Description

Kugel mit Kräften, die durch Pfeile angedeutet sind. Dank der Verbindung der Räume 7 und 9 wird ein großer Teil der Kraft über die im Raum 7 eingeschlossene Flüssigkeit unmittelbar auf die Kugel übertragen. Der Kontaktdruck zwischen der Kugel 5 und dem Sitz 6 bleibt deshalb so niedrig, daß die Kugel leicht im Sitz 6 rotieren kann, dieser gleichmäßig abgenutzt wird und bei der Rotation der Kugel kein Pressen entsteht. Durch geeignete Ausbildung des schalenförmigen Raumes im Kolben ? kann man dem ringförmigen Wandteil mit dem Siez 6 eine solche Dicke geben, daß er sich auf Grund des Druckes im Raum 7 in Abhängigkeit vom Druck im Zylinder so ausdehnt, daß das Spiel zwischen ihm und der Zy-Sphere with forces indicated by arrows. Thanks to the connection between rooms 7 and 9, a large part of the force via the one trapped in room 7 Transfer liquid directly to the ball. The contact pressure between the ball 5 and the seat 6 therefore remains so low that the ball can rotate easily in the seat 6, this evenly is worn and there is no compression as the ball rotates. Appropriate training of the bowl-shaped space in the flask? you can the annular wall part with the Siez 6 such Thickness give that he is due to the pressure in space 7 depending on the pressure in the cylinder so extends that the game between him and the cy-

linderwand mit steigendem Diuck abnimmt. Hierdurch kann eine bessere Dichtung und somit ein besserer volumetrischer Wirkungsgrad erhalten werden. Die Erfindung ist nicht auf die in den Figuren gezeigte Ausführungsform begrenzt, sondern mehrere Abänderungen sind im Rahmen der Patentansprüche denkbar. So kann z.B. die Wand des Kolbens3 am nächsten der Kugel 4 schwach konisch und mit einem Kegelwinkel ausgeführt sein, der von der größten Schrägstellung des Kolbens bestimmt ist, die vorkommen kann. Der Durchmesser des Sitzes kann dann größer gemacht und der größere Teil der Kraft zwischen Kugel und Kolben kann dadurch hydraulisch ausgeglichen werden.linderwand decreases with increasing pressure. Through this a better seal and thus a better volumetric efficiency can be obtained. The invention is not limited to the embodiment shown in the figures, but several Changes are conceivable within the scope of the claims. For example, the wall of the piston 3 on the next to the ball 4 be slightly conical and designed with a cone angle that of the largest Inclination of the piston is determined that can occur. The diameter of the seat can then made larger and the greater part of the force between the ball and piston can thereby be hydraulic be balanced.
