Description

Kolben mit Schutzring für Brennkraftmaschinen Den Gegenstand der Erfindung bildet die Verbesserung und weitere Ausgestaltung des Z> ZD in dem Patent 698-coi beschriebenen Kolbens für Brennk-raftmaschinen. Bei diesem ist der Kolbenboden von einem Schutzring umgeben, der nicht nur die führende Kolbenkante vor einer Beschädigung bzw. Zerstörung durch Korrosion scliüt7t, sondern auch das Zerstören des Olfilms verhindert und einen dauernden ölumlauf vor der führenden Kolbenkante und im Kolbenschutzring ermöglicht. Hierbei wird zweckmäßig der Schutzring durch einen an sich bekannten Federring in dauernder Berührung mit der führenden Kolbenkante gehalten, so daß er unbeweglich am Kolbenkopf festsitzt. Gemäß vorliegender Verbesserung besteht der Federring aus zwei Halbringen., wodurch erreicht wird, daß sich der Ring ohne Verformung leicht in die Ringnut des Kolbenkopfes einbringen läßt. Ferner über,-reifen Deckscheiben die Federringteile auch am hinteren Ende hakenartig und halten damit die Federringteile in festem Verband. Schließlich sind die Deckscheiben mit den Federringteilen derart verbunden, daß sie nur eine Verschiebung in senkrechter Richtung zueinander, dem Federdruck entsprechend, ausführen können.Flask equipped with a guard ring for internal combustion engines The object of the invention to improve and further design forms of the Z> ZD in the patent 698 coi described piston for internal combustion engines. In this case, the piston crown is surrounded by a protective ring, which not only protects the leading edge of the piston from damage or destruction by corrosion, but also prevents the oil film from being destroyed and enables constant oil circulation in front of the leading edge of the piston and in the protective ring. In this case, the protective ring is expediently kept in permanent contact with the leading edge of the piston by a spring ring known per se, so that it is immovably fixed on the piston head. According to the present improvement, the spring ring consists of two half-rings, which means that the ring can easily be inserted into the ring groove of the piston head without deformation. Furthermore, cover disks rip the spring ring parts like a hook at the rear end and thus keep the spring ring parts in a tight bond. Finally, the cover disks are connected to the spring ring parts in such a way that they can only move in a perpendicular direction to one another, in accordance with the spring pressure.

In der Zeichnung ist der verbesserte Kolben in einer beispielsweisen Ausführungsform veranschaulicht, und zwar zeigen: Abb. i einen Längsschnitt durch den Kolbenkopf und den Federring, Abb. 2 eine Draufsicht auf die Federringteile und Abb.3 einen Teil eines Federringes in Seitenansicht im Schnitt.In the drawing, the improved piston is in one example Embodiment illustrated, namely show: Fig. I a longitudinal section through the piston head and the spring ring, Fig. 2 is a plan view of the spring ring parts and Fig. 3 shows a part of a spring washer in a side view in section.

Gemäß der Verbesserung besteht der Federring aus zwei Halbringenp, die in bekannter Weise wellenförmig ausgebildet sind. Es wird durch die Teilung des Ringes der Vorteil erreicht, daß der Federring beim Einbringen in die Ringnut des Kolbenkopfes nicht auseinandergezogen zu werden braucht; auch kann er breiter als ein gewöhnlicher Kolbenring ausgeführt werden.According to the improvement, the spring ring consists of two half-rings, which are wave-shaped in a known manner. It is by division of the ring has the advantage that the spring ring when inserted into the ring groove the piston head does not need to be pulled apart; it can also be wider be designed as an ordinary piston ring.

jeder Federringteil ist durch zwei Scheiben r -, r' abgedeckt, wodurch die Wellen der Federn ausgeglichen werden. Während die Scheiben r, r' an der Außenseite nach vorn abgerundet sind (Abb. i), damit sich der Schutzring g leicht über den Federring schieben läßt, sind die Scheiben an der Innenseite zu rechtwinkligen Absätzen a ausgebildet, wodurch das Herausschieben der Ringteile aus dem Käfig r, r' nach einwärts verhindert wird.each spring ring part is covered by two washers r -, r ', whereby the waves of the springs are balanced. While the washers r, r ' are rounded towards the front on the outside (Fig. I), so that the protective ring g can easily be pushed over the spring ring, the washers on the inside are formed into right-angled shoulders a , which means that the ring parts can be pushed out the cage r, r 'is prevented from moving inwards.

jeder Halbring kann schließlich mit den Scheiben r, r' durch an der einen Scheibe befestigte Stifte t, die in an der anderen Scheibe befestigte Hülsens eingreifen, verbunden sein. E s wird hierdurch eine Gegeneinanderverschiebung der Scheiben und der Halbringe verhindert, jedoch eine senkrechte Verschiebung der Scheiben zu den Halbringen bei dem Aufschieben des Schutzringesg auf den Federring ermöglicht.each half-ring can finally be connected to the disks r, r ' by pins t attached to one disk which engage in sleeves attached to the other disk. E s is hereby prevents displacement against each of the discs and the half-rings, however, allows a vertical displacement of the discs to the half-rings when sliding the Schutzringesg on the spring ring.
