 are arranged so that they register with the cylinder ports 1li as the valve rotates, so that the areas of thelouter tube lwhich are subjected to the hot gases of explosion are water jacketed on their rear surface, so that they are kept cool.
