Description
Kolben mit entlasteten Kolbenringen Bei den bekannten Kolbenringdichtungen an Explosionsmotoren dringt der Kompressions-und Arbeitsdruck zwischen Ring und Kolbenringnut sowie durch den Zungenschnitt des Ringes in die Kolbenringnut hinter den Kolbenring und preßt diesen dann mit einem den der natürlichen Spannung entsprechenden weit übersteigenden Druck an die Zylinderwandung an. Infolgedessen ist die Abnutzung des ersten Ringes außen und seitlich größer als bei den folgenden Ringen. Auch wird die erste Kolbenringnut schneller ausgeschlagen, wodurch dann die folgeriden Ringe in abnehmendem Maße gleichfalls in Mitleidenschaft gezogen werden. Aus diesem Grunde ist -die Laufzeit eines Kolbens oft nur sehr kurz, auch müssen die Zylinderbohrungen, welche an den dem hohen Druck ausgesetzten Stellen stärker abgenutzt werden, häufig ausgeschliffen werden.Pistons with relieved piston rings In the known piston ring seals on explosion engines, the compression and working pressure penetrates between the ring and the piston ring groove and through the tongue cut of the ring into the piston ring groove behind the piston ring and then presses it against the cylinder wall with a pressure that is far greater than the natural tension . As a result, the wear on the first ring is greater on the outside and on the sides than on the following rings. The first piston ring groove is also knocked out more quickly, as a result of which the consequential rings are also affected to a decreasing extent. The term of a piston often very short, also have the cylinder bores, which are worn more on the subject to the high pressure points are often ground out - for this reason.
Gemäß der Erfindung soll dieser Übelstand dadurch beseitigt werden, daß der erste Ring mittels Federdruck an die abzudichtende Seite der Ringnut derart angepreßt wird, daß ein Durchströmen der Gase an dieser Stelle verhindert wird. Die Kolbenringschlitze an den Zungen werden in bekannter Weise durch innere Ringe abgedichtet.According to the invention, this drawback is to be eliminated by that the first ring by means of spring pressure on the side of the ring groove to be sealed in such a way is pressed so that a flow of the gases is prevented at this point. The piston ring slots on the tongues are made in a known manner by inner rings sealed.
In Abb. x werden die Kolbenringe a mittels eines zweiteiligen Tragringes b durch die Feder c an die. Kolbenringnut bei d angepreßt und dichten hier ab. Der Tragring b wird durch einen Ansatz e, welcher hinter den Kolbenring _ greift, gegen eine Verschiebung nach außen gesichert. Die Schrauben f, die auch zur Einstellung des Tragringes dienen, sind durch Zapfen g in diesem geführt und werden durch die Muttern h in ihrer Stellung gehalten. Durch die Muttern i werden die Federn c gespannt. Die Federringe l dichten die Kolbenringschlitze nach innen ab.In Fig. X, the piston rings are a by means of a two-part support ring b by the spring c to the. Piston ring groove pressed on at d and seal here. Of the Support ring b is countered by a shoulder e, which engages behind the piston ring an outward shift secured. The screws f that are also used to adjust serve the support ring are guided by pin g in this and are through the Nuts h held in place. The springs c are tensioned by the nuts i. The spring washers l seal the piston ring slots from the inside.
Abb. 2 zeigt den Kolben von unten gesehen.Fig. 2 shows the piston seen from below.
