Two STROKE CYCLE ENGINE. FILED JUNE l0. 1919.
and bottom ot' `the piston i are q" ite i quite iin, so that the ettectire winnie eivept by the pieton et the fuel inimp may he made as large the present conetruction will I permit. The v"le'ature, that the 'Walle not supported by tivo feet but bnly by one,
vizv a tuhe 23 disposed centrally with pect to the Working piston byivay oi? which the .fuel is conveyed toy and from they Working chamber QOO the uel pump. The connecting` rod connecting the engine Working piston Z to the engine crank is replaced by two rods disposed one on eitherl side of the said tube.
By this arrangement there is :,ittained a particularly cheap construction especially f suitable for smaller engines.
` shaft, il.
l"lllhe lower end of `the tube 23 is screwed into a plate 26, which isiastened te the Working' cylinder ot the motor (not shown in this ligure, hut the same as 1).'
The cavity of the tube `communiczutes With a tube 2T attached to the lower side of the plate 26.` The tube 27 communicates with the admission valve 3 (Fig. l) oit the fuel pump and with a channel (4h Fig. l) leading tothe Working chamber of the engine.
i Gonnected to the piston 7 is a plate Q8 vith tivo diametrically opposite cylindrical.
pins 29 and 80 journaled in bearings Si, 2% i in the Wall oit the piston 7. The pitnnni rodeI 24; and 25 are screwed to the plate 25.1, and these rods connect the plate 28 to a ring 33 encircling aerank 34- on the engine In the plate 26, there are providedtwo Slots 35 and 36 affording' passage 'for the rods 24 and 25, so that the latter are `tree to swingtorward and backward following the motion of the crank 34;. in similar manner `there is provided,V in the plate 28, an opening 37 through whichv the tube 23 is inserted and which is so large that the plate 28-inay perform its oscillating Inotion, lWithout being` hampered byV the tube-23,.
Then the engine Works,
and expelled from the Working chamber 2O of the. fuel pump passes in and out lbi1/'Way- ,of the tubes-23 and 27.
ascertained our said inventionand the matthe piston 7, `moves up and down relatively to the staf ltiofnary piston 14, and the uelinhaled into rgine9 comi ter in which the same is to be perfoifined7 We declare that what We claim is l. Ina two-stroke internal combustion enn gine., comprisinga Working cylinder, a stationary piston located Within said .vorlnni;` cylinder having` external packing, and a hollovv Working piston reciproca'ting` Within the Working cylinder and on the paclsed outer eur-piece of said stationary piston to :term a combustion chamber- Within thefivorling cyl` inder, and a ifuel `pump and compression chamberbetiveen said pistons, a fuel admireion valve and a passage leading'thence to said compression chamber, a passage leading from such chamberte the inlet to the combi. tionehzimberyand a valve at said inlet, the piston displacement oi"- fuel pump chinber approXimating` that et the workin ch ler heitere the opening ot the exhaust passage, whereby the fuel `is iirst drawn into euch chamber, and during` the combustion stroke is conflpreesed` therein, and expelled theretroin te the combustion chamber.
. ln a t\vo-e'trolre internal combustion enising a Working' cylinder, a staH von concentrically located in. said workingv cylinder7 and having external paoliing;y end hollow Working piston reciprocating Within the Working cylinder and on the outer surface ot said stationary piston, to 'form a combustion chamber Within theyvorling cylinder. rand a compression chamberA between said pistons, theyv ,rlzing cylinder having; an exhaust port uncovered toward the end of] the power stroke, a `fuel admis'- sion valve, a pasf'iage communicating theref from to the compression 'chambeny a passage communicating' from said lchamber to the combustion chamber, and la spring -pressed inlet check -valve admitting; fuel from the latter vp:Lesage to said combustion chamber, 'whereby fuel compressed during` the power stroke and during` the erlmifisteuch compression liuel `torces its Wav throu i the inlet valveinto the combustion chamoer to expel thespent and ic 'further com.- pressed therein during;` the return stroke. i
3 An engine aecording` to claim jl, the etationary'piston iixedly mounted on an upright tubular vsupport attached at its base to the end of the Working cylinder7` and the passage through said support forming part l of the passage leerlingv from the compression chamberto the ifuel inletvalve.
