INTERNAL-COMBUSTION ENGINE.
Specification of Letters Patent.
Patented Mar. 30, 1915.
Application filed July 17, 1912.l Serial No. 709,927.
This invention relates to internal combustion engines of the type shown in my applications No. 514,098 tiled August 23, 1909 and No. 568,612 filed June 24th, 1910. In the construction disclosed in these two applications, each cylinder is provided with a pair of valves, namcly-an inlet valve and an exhaust valve, the valves being of the slidable sleeve type located at one sideof and substantially parallel with the cylinder and sliding between a cylindrical surrounding casing and an internal liner sleeve, the outer seat or casing and the liner sleeve forming an annular slide-way for the valve. In the form of my invention shown in the later application above-mentioned, the upper end of the sleeve is exposed, whereby it is possible for a slight pumping action to occur upon the inlet and exhaust pipes (according as the valve is an inlet or an exhaust valve) although such action is necessarily small, owing to the limited cross-sectional area of the upper or exposed end of the valve sleeve. In both forms of myin vention disclosed in the aforesaid applica` tions, an abutment is anchored within each valve (being preferably formed with the liner) at one sid v of the registering ports of the liner and the valve seat, whereby the gaseous mixture entering the inlet valve and the exploded gases entering the exhaust valve will be deflected and the gases will be prevented from entering the crank case or the case which contains the lay shaft by which the valves are driven.
In the embodiment of my invention disclosed herein` I entirely eliminate the slight pumping action referred to by connecting the abutment (which may be conveniently carried by and movable with the liner sleeve) with the lay shaft and so connecting the abutment and the valve that their phases will be practically in opposition to each other; that is to say, when the valve is ascending, the abutment is descending, and
vice versa. Furthermore, owing to the far greater cross sectionall area of the abutment than that of the valve, I give to the liner and its abutment a length of stroke which is inversely proportional to the cross seictional areas of the reciprocating parts. The result is to entirely balance or olf-set the slight pumping action due-to the exposed cross sectional area of the ring or annulus of the valve.
In the drawing forming part hereof,
'Figure l represents a View, partly in side elevation and partly in vertical section, of an engine constructed in accordance with my invention, and Fig. 2 a sectional View taken through one of the valves, at right angles to the plane of section in Fig. 1.
Describing by reference characters the various parts illustrated herein, 1 denotes the base section or crank case of an engine, the engine being shown as of the fourcycle type comprising generallythe cylinder 2 having a casing 3 surrounding and forming a water jacket therewith, the liquid within the water jacket and parts being indicated generally at 4. Each cylinder is provided with a cover section 5 and with a spark plug 6, which may be carried by a bushing 7 threaded into the" top of the cylinder. i
Cast with each cylinder 2, but preferably spaced therefrom a short distance, is a valve casing,'said casing being preferably a cylindrical sleeve 7 having about midway of its length a series of segmental ports 8, the series extending substantially entirely around the sleeve and communicating with a duct 9 carried by and merging with the head of the cylinder 2. This sleeve depends from the cover section 5, being preferably cast with the cylinder head and with the wall of the duct 9, and is provided at its lower end with a ring 10 threaded thereon and abutting against an inwardly directed flange 11 carried by the vcasing 3, the flange extending entirely around the sleeve -and forming the top of the chamber which contains the lay shaft. A packing ring` 12 is inserted between the top of the ring 10 and the flange 11.
lVithin the sleeve 7 is mounted the tubular slide valve 13, said valve being-cylindrical in shape and being connected at its lower end by a pitman 14 with the cr nk 15, which projects from the lay shaft 1 The Valve 13 is provided about midway of its length with a series ol segmental ports 1? adapted to communicate with the corresponding ports 8 in the outer sleeve or valve casing 7. Within the slide valve 13 there is mounted a liner or bushing 18, saidy liner or bushing having ay transverse partition or abutment 19` extending thereacross immediately below a series of segmental ports 2O which corresoond to and are adapted to register with the ports 8 and 17. The liner 18 and the valve casing 7 provide an annular valve seat for the cylindrical slide valve and, in order to prevent leakage between the sleeve 7 and the liner 18, the valve is provided with packing rings 21 and the liner with packing rings 22. the packing rings in each case being located above and belov.v the segmental ports of their respective supporting members. The cover' section 5 is provided with suitable openings in its top above the inlet and exhaust valves, an opening for one of such valves being shown in the drawings and being covered by the plate 23, which may be conveniently and removably anchored by means of the bolt 24 having a cross head 25 at its lower end adapted to eX- tend across the bore of the valve chamber beneath the cover and to engage the flange 26. The cover is secured in place by means of a nut 27 on the upper end of the bolt. The valve shown in the drawing is an out-- let valve, in Which case the Ntop of the valve will communicate by means of a branch 28 With an outlet pipe 29 which may be common to all of the outlet .valves used with the multi-cylinder engine. In such case, the inlet valve, Which is identical in construction with the outlet valve, will be supplied by means of an inlet pipe 30 which may be a. branch from a common supply pipe for all oi the inlet valves of the multi-cylinder engine, as shown in my application No. 568,612.
IWith the construction shown, there "ill be a slight pumping effect on the pipe 28 due to the area of the exposed end of the valve 13. To olf-set this slight pumping action, the liner sleeve 18 and its abutment is connected to the shaft 16 by means of a connecting rod or pitman 31. The connecting rods or pitman 31 and 14 will be connected with the lay shaft 16 at an angle of substantially 180 degrees apart, and the strokes of the connecting rod 31 and 14- will be inversely proportional'to the cross sectional area of. the upper exposed surfaces of the moving parts connected therewith. Furthermore, the parts Will be so arranged that, when the ports 17 are in register with the ports 8, the ports 2O will also be in register with the ports 17.
,As in the disclosure of my prior invention,
t' e rear or outer parts of the duct 9, which is formed with the valve seat 7, will be lateri fluid through allydelected to forma channel 32 surrounding the portion of each valve sleeve which is remote from the cylinder head, thus producing a balanced construction which minimizes the tendency of the valve sleeve to bind and causes it to wear evenly in its seat. The partitions or abutments 19 not only serve to direct the incoming and outgoing gases, but isolate'the crank case and layshaft chamber from such gases.
