Description
Bisher hat man Kolben mit Kolbenringen aus Metall oder auch mit Dichtungen aus Leder, Gummi od. dgl. verwendet.So far, pistons with piston rings made of metal or with seals have been used Made of leather, rubber or the like. Used.
Die Kolbenringe passen sich der Zylinderwandung infolge ihrer Beweglichkeit und Federung zwar gut an. Sie weisen aber den Nachteil eines hohen Verschleißes auf. Die bisher verwendeten Dichtungsmanschetten werden leicht einseitig abgenutzt, z. B. bei waagerechtem Zylinder und beim Nachziehen der Stopfbuchse, wodurch die Lage der Kolbenstange verändert wird. Gegenüber den Kolbenringen weisen die Manschetten andererseits eine bessere Dichtigkeit auf.The piston rings adapt to the cylinder wall due to their mobility and suspension is good. But they have the disadvantage of high wear on. The previously used sealing sleeves are easily worn on one side, z. B. with a horizontal cylinder and when tightening the stuffing box, whereby the The position of the piston rod is changed. Opposite the piston rings are the sleeves on the other hand, a better tightness.
Erfindungsgemäß wird nun eine Kombination der beiden vorbeschriebenen bekannten Dichtungsmöglichkeiten vorgeschlagen, indem der Kolben mit Kolbenringen ausgerüstet ist, die ihrerseits als Träger von Dichtungsmanschetten ausgebildet sind.According to the invention, a combination of the two is now described above known sealing options proposed by the piston with piston rings is equipped, which in turn is designed as a carrier of sealing sleeves are.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung.The drawing shows an embodiment of the invention.
Der Kolben 24 hat zwei Nuten, in denen Kolbenringe 25, 26 mit dem üblichen Spiel liegen.The piston 24 has two grooves in which piston rings 25, 26 with the usual game lie.
Diese Kolbenringe 25, 26 sind noch mit Dichtungsmanschetten 27, 28 aus Leder oder anderem geeigneten nachgiebigen Werkstoff versehen.These piston rings 25, 26 are also provided with sealing collars 27, 28 made of leather or other suitable flexible material.
Durch die Vereinigung der Kolbenringe 25, 26 mit den, Dichtungsmanschetten 27, 28 werden die Vorteile beider Teile erzielt, ohne daß die erwähnten Nachteile auftreten.By uniting the piston rings 25, 26 with the sealing sleeves 27, 28, the advantages of both parts are achieved without the disadvantages mentioned appear.
In den Kolbennuten können sich die Kolbenringe 25, 26 frei bewegen, so daß die an den Kolbenringen befestigten, z. B. eingeklemmten Manschetten 27, 28 ans Leder od. dgl. sich mit den Kolbenringen 25, 26 bewegen und sich unabhängig von der Lage der Kolbenstange 24° der Zylinderwandung 17 anpassen können.In the piston grooves, the piston rings 25, 26 can move freely, so that the attached to the piston rings, for. B. clamped cuffs 27, 28 od to the leather. Like. Move with the piston rings 25, 26 and the cylinder 17 can adjust independently of the position of the piston rod 24 °.
Selbstverständlich kann auch ein beweglicher Kolbenring 25, 26 gleichzeitig zwei oder mehrere Manschetten aufnehmen.Of course, a movable piston ring 25, 26 can also be used at the same time accommodate two or more cuffs.
