Description

Es ist bei Kolben für Brennkraftmaschinen bekannt, die Kolbenringnuten durch Kanäle mit dem Verbrennungsraum zu verbinden, um auf diese Weise unter Vermittlung des Betriebsdruckes die Kolbenringe an die Zylinderwandung anzudrücken. Die Erfindung geht von dem Gedanken aus, daß es nicht ratsam ist, die Kolbenringe als solche einem wechselnden Druck oder besser einer ständig wechselnden Belastung und Entlastung auszusetzen, sondern daß es vorteilhafter ist, einen möglichst gleichbleibenden Druck auf die Ringe einwirken zu lassen. Zu diesem Zweck ist nach der Erfindung in dem im Kolben befindlichen Verbindungskanal zwischen dem Verbrennungsraum und der Kolbenringnut ein Rückschlagventil eingebaut, durch dessen einstellbare Federkraft der auf die Rückseite der Kolbenringe wirkende Anpreßdruck in bestimmter Höhe festgelegt werden kann.It is known in pistons for internal combustion engines that the piston ring grooves are formed by channels to connect with the combustion chamber, in order in this way by means of the operating pressure, the piston rings to the cylinder wall to press. The invention is based on the idea that it is not It is advisable to keep the piston rings as such a changing pressure or better one constantly subject to changing stress and relief, but that it is more advantageous to let a constant pressure as possible act on the rings. To this Purpose is according to the invention in the connecting channel located in the piston between A check valve is built into the combustion chamber and the piston ring groove, through whose adjustable spring force the open the back of the piston rings acting contact pressure set at a certain level can be.

Auf der Zeichnung ist eine Ausführung gemäß der Erfindung veranschaulicht. Es zeigen:An embodiment according to the invention is illustrated in the drawing. It demonstrate:

Abb. ι eine Teilansicht von Kolben und Zylinder im Schnitt,Fig. Ι a partial view of the piston and cylinder in section,

Abb. 2 eine Aufsicht der Abb. 1. Der Kolben α ist gegen den Zylinder b durch Kolbenringe c abgedichtet. Die Ausnehmungen c', in welchen die Ringe c liegen, stehen mit einer Bohrungd durch Anschlüsse ei' in Verbindung. Eine senkrecht zu der Bohrung d stehende Bohrung e mündet in eine oben erweiterte Ausnehmung /. Diese ist derart erweitert, daß sie den Lagerkörper g für das Rückschlagventil aufnehmen kann. Das Ventil h ist durch eine Feder h' gegen den Körper g abgestützt, wobei die durchbrochene, in den Körper g lose geführte Scheibe i um die nötige Führung für das Ventil h besorgt ist. Die Durchbrechungen sind auf der Zeichnung mit i' bezeichnet.Fig. 2 is a top view of Fig. 1. The piston α is sealed against the cylinder b by piston rings c. The recesses c ' in which the rings c are located are connected to a bore d through connections ei'. A borehole e perpendicular to the borehole d opens into a recess / widened at the top. This is expanded so that it can accommodate the bearing body g for the check valve. The valve h is supported against the body g by a spring h ' , the perforated disk i loosely guided in the body g taking care of the necessary guidance for the valve h . The openings are marked i ' in the drawing.

Die das Gewinde erfassende Mutter k ist zu dem Zweck vorgesehen, die Feder bezüglich ihrer Spannung zu beeinflussen. The nut k engaging the thread is provided for the purpose of influencing the tension of the spring.
