Description

Brennkraf tkolbenmaschine, deren Kolben fest mit einer am feststehenden Gehäuse gelagerten Schwinge eines Kreuzkurbelgetriebes verbunden sind Die Erfindung betrifft eine Brennkraftkolbenmaschine, bei der die Gaskräfte über einen Kolben und ein . Kreuzkurbelgetriebe auf die Kurbelwelle übertragen werden, und bei der der Kolben keine Berührung mit der inneren Zylinderwand oder einer auf dieser haftenden Schmiermittelschicht aufweist.Internal combustion piston machine, the piston of which is fixed to a stationary Housing mounted rocker arm of a cross-crank mechanism are connected to the invention relates to an internal combustion piston engine in which the gas forces are transmitted via a piston and a . Cross crank gear to be transmitted to the crankshaft, and at the the piston does not come into contact with the inner cylinder wall or anything adhering to it Has lubricant layer.

Brennkraftkolbenmaschinen mit einer Kraftübertragung mittels eines Kreuzkurbelgetriebes sind bereits bekannt, unter anderem auch durch die schweizerische Patentschrift 41658.Internal combustion piston machines with a power transmission by means of a Cross crank gears are already known, including the Swiss Patent 41658.

Ein Nachteil bei dieser Ausführung ist die erforderliche Schmierung der inneren Zylinderwand, die als Gleitfläche für den Kolben dient, wodurch bei Drehzahlsteigerung die Reibungsverluste durch die Schmiermittelschicht steigen; ferner wird ein relativ langer und damit schwerer Kolben zur Abdichtung gegen den Raum niederen Druckes benötigt.A disadvantage of this design is the need for lubrication the inner cylinder wall, which serves as a sliding surface for the piston, whereby at Increase in speed the friction losses increase through the lubricant layer; Furthermore, a relatively long and therefore heavy piston is used to seal against the Low pressure space required.

Zur Abdichtung gegen den Raum niederen Druckes sind bei Brennkraftkolbenmaschinen außerdem Kolbenringe in Gebrauch, die aber auch bei Drehzahl-und Drucksteigerung die Reibungsverluste durch die Schmiermittelschicht steigern, auf der sie gleiten und gegen die sie durch den Gasdruck gepreßt werden. Der dadurch verursachte Dünnfilmverschleiß muß durch sorgfältige Bearbeitung von Zylinder- und Kolbenwand gemildert werden.Internal combustion piston engines are used to seal against the space of low pressure also piston rings in use, but also when the engine speed and pressure increase increase the friction losses due to the lubricant layer on which they slide and against which they are pressed by the gas pressure. The resulting thin film wear must be softened by careful machining of the cylinder and piston walls.

Bekannt ist es auch, bei solchen Brennkraftkolbenmaschinen die Reibungsverluste bei Drehzahl- und Drucksteigerung dadurch zu verringern, daß der Kolben nicht auf einer Schmiermittelschicht der inneren Zylinderwand gleitet, sondern fest mit einer in größtmöglicher Nähe des mit einem becherförmig ausgebildeten Kopf versehenen Kolbens am feststehenden Gehäuse längs schiebbar gelagerten Schwinge eines Kreuzkurbelgetriebes verbunden ist und auf diese Weise mit der Zylinderwand einen Ringspalt bildet (Fig.1).It is also known that the friction losses in such internal combustion piston machines to reduce the increase in speed and pressure, that the piston does not open a lubricant layer of the inner cylinder wall slides, but firmly with a as close as possible to the cup-shaped head Piston on the fixed housing longitudinally slidably mounted rocker of a cross-crank gear is connected and in this way forms an annular gap with the cylinder wall (Fig. 1).

Der Erfindung liegt nun die Aufgabe zugrunde, bei einer derartigen Brennkraftkolbenmaschine den Verlust, der durch die Strömung in dem Ringspalt zwischen Kolben- und Zylinderwand entsteht, zu verringern und eine Leistungssteigerung zu erzielen.The invention is based on the object in such a Internal combustion piston machine the loss caused by the flow in the annular gap between Piston and cylinder wall is created to decrease and an increase in performance achieve.

Gelöst wurde diese Aufgabe gemäß der Erfindung dadurch, daß mittels einer Schneidenbildung am becherförmigen Kolbenrand, und zwar entsprechend der »Bordaschen Mündung«, der Verluststrom durch den eine konstante Breite aufweisenden Ringspalt zwischen Kolben- und Zylinderwand durch die dadurch erreichte Erzeugung einer verstärkten Kontraktion verringert wird (Fig.2). Dadurch ergibt sich ferner ein wesentlich kürzerer und damit leichterer Kolben. Damit wird der innere Wirkungsgrad besser, und es ist eine wirtschaftlich vertretbare Drehzahl-und Drucksteigerung und damit eine Steigerung des Gesamtwirkungsgrades der Brennkraftkolbenmaschine möglich.This object was achieved according to the invention in that by means of a cutting edge formation on the cup-shaped piston edge, in accordance with the »Bordaschers Muzzle «, the leakage current through the annular gap, which has a constant width between the piston and cylinder wall through the generation of a reinforced Contraction is decreased (Fig. 2). This also results in a much shorter one and thus a lighter piston. With that, the internal efficiency gets better, and it is an economically justifiable increase in speed and pressure and thus an increase the overall efficiency of the internal combustion piston engine is possible.
