This invention relates .to single-acting and .doublefacting internal 'combustion engines -place in wellknown 0 manner through the v piston channels.
The distribution Ais con- `;trolled by, acrossfpinin the piston which,l
siny a manner known Iper se,`ei"ects the driving of the vcrankshaft-and which, with this ob- .ject in view, is constructed as a hollow body ,(cylindrical slide piston andV having* recesses,A the gas mixture VVentering-,fat the one side into this hollow v 'drical ,cross pin.
body'and the gases from combustion esc-apr ing at the other vside fromv theV saine. The
distribution may however be effected by slide valves which are arranged outside the piston at either lend -of the rotatable hollow cylin- .low and have recesses on their vinner sides whichcorrespond with the outwardly directed channels of they piston.` The. admission ofthe gas mixture into the one slide valve and the exhaust of the gases of the combusvtion from vtheoth'er slide vvalve takes place through the hollow space of cross -pin sub-` divided bya partition@ Owingtofthe'slide valves being situated outside the combustion or explosion space the security of service of the engine is increased. The slides *reciprocating withthe piston 'are rotated from the crank shaft. The movement of the crankshaft .is transmitted to the slide valves preferably by a chain-gear,
axis of the crank shaft while being rotated similar gear.v A suction chamber i is preferably arrange-d in front of the admission channel, said suction chamber-being situated entirely or partly inthe crank casing so that inarily heated.
' An embodiment of such double-acting internall combustion engines is'shown, by way of example, on ythe accompanying drawing. in which: f
Fig. l is a vertical section, v'and Fig. 2' a horizontal section.
' Referring to the drawings 7' arethe cylin-` ders and b is the piston common to thetwo cylinders. This piston has in well known manner on the one side thev admission channels c and on the other, side the exhaust lchannels d. .Each admission and exhaust valve) rotating with :the deliver the These slide valves are holthesprocket wheel, of which is' keyed on the crank shaft-turns around" the a distribution fori channel terminates in a compression..y space e" of the piston the cross pin 2 ofthe piston :which in the `The rotary slideval'ves L yare hollow and .serve to deliver thel combustible'mi'xture to they compression spaces of the piston and to gases lof .combustion Vfrom the cylinders. With the cross pin`2 the connecting rods y, g of the crankshafth are hingedly connected in a manner vknownfper se.' fTlie vcrank shaft communicates to the slide valves a their rotating movementthrough the ina are rotary slide valves having apertures or recesses andy rotatably mounted at either side outside `the piston on tl() `well known manner drives the, crank shaft.
termediary of a chain gear mthe sprocket wheel n of which arranged at the side kof the crank shaft #executes a circular movement around the axis of the crank shaft, L vbeing l at I' thefsame time rotated `from ,this crank f shaft by meansof a spurwheelgear c', Ic. `The spur wheel is mountedon a partition u; of the casing .u an'd'thespu'r `wheel c is rigidly vonnected with the sprocketwheel (m by means of a bolt Z. t l i Il All the transmitting elements are arranged outside the, piston 4and outside the cylinders... lThe crank casing u ofthe internal combus-` tion engine contains also the piston and the distribution. vIn front of the admission channel of each slide valve e asuction chamber 'w' is arranged which is partly situated in the casing u, so that the combustible mixture is preliminarily heated. The exhaust port of lthe cross pin 2 ofthe piston opens into the exhaust channel g. The suction chamber' w aswell as the exhaust x are coveredand packed with regard to the casing u byk dampers y. lin front ofthe orifice of the exhaust i i channellq and upon `the contents 'of-fthecas- 1 90 .ing u whereby a vacuum is produced inthe suction channel g..v The gases of combustion are consequently 'removed more rapidly from the cylinder wherefrom results an increase of efficiency of the engine. Theblades of 105 the fly wheel p suck further'through o'hot` yair from out of the casing@l and at the y'samev l time fresh air into the same through 'the opening a. The fresh air flows alongfthe slide valves e and cools the same. vIn each lfll channel q and in front of'theoriice of a 95 I;
` cylinder y7^ a tubular socket s is arranged into which the spark plug is inserted. t is the magneto which is driven from the crank .shaft t by means of a corresponding gear. A change speed gear can'be mounted in the crank casing u and ribs n (Fig. l) can loe mounted on the outer surface of the same which are o-bliquely directed forward and downward. In this manner it is possible to admit air permanently to the rear cylinder 1 as indicated in Fig. l by the arrow and to cool at the same time the oil in the crank casing.'
The engine may be a two-stroke or a four- -stroke motor.
I claim i. rin internal combustion engine, in which the admission and exhaust are effected through slots in the piston, comprising in combination with a cylinder and a piston having an admission slot and an exhaust slot and a crank shaft, a hollow cross pin open at both ends in said piston, connecting rods connecting said cross pin with said crank shaft, means for indirectly rotating said cross pin from said crank shaft, a partition in said hollow cross pin said cross pin having at either siue of said partition admission and exhaust apertures, hollow rotary slide valves on said cross pin one at either side of said partition and havin r apertures registering with said apertures or' said cross pin and apertures registering with said admission and exhaust slots of said piston so that the gas mixture flows through one half of said hollow cross pin into the corresponding rotary slide valve and thence through nseaezs the admission slots into said piston from which piston the exhaust gases flow out into said other rotary slide valve and thence through the other half of said cross pin.
