Application filed January 11. 1910 Specification of Letters Patent.
Patented Nut. 28. 1911.
Serial No. 537.523,
To all whom it may concern:
Be it known that l, Jenn Enwnnn Selina, a Subject of the King ol Great Britain and Ireland, and residing at ltvdal Mount, ll olders ,llill, llcndon, in the county of Middlesex, England, have invented certain new and useful Improvements in the Valves of Iuternal-Combustion Engines, of which the following is a specification.
This invention relates to valves of the to tary cylindrical type for internal combinilion engines. and ban for its objects to simplify the cmistruction oi such valves and particularly to a oid (ii tortions of the valve due to unequal expair io'n caused by the (lit ference n the temperature ol the gilfitir; pan inn through the same.
In the acct'impanying drawings, which show. by way of example. two mode,- in which my invention may be curried out. Figure 1 i8: 27. fragmentary view in longitudinal section. Figq- 2 and are cross sections; taken on the lines .v--:c and c oi hill. 1, showing the application of my in ention to a tworvlindcr engine in which the ranks are set at. an angle of 18!) Fig. 4 is an end view ol the tubular valve owing;- u Il'iOdlfiCtlllOfl in i1:on:=trn -iion. Fig. 5 in a +c=-- tional view showing the annular valve ill"- rangcd. transrerscl to the line of the \w l'lb ing cylinders and controlling the. ports of two cylinders of a nnilti-rylinder engine.
In carrying out my invention acc rding:
' wrwlv to the lllih ol' the working cylinders to one mode, as illustrated in Figs. l to 3. an outer valve cyliiulcr a for containing the rotary valve arranged longitudinally above the heads of the norlring cylinders b b of the engine being connected with the combustion rdmmtwrs of .mid Ylll".tl(lt-l by suitably arranged and proportioned 1)(H'l:-; c c. Arranged concentrically within the outer valve cylinder 0. is a second valve cylinder d, which is secured to or forms an extension of the exhaust pipe (2 and which is provided with ports f f corresponding with the ports 0 a connecting the outer valve cylinder a with the working cylinders I) I). A tube 9 of annular form tits on the annular space between the two valve cylinders n and d, and its outer wall is provided with ports 7:, so shaped and arranged that the operate to put said'valve into eounnunication with the cylinders I) through the nuts 1: 0. Passing through the annular valve r/ are the ports '5 i, so shaped and arranged that they operate to put the working cylinth snppl ders 1 ?i into communication with the inner valve cylinder 04 through the ports 0 and f. The one end of the annular valve 9 projects through one end of the outer valve. cylinder u. and carries a skew gear wheel m throu h which motion is imparted to it from t e crank shaft, the speed of the annular valve being preferably half that of the crank shaft. The other end of the annularvalve terminates within the outer valve cylinder (1 no as to torn: a chamber 11 which is in cornmunication with the inlet pipe 0 by means a suitable port or peso-age p. 4 hither the outer valve cylinder a or the inner valve cylinder a? or both as shown in the drawings. may be water-jacketed, and Although i have described the inner valve cylinder as being used as the exhaust tube and tlw annular valve aslwing connected to the inlet. pipe. the disposition and functions of these inn 1m rts may he rote-med.
To Facilitate the {low of the charge through the inlet pip. mul annular r l or l'ilrulca may be formed at th r of the an nlar rulvc g so as 1L fniblih'u ii 'iiiil.
in an alternative form of Lild face a may make the annular valve with both ends trim-ed, in which cuee :1 p rt or ports will be pr v ded in the roll of w ll annular valve to writ an :i ui aiw f coinnninicalion with ttinl ethanol arranged trans- .o that one \nlve com ole the ports of two working cylinders.
My invention is equally applicable to single r-yliiuler engines as well as to engines having; a plurality of working cylinders, and it will also be obvious that the annular valve may be driven at. any desired speed in relation to the speed of the crank-shaft, by a proper disposition of the inlet. and exhaust ports.
Ha ring now described my invention what 'I claim as new and desire to secure by Letters Patent is:
1. Valve mechanism for admission and exhaust-of an internal eon'ihustion engine comprising in combination two fixed con centric valve cylinders and a hollow annular valve working in the. annular space between said cylinders.
2. Valve mechanism for admission and exhaunt, of an internal combustion engine comprising in combination two fixed concentr ic "nos.
valve cylinders, and a hollow annular valve rotating in the annular space between said cylinders, and means for rotating said annular valve.
3. Valve mechanism for admission and 0xhaust of an internal combustion engine comprising in combination an outer fixed valve cylinder rovided with ports communicating with t 1e working cylinders of the engine, an inner fixed concentric valve cylinder having ports corresponding with the ports in the outer valve cylinder, a hollow annular valve open at one endjantl closed at the other end and rotating in the" annular space between the valve cylinders, and means for rotating said valve.
4. Valve mechanism for admission and exhaust of an internal combustion engine comprising in combination two fixed concentric valve cylinders, a hollow annular valve rotatin in the annular space between the said va ve cylinders, said annular valve being open at one end and closed at the other, vanes inside the open end of said annular valve, and means for rotating said valve.
5. Valve mechanism for admission and exhaust of an internal combustion engine comprising in combination an outer valve cylinder provided with ports communicating with the working cylinders of the engine, a water jacket for said valve cylinder, a fixed inner valve cylinder concentric with said outer valve cylinder, a water jacket for said inner valve cylinder, a hollow annular valve rotatin in the annular space between said valve cy inders and means for rotating said valve.
6. Valve mechanism for admission and exhaust of an internal combustion engine comprising in combination an outer valve cylinder having ports communicating with the workin cylinders of the engine, a water jacket or said valve cylinder, an inner valve cylinder fixed concentrically within the outer valve cylinder and having ports corresponding with the ports in the outer valve cylin' dcr, a water jacket for said inner valve cylinder, a hollow annular valve open at one end andclosed at the other and rotating in the annular spacebetween said valve cylinders, vanes inside the open end of said annular valve, and means for rotating said valve.
In testimony whereof I afiix my signature in the presence of two witnesses.
