H. LESNIAK, WIEN, OSTERRIKE. nrbranningsmotor med i varandra lopande, motgitende kolvar. H. LESNIAK, VIENNA, AUSTRIA. no-combustion engine with interlocking, reciprocating pistons.

Uppfinningsforemalet utgores av en forbranningsmotor med i varandra lopande, motgaende kolvar, genom vars konstruktionssatt ernas betydande utrymmes- och viktsbesparing. The object of the invention is an internal combustion engine with reciprocating, reciprocating pistons, through the construction of which the significant space and weight savings of the construction kits.

Dessa fordelar ernas enligt uppfinningen darigenom, att vid den med en sarskilt forstarkt vagg forsedda yttre kolven är ledbart fast en enda veystake, vilken verkar pa en andvevtapp pa en i en avtagbar platta eller dylikt lagrad, endast for en enda cylinder utformad vevaxel. These advantages are achieved according to the invention in that in the case of the outer piston provided with a particularly reinforced cradle, a single connecting rod is articulated, which acts on a ducting pin on a crankshaft designed in a removable plate or the like, only for a single cylinder.

Pa della satt är det tillrackligt med tva vevstakar, i motsats till de kanda, tre vevstakar uppvisande motorerna med I varandra motlopande kolvar. In some cases, it is sufficient to have two connecting rods, in contrast to the known ones, three connecting rods having the motors with mutually opposite pistons.

Vid den i forhallande till andveven motsatta anden av vevaxeln kan ett kugghjul anordnas, medelst vilket .effekten av flera sadana .cylindrar kunna dverforas pa en samlingsaxel. Vevaxeln blir genom ,detta i huvudsak syrnmetriska konstruktionssatt kort och Hitt. In the case of the spirit of the crankshaft opposite to the end crank, a gear can be arranged, by means of which the effect of several such cylinders can be transmitted on an assembly shaft. The crankshaft is through, this mainly syrmetric construction set short and Hitt.

Genom den ensidiga fOrtjockningen av den yttre kolvens vagg gives majligheten .att fOrlagga resultanten .av masskrafterna pa sidan om cylinderaxeln och kompensera det genom vevstakens anbringande vid sidan av den yttre kolven uppkommande, .ornkring en mot cylinderaxeln vinkelrat axel vridande momentet, sã att en .ensidig tryckbelastning mellan cylinder och kolv resp. tippande krafter forebyggas. En sarskild ftirdel med konstruktionen enligt uppfinningen är vidare att cylindern tillsarnmans med plattan och den darpa lagrade vevaxeln pa enkelt satt kan borttagas utan .att, som vid de vanliga, flera ganger bojda vevaxlarna, vederborande vevstake behover lossas. By the one-sided thickening of the cradle of the outer piston, it is possible to place the resultant of the mass forces on the side of the cylinder shaft and compensate for the torque arising by placing the connecting rod next to the outer piston around a shaft perpendicular to the cylinder axis. unilateral compressive load between cylinder and piston resp. tipping forces are prevented. A special advantage of the construction according to the invention is further that the cylinder together with the plate and the crankshaft bearing can be easily removed without, as in the case of the usual, several times curved crankshafts, adjacent connecting rods need to be loosened.

I ritningen visas schematiskt ett utforingsexempel enligt uppfinningen. Fig. 1 .och 2 visa langdsnitt genom vevaxeln med de bada kolvarna i varderagranslage. Fig. 3 visar ett mot fig. 2 svarande snitt vinkelratt mot vevaxeln. The drawing schematically shows an exemplary embodiment according to the invention. Figs. 1 and 2 show longitudinal sections through the crankshaft with the two pistons in each bearing. Fig. 3 shows a section corresponding to Fig. 2 perpendicular to the crankshaft.

Cylindern 1 Or anbragt ph en platta 8 och fOreter vid i ovrigt vanlig utformning tva dubbelventilkammare 21. Harvid -aro tva ventiler 17 anordnade f Or den yttre och tva ventiler 18 for den inre cylindern. Pa ritningen fig. 3 Or endast yardera en av dessa ventiler synlig. De bada andra ligga i fig. 3 bakom de synliga ventilerna. The cylinder 1 is arranged on a plate 8 and, in an otherwise usual design, has two double valve chambers 21. Two valves 17 are arranged therefor, arranged on the outer side and two valves 18 for the inner cylinder. In the drawing fig. 3 Or only one of these valves is visible. The other two are in Fig. 3 behind the visible valves.

