KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei Kolben von großem Durchmesser für Dampfmaschinen verhindert man ein einseitiges Einschleifen der Kolbenringe dadurch, daß man sie auf im Kolben drehbaren Ringen befestigt, die unter dem Einfluß eines Gesperres stehen. Die Ringe sollen sich beim Gang des Kolbens in einer Bewegungsrichtung gegen die Zylinderwand verdrehen, während sie in der entgegengesetzten Bewegungsrichtung durch das Gesperre an einer Rückdrehung verhindert werden. Den Gegenstand vorliegender Erfindung bildet eine Einrichtung , durch welche das Festbrennen der Kolbenringe bei Explosionskraftmaschinen, was besonders bei großen Maschinen sehr leicht eintritt, verhindert werden soll.In the case of pistons with a large diameter for steam engines, one-sided is prevented Grinding in the piston rings by attaching them to rings which are rotatable in the piston and which, under the influence of a Are locked. The rings should move in one direction of movement when the piston moves twist against the cylinder wall while moving in the opposite direction can be prevented by the locking mechanism from rotating backwards. The subject of the present invention is a device which causes the piston rings to stick in explosion engines, which is especially true in large machines occurs easily, should be prevented.
Als Verhinderungsmittel ist in diesem Falle ebenfalls eine Drehbewegung der Ringe zum Kolben vorgesehen.As a preventive means in this case is also a rotary movement of the rings to Piston provided.
Die Erzielung derselben erfolgt aber bei der vorliegenden Einrichtung zwangsweise.The achievement of the same is compulsory with the present device.
Dieselbe besteht im wesentlichen darin, daß in die Ringe Federn eingesetzt sind, die in Nuten der Zylinderwandung eingreifen. Die Nuten sind schräg zur Zylinderachse oder auch in Spirallinie geführt, so daß die Kolbenringe dann beim Hin- und Hergange des Kolbens eine seitliche Bewegung ausführen. Ein Festbrennen ist infolge dieser Bewegung nicht mehr zu fürchten.The same consists essentially in the fact that springs are inserted into the rings, which in Engage grooves in the cylinder wall. The grooves are oblique to the cylinder axis or also guided in a spiral line, so that the piston rings then when going back and forth of the Make a lateral movement of the piston. Burning is due to this movement no longer to fear.
Die Erfindung ist auf der Zeichnung veranschaulicht, und zwar inThe invention is illustrated in the drawing, namely in
Fig. ι im Querschnitt und inFig. Ι in cross section and in
Fig. 2 im Längsschnitt durch den Motorzylinder. Fig. 2 in longitudinal section through the engine cylinder.
In die Kolbenringe α sind Federn b oder Stifte eingesetzt, die unter dem Einfluß von Druckfedern c stehen. Diese letzteren verhindern, daß zwischen den Federn b und Nuten schädliche Zwischenräume und Undichtheiten entstehen. Die Federn b greifen in Nuten d der Zylinderwandung ein, die schräg oder spiralig zur Zylinderachse verlaufen. In the piston rings α springs b or pins are used, which are under the influence of compression springs c . These latter prevent harmful gaps and leaks from occurring between the tongues b and the grooves. The springs b engage in grooves d in the cylinder wall, which run obliquely or spirally to the cylinder axis.
