Die der hier eingereichten Erfindung zugrunde liegende Aufgabe besteht nun darin, eine Lamellendichtung so zu verbessern, dass die Dichtheit der Arbeitsräume gewährleistet bleibt, die Steuerung des Gaswechsels, d. h. Ansaug- u. Kompressionstakt, Verbrennung, Expansions- und Ausschiebetakt, optimal und mit minimalen Reibungsverlusten ablaufen kann, nur geringe Kurzschlussströmungen auftreten und die Fertigbarkeit der Dichtung in einfacher Weise kostengünstig gegeben ist.The the object underlying here invention is based now is to improve a lamellar seal so that the tightness the workrooms guaranteed remains, the control of the gas exchange, d. H. Intake and. Compression stroke, combustion, Expansion and expansion Ausschiebetakt, can run optimally and with minimal friction losses, only small short circuit currents occur and given the manufacturability of the seal in a simple manner cost is.
Für einen
Rotationskolben-Verbrennungsmotor nach
Die
Dichtfunktion der Dichtlamelle kann durch den Einsatz von beweglichen
Dichtleisten an den axialen Stirnseiten der Dichtlamelle und an
der der Nabe zuge wandten Seite verbessert werden. Insbesondere sind
hiermit Toleranzen und auch der Verschleiß, der während des Betriebes unvermeidbar
ist, ausgleichbar (
Abweichend
von den vorgenannten Anmeldungen
Wie
bei der Einlamellen-Ausführung
besteht bei der Mehrlamellen-Ausführung ebenfalls die Möglichkeit,
an den axialen und radialen Stirnseiten bewegliche Dichtleisten
vorzusehen (

nachfolgenden Beschreibung von bevorzugten, nichteinchränkenden Ausführungsbeispielen
der Erfindung unter Bezugnahme auf die beiliegenden Zeichnungen

Die
Lamellendichtung besteht dabei mindestens aus einer Dichtlamelle

Bei
Verwendung von mehreren Dichtlamellen übernimmt primär der Steuerschieber

Die
Funktion der Mehr-Lamellendichtung ist in
Die
Schmierung zur Reduzierung von Reibungsverlusten an den Einzellamellen,
bei deren Relativbewegung im Betrieb, erfolgt über mindestens eine im Lamellenausschnitt
innerhalb der Trennwand (
Durch die Relativbewegung der einzelnen Lamellen wird zumindest ein Teil des Öls auch an die axialen und radialen stirnseitigen Dichtflächen gefördert, so dass hier ebenfalls eine ausreichende Schmierung vorliegt.By the relative movement of the individual slats becomes at least a part of the oil also promoted to the axial and radial frontal sealing surfaces, so that there is also sufficient lubrication here.
Zur Minimierung der bewegten Massenkräfte sind für die Dichtlamellen und den Steuerschieber insbesondere Werkstoffe mit geringer Dichte vorteilhaft. Gleichzeitig werden aber auch Anforderungen an eine hohe Wärmebeständigkeit, einen hohen Verschleißwiderstand und eine gute, kostengünstigen Herstellbarkeit gestellt, was den Einsatz keramischer Werkstoffe prädestiniert.to Minimization of the moving mass forces are for the sealing fins and the Spool especially materials with low density advantageous. At the same time, however, requirements for a high heat resistance, a high wear resistance and a good, inexpensive manufacturability which predestines the use of ceramic materials.
