Description
Schiebersteuerung für Zweitaktmotoren mit Stufenkolben. Vorliegende Erfindung betrifft Beine Schiebersteuerungfür Zweitaktmotoren mit Stufenkolben, bei welcher letzterer die Verdichtung des Gemisches :im Kurbelgehäuse und das Absaugen der verbrannten Gase bewirkt.Slide control for two-stroke engines with stepped pistons. Present Invention relates to legs slide control for two-stroke engines with stepped pistons, in which the latter the compression of the mixture: in the crankcase and the suction of the burned gases.
Die Schiebersteuerung hat die Einrichtung, daß seitlich am Absaugzylind-er ein hin und hier gehender Steuerschieber angeordnet ist, der sämtliche Phasen der Verteilung steuert und äußere Ringnuten besitzt, von .denen eine den Zugang .der frischen Gase unter den Kolben und die andere das Auslassen der verbrannten Gase .aus dem Absaugzylinder während des ganzen Aufwärtsganges herbeiführen, während ein @innerer Hohlraum des Schiebers in bekannter Weisernur als Durchgangskanal für die frischen Gase von der Kompression skammer unter dem Kolben nach der Explosionskammer dient.The slide control has the device that on the side of the suction cylinder a back and forth going control slide is arranged, the all phases of the Distribution controls and has outer ring grooves, one of which has access fresh gases under the flask and the other releasing the burnt gases . bring it out of the suction cylinder during the entire upward movement, while an inner cavity of the slide is known only as a passage channel for the fresh gases from the compression chamber under the piston after the explosion chamber serves.
Eine solche Schiebersteuerungerreicht, daß die verbrannten Gase 'bei ihrer ,Nusströmung keimen höheren Druck als den atmosphärisc'henbesitzen, daß der Kolben bei seinew 'Niedergang mit einer den unteren Kolibent.Cil darstellenden Verbreiterung auf seiner einen Seite die frischen Gase komprimiert, während er andererseits einen Unterdruck in einer Kammer erzeugt, so daß die verbrannten Gase vollkommen aus der Explosionskammer in diese Zylinderkammer hiinei'ugesaugt werden, sobald der Kalben die die beiden: Kammern miteinander verbindenden Bohrungen bzw. Kanäle öffnet.Such a valve control achieves that the burned gases' at their nut currents germinate higher pressure than the atmospheric ones that the Piston at seinew 'companionway with a widening showing the lower Kolibent.Cil on one side it compresses the fresh gases, while on the other side it compresses one Negative pressure is created in a chamber, so that the burned gases are completely out of the Explosion chamber can be sucked into this cylinder chamber as soon as the calving which opens the holes or channels connecting the two chambers.
Durch den erzeugten Unterdlruck werden die verbrannten Gase angesaugt und bei dem Aufwärtsgang des Kolbens durch die Kolbenverstärkung ausgetrieben.The burned gases are sucked in by the negative pressure generated and driven out by the piston reinforcement in the upward gear of the piston.
Die Sdhiebersteuerung ist irreinem Ausführungsbeispiel auf beiliegender Zeichnung urgestellt.The gate valve control is in a purely exemplary embodiment on the enclosed Original drawing.
Abb. i zeigt -einen Längsschnitt durch -die Steuerung in demjenigen Augenblick, in dem der Kolben seine untere Totpunktlage @erreicht hat. Abb. 2 veranschaulicht einen Längsschnitt bei oberer Totpunktlage des Kolbens.Fig. I shows a longitudinal section through the control in that one Moment at which the piston has reached its bottom dead center position @. Fig. 2 illustrates a longitudinal section with the piston top dead center.
Der Zylinder besitzt zwei Teile i und 2 von verschieden weiten Bohrungen. In. diesen verschieden weiten Zyl.in@d@erbahrungen i und 2 bewegen sich einerseits -der eigentliche Kolben 3 und andererseits die Kolbenverstärkung 4. Der Zylinderteil i ist durch einen Vorsprung 5 in .den weiteren Zylinderteil -2 hiinein verlängert, wobei der Vorsprung 5 eine Anzahl von Durchbrechunäen 6, 6 aufweist, die die Explosionskammer mit der ringförmigen Kammeer 7 zwischen .dem Kolben 3 und dem mit weiter Bohrung versehenen Zylinderteil 2 verbinden. Kolbenringe 8, 8 bewirken die Abdichtung,des Kolbens.The cylinder has two parts i and 2 of bores of different widths. In. On the one hand, these differently wide Zyl.in @ d @ erbahrungen i and 2 move -the actual piston 3 and, on the other hand, the piston reinforcement 4. The cylinder part i is extended into the further cylinder part -2 by a projection 5, the projection 5 having a number of perforations 6, 6 which form the explosion chamber with the annular chamber 7 between .dem piston 3 and the one with a wide bore Connect provided cylinder part 2. Piston rings 8, 8 create the seal, des Piston.
Der Zylinderteil besitzt den Wasserkühlmantel 9 und hat einen Kanal io, -der sich oberhalb der Durchbrechungen 6, 6 des Zylinderfartsatzes befindet. Der untere Zylinderteil 2 besitzt die Kanäle i1, 12, 13, die ihre Fortsetzung in einem am Zylinder befestigten Gehäuse 14 finden.The cylinder part has the water cooling jacket 9 and has a channel io, -which is located above the openings 6, 6 of the cylinder part set. The lower cylinder part 2 has the channels i1, 12, 13, which are continued in a housing 14 attached to the cylinder can be found.
Das Gehäuse 14 weist gegenüber den Kanälen i i und 12 Durcbbrecbungen 15 und 16 auf, von denen die erstere einen größeren Durchmesser aufweist als die letztere. Das Gehäuse 14 ist an seinem unteren Ende offen, um die Einführung des Verteilungsschiebers 17 .zu ermöglichen. Dieser bat einen Hohlraum 26 und besitzt an seinem unteren Ende eine Rolle 18, gegen die .ein auf der Kraftmaschinenwelle 2o befestigter Daumen o.,dgl. ig arbeitet, um, dien Schieber entsprechend den Phasen der Verteilung anzuheben. Eine Feder 21 wirkt auf das andere Ende des Schiebers 17, so daß seine Rolle 18 in ständiger Berührung mit dem Daumen i 9 gehalten wird.The housing 14 has openings in relation to the channels i i and 12 15 and 16, the former having a larger diameter than the latter. The housing 14 is open at its lower end to allow the introduction of the Distribution slide 17. To allow. This asked a cavity 26 and has at its lower end a roller 18 against which .ein on the engine shaft 2o attached thumb or the like. ig works to serve the slider according to the phases of distribution. A spring 21 acts on the other end of the slide 17, so that his roller 18 is kept in constant contact with the thumb i 9.
Der Hohlschieber 17 hat zwei #Durchbredhungen 22 und 23, von denen
22 den Durchgangsweg 26 -des Hdhlsch@iebers mit dem Zylinderteil i zu verbinden
vermag, während die zweite Durchbrechung 23 eine Verbin-
