Description

Abdichtung für Brennkraftmaschinen mit umlaufendem oder um seine Mittelachse schwingendem Schieber in Gestalt einer Kugel . Die Erfindung betrifft eine Abdichtung für Brennkraftmaschinen mit umlaufendem oder um seine Mittelachse schwingendem Schieber in Gestalt einer Kugel für den Ein- und Auslaß der Gase und mit einem federnd an die Kugel gepreßten umlaufenden Ring zur Abdichtung des Zylinders gegenüber demSchieber.Seal for internal combustion engines with a circumferential or around its central axis swinging slide in the shape of a ball. The invention relates to a seal for internal combustion engines with a rotating slide or a slide swinging around its central axis in the form of a ball for the inlet and outlet of the gases and with a resilient one the ball pressed circumferential ring to seal the cylinder against the slide.

Es ist bekannt, solche Dichtungsringe durch die _ Bewegung der hindurchgeleiteten Gase oder durch besondere Antriebsteile, wie Zahnräder, in Umlauf zu versetzen. Das Anpressen des Ringes an die Kugel wird bei bekannten Ausführungen durch den im Zylinder herrschenden Druck mittels Federn, .durch Flüssigkeitsdruck und bei Umlaufmotoren durch Fliehkraft bewirkt.It is known that such sealing rings by the movement of the passed through To put gases or by special drive parts such as gears in circulation. The pressing of the ring against the ball is in known designs by the pressure prevailing in the cylinder by means of springs, by means of fluid pressure and at Rotary motors caused by centrifugal force.

Nach der Erfindung wird der Dichtungsring auf neuartige, besonders einfache und zuverlässige Weise in Umlauf versetzt. Zu diesem Zweck wird seine Achse schräg zur Achse des kugelförmigen Schiebers angeordnet, so daß er an der Abdichtungsstelle beim Umlauf der Kugel. an verschiedenen Stellen ungleich große Reibung erfährt. Auf diese Weise setzt sich der Schieber ohne zusätzliche Getriebeteile zuverlässig in die zur Erhaltung der gleichmäßigen Abdichtung erforderliche Bewegung.According to the invention, the sealing ring is novel, particularly easily and reliably put into circulation. For this purpose becomes its axis arranged obliquely to the axis of the spherical slide, so that it is at the sealing point while the ball revolves. experiences unequal friction at different points. In this way, the slide sits reliably without additional gear parts in the movement required to maintain the uniform seal.

Die Erfindung ist in den Abb. r und 2 beispielsweise dargestellt.The invention is shown in Figures r and 2, for example.

Abb: i zeigt die Steuerung im Schnitt durch die Achse des kugelförmigen Steuerschiebers; letzterer ist in Ansicht dargestellt. Es ist i der Kugelschieber mit der Antriebswelle 2, die durch ein Kreuzgelenk 3 mit der Antriebswelle eines benachbarten Zylinders verbunden sein kann. Die Kugel läuft in dem Steuerkopf d. um, der durch den Kanal 5 mit dem Verbrennungsraum 6 des Zylinders 7 in Verbindung steht. Der Dichtungsring 8 ist nach Art eines Stufenkolbens in dem rohrförmigen Teil s gelagert und durch Kolbenringe 9 abgedichtet. Dabei ist der rohrförmige Teil 5 mit dem Anschluß io für ein Druckmittel, durch welches das Anpressen bewirkt wird, versehen. Die Kolbenringe sind so bemessen, daß sich der Dichtungsring sehr leicht dreht, während er unter Reibung abdichtend auf die umlaufende Kugel i gepreßt wird. Die Achse des Dichtungsringes verläuft schräg zur Drehachse des Schiebers.Fig: i shows the control in section through the axis of the spherical Control slide; the latter is shown in view. It's i the ball valve with the drive shaft 2, which by a universal joint 3 with the drive shaft of a adjacent cylinder can be connected. The ball runs in the control head d. around, which through the channel 5 with the combustion chamber 6 of the cylinder 7 in connection stands. The sealing ring 8 is in the manner of a stepped piston in the tubular Part s stored and sealed by piston rings 9. Here is the tubular part 5 with the connection io for a pressure medium through which the pressing is effected, Mistake. The piston rings are dimensioned so that the sealing ring is very easy to move rotates while it is pressed sealingly against the rotating ball i under friction. The axis of the sealing ring runs obliquely to the axis of rotation of the slide.

Da ein Flächenteil des Dichtungsringes 8 im Bereich der durch gestrichelte Linien begrenzten Kugelzone i i Reibungen bei geringerer Bewegungsgeschwindigkeit erfährt als ein entsprechender Flächenteil im Bereich der Kugelzone 12, wird er Dichtungsring 8 durch die Kugel i bei ihrem Umlauf in langsame Umdrehungen versetzt, wodurch die Bildung von Ölkrusten u. dgl. zuverlässig vermieden und die Abdichtung auch bei langer Betriebsdauer gesichert wird.Since a surface part of the sealing ring 8 in the area of the dashed line Lines delimited spherical zone i i friction at lower speed of movement experiences as a corresponding surface part in the area of the spherical zone 12, it becomes Sealing ring 8 rotated slowly by the ball i as it rotates, whereby the formation of oil crusts and the like reliably avoided and the seal is secured even after a long period of operation.

Abb. 2 'zeigt, gleichfalls im Schnitt, eine Ausführung des Dichtungsringes,hei der das t Anpressen durch Gas- oder Flüssigkeitsdruck in Wegfall kommt. Der rohrförmige Teil des Zylinders 5 ist in dem mit 13 bezeichneten Bereich verjüngt ausgebildet, und die Kolbenringe g bewirken durch ihre Federung das Anpressen des Dichtungsringes 8 an die Kugel.Fig. 2 'shows, also in section, an embodiment of the sealing ring, hot the t pressing by gas or liquid pressure in omission comes. The tubular part of the cylinder 5 is in the area indicated by 13 tapered, and the piston rings g bring about the pressing due to their resilience of the sealing ring 8 to the ball.