I ihaligheten 15 i cylindern 1 Or kolven anbringad, vilken Or forsedd med kolvringar ,och inloppsslitsar 22 och verkar ph vevaxeln 11 medelst vevstaken .6. Vevstaken 6 Or skjuten p0 0 ena sidan andvevtappen. 6, och 0 andra sidan p0 tappen 5, vilken Or i ett stycke med en langsgaende platta 7, vilken är infogad i kolvens 2 vagg. Tappen 5 styres vid sin fram- och aterrorelse genom en ranna i cylindervaggens innersida varvid samtidigt tappens 5 och armed Oven kolvens 2 vridning omkring cylinderaxeln fOrhindras. In the cavity 15 of the cylinder 1 Or the piston is fitted, which Or is provided with piston rings, and inlet slots 22 and acts on the crankshaft 11 by means of the connecting rod.6. The crankcase 6 Or slid on one side of the duck pin. 6, and 0 the other side of the pin 5, which Or in one piece with a longitudinal plate 7, which is inserted in the cradle of the piston 2. The pin 5 is guided during its reciprocation by a groove in the inside of the cylinder shaft, at the same time preventing the rotation 5 of the pin 5 and the armed Oven piston 2 about the cylinder axis.

I kolvens 2 excentriska halighet 16, i vilken gasblandningen inkonnner genom ovan ndmn- da22 befinner sig den pi kant satt med kolvringar fOrsadda, ingen nyhet uppvisande kolven 3, vilken genom vevstaken 4 Oven verkar pa vevaxeln 11. Bada kolvarnas slagvolymer valjas med horde! lika stora. In the eccentric cavity 16 of the piston 2, in which the gas mixture enters through the above-mentioned 22, it is located on the edge set with piston rings provided, no novelty having the piston 3, which through the connecting rod 4 also acts on the crankshaft 11. Both piston stroke volumes are selected with horde! as big.

Den i p0 undersidan av grun:dplattan 8 anordnade lager 19 vridbara vevaxeln 11 vrider medelst kugubjulet 10 ett ph. kamaxeln 20 sittande kugghjul 9, varigenom de pa kant salt i styrningar 24 glidande ventillyftarna 23 manovreras. The crankshaft 11 rotatable in the underside of the base plate 8 rotatable by means of the gear wheel 10 rotates a pH. camshaft 20 seated gears 9, whereby the valve lifts 23 sliding on the edge salt in guides 24 are maneuvered.

Alla axlar och -vaxlar aro inneslutna i en skyddskapa 14, pa vilken plattan 8 Or fastsatt och som samtidigt tjanar som lager for samlingsaxeln 13. All shafts and shafts are enclosed in a protective cap 14, on which the plate 8 is attached and which at the same time serves as a bearing for the collecting shaft 13.

Motorns arbetssatt Or fOljande: Takterna insugning, kompression, expansion och utblasning i en av de hada cylindrarna motsvara takterna kompression, expansion, utblasning och insugning i den andra cylindern. Engine operation Or FOLLOWING: The rates of intake, compression, expansion and exhaust in one of the hot cylinders correspond to the rates of compression, expansion, exhaust and intake in the other cylinder.

Fig. 1 visar dodpunktlaget efter insugning i den yttre cylindern (rummet 15) och efter kompression i den inre cylindern (rummet 16) eller .efter expansion i den yttre och efter utblasning i den inre cylindern. Fig. 2 och 3 visa cla dodpunktlagena efter kompression i yttre och efter expansion i hire eller efter utblasning i den yttre och efter insugning 1 den inre cylindern. Fig. 1 shows the dead center layer after suction in the outer cylinder (space 15) and after compression in the inner cylinder (space 16) or after expansion in the outer and after blow-out in the inner cylinder. Figs. 2 and 3 show the cla dead center layers after compression in the outer and after expansion in the hire or after blow-out in the outer and after suction in the inner cylinder.

Varje cylinder kan pa. enklaste satt demonteras, i det att cylindern 1 tillsammans med grundplattan 8 lossas frail kapan 14. 2— — Skulle en av kolvarna bli obrukbar, sd avsthnges endast dess bransletillfOrsel. Motorn kan dá dna ,arbeta, vilket dr av betydelse saxskilt vid flygplan. Genorn urkoppling av kugghjulet 10 kan cylinderns verkan pd samlingsaxeln 13 frankopplas. Each cylinder can pa. The simplest way is to disassemble, in that the cylinder 1 together with the base plate 8 is loosened from the cover 14. Should one of the pistons become unusable, then only its fuel supply is suspended. The engine can die, work, which is important for scissors in aircraft. By disengaging the gear 10, the action of the cylinder on the shaft 13 can be disengaged.
