Description
Einrichtung zur Kompressionsverminderung für Notoren mit zwischen der Zylinderwand und dem Kolben angeordnetem rohrförmigen Drehschieber, welcher einen den Ein- und Auslaß abwechselnd öffnenden Steuerschlitz enthält. Die Erfindung betrifft einen Verbrennungs-bzw. Explosionsmotor mit innerem Rohrschieber als Steuerorgan sowie einer Einrichtung zur Verhinderung der Kompression und insbesondere einen Motor; bei welchem zwischen dem Kolben und Zylinder ein umlaufender Rohrschieber mit einem Durchtrittsschlitz angeordnet ist, der während der Drehung des Schiebers nacheinander die für den Auspuff und den Einlaß bestimmten Schlitze des Zylinders freilegt.Device for compression reduction for notors with between the cylinder wall and the piston arranged tubular rotary valve, which contains a control slot which alternately opens the inlet and outlet. The invention relates to a combustion or. Explosion engine with internal pipe slide as a control element and a device for preventing compression, and in particular one Engine; in which between the piston and cylinder a rotating pipe slide is arranged with a passage slot during the rotation of the slide one after the other the slots of the cylinder intended for the exhaust and the intake exposed.
Zweck der Erfindung ist eine solche Ausbildung des Motors, daß beim Öffnen der zur Verhinderung der Kompression dienenden Einrichtung nichtsdestoweniger in den Zylindern des Motors am Ende des Verdichtungshubes eine gewisse Gasmenge unausgetrieben zurückbleibt.The purpose of the invention is such a design of the engine that when Nonetheless, opening the device used to prevent the compression a certain amount of gas in the cylinders of the engine at the end of the compression stroke remains unexpanded.
Dies wird gemäß der Erfindung im wesentlichen dadurch erreicht, daß in dem oder jedem der Zylinder des Motors ein besonderer Schlitz an solcher Stelle angebracht ist, daß er von dem Steuerschlitz des Schiebers zu Beginn der Kompression und während eines Teiles des Kompressionshubes freigegeben wird, wobei der Schlitz in einen Kanal überleitet, der das Innere des Zylinders mit dem eigentlichen Dekompressionshahn in 'Verbindung setzt. _ . Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes veranschaulicht, und zwar zeigt Fig.reinen senkrechten Schnitt durch den Motor, Fig.2 einen Horizontalschnitt gemäß 2-2 der Fig. r.This is achieved according to the invention essentially in that a special slot in the or each of the cylinders of the engine is attached that it is from the control slot of the slide at the beginning of the compression and released during part of the compression stroke, the slot leads into a channel that connects the inside of the cylinder with the actual decompression cock in 'connects. _. The drawing shows an embodiment of the subject matter of the invention illustrates, namely Fig. shows a pure vertical section through the engine, FIG. 2 shows a horizontal section according to 2-2 of FIG.
In dein Zylinder d ist in bekannter Weise zwischen der Innenwand und dem Kolben b ein rohrförmiger Steuerschieber c angeordnet, der mittels einer geeigneten Übertragung von der Kurbelwelle des Motors mit halb so großer Umdrehungsgeschwindigkeit wie diese in Umlauf versetzt wird. Der Schieber enthält einen Schlitz d, der im gegebenen Augenblick und nacheinander den Einlaßschlitz e und den Auspuffschfitz f des Zylinders a öffnet.In your cylinder d is in a known manner between the inner wall and the piston b, a tubular control slide c is arranged, which by means of a suitable Transmission from the crankshaft of the engine at half the speed of rotation how this is put into circulation. The slide includes a slot d which is in the given moment and one after the other the inlet slot e and the exhaust port f of cylinder a opens.
Gemäß der Erfindung ist nun in der Wandung des Zylinders u, und zwar in gleicher Höhe wie die für den Ein- und Auslaß dienenden Schlitze e und. f, ein besonderer Schlitz ä vorgesehen, der von solchen Abmessungen und an solcher Stelle angeordnet ist, daß er von dem Durchtrittschlitz d des Schiebers c zu Beginn und während eines Teiles des Kompressionshubes freigelegt, jedoch von neuem durch den Schieber -abgedeckt wird, bevor vier Kolben b den Kompressionshub beendigt hat. Während des Arbeitshubes, des Auspuffs und der Ansaugung von Frischgas bleibt der Hilfsschlitz g gleichfalls durch den Rohrschieber verschlossen.According to the invention is now in the wall of the cylinder u, namely at the same height as the slots e and serving for the inlet and outlet. fine special slot provided, of such dimensions and in such place is arranged that he of the passage slot d of the slide c at the beginning and exposed during part of the compression stroke, but again by the Slide -is covered before four pistons b the compression stroke quit Has. Remains during the working stroke, the exhaust and the intake of fresh gas the auxiliary slot g is also closed by the pipe slide.
Der Schlitz g ist durch einen Eianal mit dem sogenannten Dekompressionshahn lt, d. h. dem gegebenenfalls zur Verhinderung der Verdichtung dienenden Organ, verbunden.The slot g is connected by an egg canal to the so-called decompression cock lt, ie the organ which may be used to prevent compression.
Wie ersichtlich, beeinflußt der Schlitz g zufolge dieser Anordnung, solange der Hahn h geschlossen ist, die Arbeitsweise des Motors nicht, wenngleich er zu Beginn eines jeden Verdichtungshubes durch den Steuerschlitz d des Schiebers freigelegt wird. Wenn dagegen der Dekompressionshahn geöffnet ist, so wird ein großer Teil des während des Saughubes in den Zylinder gelangten Gases aus diesem durch den Schlitz g, die Leitung gl und den Hahn h wieder ausgestoßen; da indessen der Schlitz g, noch bevor der Kolben den Kompressionshub vollendet hat, durch den Schieber wieder abgeschlossen wird, so verbleibt eine gewisse Ladung in dem Zylinder, die, wenn die Lage und die Abmessungen des Schlitzes g passend gewählt sind, genügt, um das Anwerfen des Motors zu erzielen.As can be seen, according to this arrangement, the slot g influences as long as the cock h is closed, the operation of the engine does not, albeit he at the beginning of each compression stroke through the control slot d of the slide is exposed. If, on the other hand, the decompression cock is open, it becomes a large one Part of the gas that got into the cylinder during the suction stroke ejected the slot g, the conduit gl and the tap h again; there meanwhile the Slot g through the slide before the piston has completed the compression stroke is closed again, a certain charge remains in the cylinder, which if the position and the dimensions of the slot g are chosen appropriately, it is sufficient, to get the engine started.
