Appncation 4filed December i7, i919. serial No.l 345,530. u
, To aZZ/wlwm t may concern y Be 1t known thatI, ERNST Scrutin, a citi-Yl Zenof Switzerland, and residing at Annecy,l
Haute Savoie, France, have invented certain new and useful improvements in or Relating to `Reciprocating Engines, of VWhich the following is a specification. i
VThis invention relates to 'an improvement in'Av orV mcdiiication lof the apparatus Vdescribed U. S. Patent No. 1,213, 274 of lan-` uary 23, 1917, .for preventing. leakage past p the'v hollow Spindle of the slide valve Otan' engine.
This apparatus comprises'an expansion chamber which surrounds the guide socket of the. said spindle, and in which working Vfluid which has -lealed "into said chamber is stored during the compression,
explosion and exhaust, and is subsequently restored to the 'same Working cylinder dur ing the suction period inV that cylinder, through the said hollow spindle.'V The re- V'.sult of this arrangement is thatthe excess of pressure of the escaped .gases in the e2;- pansion chamber overthei'surrounding pres-- sure is maintained during the Compression, explosion and exhaust periods. Y
The object aimed at by the present invention is completely to avoid the VYsaid excess of pressure in kthe expansion. chamberiof each of the several cylinders of an internal com-v into another` cylinder by thev suction produced at the same instant in this latterl cylinder. Y
Take the case of a four cylinder engine: 1,` 2, 3, 4 provided With Water jackets g' 7 desi gnates a jacketed cover fixed into the cylinders; inside of said covers are screwed casings 8 closed by means'ot covers 9, the 1nterior of each casing forming an expansion chamber 23. Each cylinder has slidingly mounted in it an annular valve 12 adapted to alternately open and close the inlet and outlet ducts (not shown). Said valve is made with across bar 16 to which is coni YSpccication ef'Lctters 3 5-stent. liigntg APL y.nectedfthe rod .17 actingto move the valve and passing through'sleeves 24 and 9Ct integral Withthe casing 8 Vand the cover 9 respectively. Eachiro'd 17is made with an internal channeli19 and nearthe upper fand lowerparts thereof' with ports 2O and21.
In the loivermost position of eac-h rod 17,V
said ports 2O are' positioned opposite the space 24""betvveeii the sleeves 24 and 9a Whilst 4the portsy 21 Will communicate 'with the interior'of 'the respective cylinder 1, 2,
3 r or 4. At the instant explosion takes "place,
inthe cylinder No.1, 'admission takes place in the cylinder No.4.V it, is therefore sufficient to connect togetherthe tivo' corresponding expansion chambers 23 by a pipe'41. lVhenthe Vexplosion takes place in the cylinderNo. 1, Working fluid escapes along the rod 17 and passes into the expansion chami-s, ieee. c
ber itis immediately drawn by thecyl'inder No. 4 through the pipe 41 and the expansion chamber 23 into the said cylinder.
Conversely, at the instant whenv explosion takes place incylinder No. 4, admission takes place the cylinder No.1 and the same thing happens as in the preceding case, but
in thefreverse direction." 'The sameV Willbe the'case in the cylinders i2 and', the tivo expansion chambers of Which Will be forthe sok same vpurpose connected together byk a pipe 41a.
It i'sadvisable to make Ithe arrangement so'that the capacity ot1 vthepassages of the 'tivo expansion ychambers,(ojt' the pipe 'betweenthe two cylinders) should be the same 'for each group of cylinders.
The arrangement shown by Way ci eX- ample for this four cylinder engine is applicable in the same Wayto an engine With six, eight, twelve, sixteen or any even num.- ber oi cylinders. v i
Finally, it is pointed out that the same object could be attainedv by other means, forA I instance by connecting all theVY expansion chambers 23 to one and the same pipe 41 by respective branches such as 41", 41C, as shown in Figure 2, the pipe 41a being then omitted.
sok
The exhaust gases are thus maintained per-V v manently at low pressure by the successive suctions offall the cylinders.

2. In a reciprocatingl engine, the combination, with a series ot' cylinders and valve rods passing through the wall ot' the respective cylinders, of respective expansion chambers surrounding the said respective valve rods and adapted to receive and to allow expansion therein ofgas escaping from the cylinders along the said rods, of conduits permanently connecting each expansion chamber to the other expansion chambers, each valve rod for periodically connecting the respective expansion chamber to the interior of the respective cylinder, for the purpose of allowing the gas in the said chamber and in the chambers communicating with it, to be drawn in through the respective valve rod into the said respective cylinder.
3. in a reciprocating engine, the combination, with a series oit cylinders and valve rods passing through the wall of the respec- Y tive cylinders, of expansion chambers surrounding the respective valve rods and adapted to receive and to allow expansion therein of gas escaping from the cylinders along the said rods, of conduits permanently connecting each expansion chamber to the other expansion chambers, each valve rod for connecting the respective expansion chamber to the interior of the respective cylinder during the suction period, for the purpose or allowing the gases in thesaid chamber and in the chamber or chambers communicating with it, to be drawn through the said valve rod into vthe said cylinder.
4f. ln a reciprocating engine, the combination, with a series of cylinders and valve rods passing through the wall of the respective cylinders, of expansion chambers enclosing the respective valve rods and adapted to receive and to allow expansion therein ot gas escaping from the cylindersaround the said rods, of means for connecting the expansion chamber of each of the cylinders, to the expansion chamber of another of the said cylinders, which is at a different phase of working, each valve rod being provided with means for connecting the respective expansion chamber to the interior ot the respective cylinder during the suction'period ot the latter, for the purpose of allowing the gas in the said chamber and in the chamber communicating with it, to be drawn through the said valve rod into the said respective cylinder.
ln testimony that l claim the foregoing as my invention I have signed my naine in presence of two subscribing witnesses.
