PATENTAMT.PATENT OFFICE.
Die Entlastung des Einlaßventils bei Zweitaktexplosionskraftmaschinen durch Vorschaltung eines besonderen Luftsteuerorgans ist nur so lange wirksam, als dasselbe den Inhalt der Ladebehälter abschließt. Eine dauernde Entlastung des Einlaßventils von den absoluten Ladedrücken und Druckschwankungen bietet es nicht. Es ist aber weniger der Einfluß der absoluten Ladedrücke auf das Einlaßventil, als derjenige der starken Druckschwankungen gerade während der Ladeperiode (welcher sich in einem starken Überdruck der Ventilfeder äußert und so leicht den Schluß des Ventils mit starkem Schlag herbeiführt), welcher beseitigt werden muß.The relief of the inlet valve in two-stroke explosion engines by connecting a special air control organ, it is only effective as long as the same is the content the loading container locks. A permanent relief of the intake valve from the absolute It does not offer boost pressure and pressure fluctuations. But it is not so much the influence the absolute boost pressures on the intake valve than that of the strong pressure fluctuations especially during the charging period (which manifests itself in a strong overpressure of the valve spring and so easily closes the valve with a strong blow), which must be eliminated.
Eine dauernde Entlastung des wegen der hohen Temperaturen erforderlichen Einlaßventils bietet dagegen ein Entlastungskolben nach vorliegender Erfindung. Durch denselben wird der Einfluß der Ladedrücke und Druckschwankungen auf das Ventil vollständig aufgehoben.A permanent relief of the intake valve required because of the high temperatures on the other hand, offers a relief piston according to the present invention. Through the same the influence of the boost pressures and pressure fluctuations on the valve becomes complete canceled.
Man kann bei Verwendung desselben die Ladedrücke zur Erzielung eines hohen Füllungsgrades der Maschine beliebig hoch wählen und den Ladebehältern in Rücksicht auf die Anlaßfähigkeit der Maschine beliebigen Inhalt geben, ohne einen Ventilschlag dieserhalb befürchten zu müssen.When using the same, the boost pressures can be used to achieve a high degree of filling The machine can be selected as high as desired and the loading containers can be of any content in consideration of the startability of the machine without having to fear a valve slam for this reason.
Nach der Patentzeichnung ist der Entlastungskolben b auf der Spindel c des Einlaßventils α direkt hinter diesem angeordnet. Er'bewegt sich in einem zylindrischen Gehäuse d, dessen abgeschlossener Raum i mit der Atmosphäre durch eine Rohrleitung h in Verbindung steht. Das Gehäuse d wird gebildet als Fortsetzung des Gehäuses / vom Gassteuerorgan g. According to the patent drawing, the relief piston b is arranged on the spindle c of the inlet valve α directly behind it. It moves in a cylindrical housing d, the closed space i of which communicates with the atmosphere through a pipe h. The housing d is formed as a continuation of the housing / gas control element g.
Durch diese Anordnung wird der Inhalt des schädlichen, mit Gemisch angefüllten Raumes, welches beim Ausspülen des Zylinders in den Auspuff getrieben wird, auf ein geringes Maß beschränkt. Ferner wird den in Bewegung befindlichen Gasen durch den entsprechend geformten Entlastungskolben eine allmähliche, stoßfreie und zwangläufige Überleitung in die Richtung des Ventilaustritts gegeben.By this arrangement, the contents of the harmful, filled with mixture Space that is driven into the exhaust when flushing the cylinder limited to a small extent. Furthermore, the moving gases through the appropriately shaped relief piston a gradual, shock-free and inevitable transition given in the direction of the valve outlet.
Die Entlastung des Einlaßventils kann auf diese Weise auf jeden beliebigen Grad von Genauigkeit durchgeführt werden durch entsprechende Bemessung des Durchmessers des Entlastungskolbens b. Man kann hierdurch den Einfluß des Ladedrucks entweder vollständig aufheben oder künstlich einen beliebigen Überdruck auf Öffnung oder auf Schluß des Ventils herbeiführen und dadurch die Massenkräfte der bewegten Steuerteile ausgleichen.The relief of the inlet valve can in this way be carried out to any degree of accuracy by appropriately dimensioning the diameter of the relief piston b. You can either completely cancel the influence of the boost pressure or artificially bring about any overpressure to open or close the valve and thereby compensate for the inertia forces of the moving control parts.
Durch den Boden k des Entlastungsgehäuses d wird der Gaskanal vom Luftkanal vollständig getrennt. Dadurch wiederum wird das Gassteuerorgan g von der Einwirkung etwaiger Druckschwankungen zwischen Gas und Luft entlastet.The gas duct is completely separated from the air duct by the bottom k of the relief housing d. This in turn relieves the gas control element g from the effects of any pressure fluctuations between gas and air.
Der abgeschlossene Raum zwischen Gassteuerorgan g und Trennungswand k einerseits und zwischen Entlastungskolben c und Trennungswand k andererseits kann noch als Puffer beim Schluß der Steuerorgane ver-The closed space between gas control element g and separating wall k on the one hand and between relief piston c and separating wall k on the other hand can still be used as a buffer when the control elements are closed.

wendet werden. Durch entsprechende Einstellung der Drosselhähne i und η kann die Pufferwirkung einstellbar geregelt werden.be turned. The buffer effect can be regulated in an adjustable manner by setting the throttle valves i and η accordingly.
