Description
Drehkolbenbrennkraftmaschine Die Erfindung betrifft eine Drehkolbenmaschine, insbesondere Drehkolbenbrennkraftmaschine, bei welcher in einem umlaufenden hohlen Gehäuse Kolben schrittweise umlaufen.Rotary piston internal combustion engine The invention relates to a rotary piston engine, in particular rotary piston internal combustion engine, in which in a circumferential hollow Rotate the housing piston step by step.
Bei den bisher bekanntgewordenen Maschinen dieser Artentstanden Betriebsschwierigkeiten dadurch, @daß die in den Gasdruckkammern auftretende große Wärme sich auf die Kolben und die sie umgebenden Gehäuseteile übertrug und hierbei Ausdehnungen des Materials und Verspannungen hervorriefen, welche die Ursache dafür wurden, daß .die Kolben und ihre Triebwerksteile sich nach kurzer Betriebsdauer festbrannten.Operating difficulties arose with the machines of this type that have become known up to now in that the great heat occurring in the gas pressure chambers is applied to the pistons and transferred the housing parts surrounding them and thereby expansions of the material and caused tension, which was the reason that .the pistons and their engine parts burned down after a short period of operation.
Erfindungsgemäß soll daher versucht werden, -die Kolbenlaufbahn möglichst frei von allen sie umgebenden Maschinenteilen zu machen und den Aufbau der Maschine so zu gestalten, daß die Wärme in den Gaskammern ohne Schaden für diese Maschinenteile an ein Kühlmittel abgeleitet werden ka=.According to the invention, an attempt should therefore be made, as far as possible, to keep the piston running track free of all surrounding machine parts and the structure of the machine to design so that the heat in the gas chambers without damage to these machine parts can be derived from a coolant ka =.
Eine Ausführungsform dieses Gedankens zeigen: Fig. i im Längsschnitt, Fig.2 im Querschnitt, während die Fig.3 im Längsschnitt eine weitere Ausführungsform darstellt.An embodiment of this idea shows: Fig. I in longitudinal section, FIG. 2 in cross section, while FIG. 3 shows a further embodiment in longitudinal section represents.
A ist das Maschinengehäuse, welches mit seiner einen Nabe auf der Welle Ws festsitzt und sich mit seiner anderen Nabe auf der Welle W, dreht. Die Kolbenlaufbahn ist zu einem ringförmigen Hohlkörper ausgebildet, welcher in zwei Hälftena, und b1. geteilt ist. Die Hälfte a1 ist durch einen Steg mit dem Gehäuse A und die Hälfte b1 durch einen Steg mit der Welle W, verbunden. Die Kolben werden von der Hälfte a1, die Kolben b von der Hälfte b1 getragen. Die Kolben a und b führen gegeneinander eine Relativbewegung aus. Fig. i zeigt eine Ausführung, bei welcher die Trennebene zwischen den Hälften a, und b1 axial, Fig.3 eine Ausführung, bei welcher die Trennebene radial verläuft. Die Trennebene zwischen den Hälften a, und b1 kann auch außerhalb der Kolhenmitte liegen. Diese Trennflächen müssen so gegeneinander abgedichtet werden, daß ,aus den Gasdruckkammern kein Druck entweichen kann. Der Querschnitt der Kolben kann entweder, wie in Fig. i und Fig. 3 gezeigt, rund sein oder, wie in Fig. i a und Fig. 3 a gezeigt, andere Form haben.A is the machine housing, which with its one hub on the Shaft Ws is stuck and rotates with its other hub on the shaft W,. the Piston raceway is formed into an annular hollow body, which in two Halves, and b1. is divided. Half a1 is through a web with the housing A and half b1 are connected to the shaft W by a web. The pistons will carried by half a1, the pistons b carried by half b1. Guide pistons a and b a relative movement against each other. Fig. I shows an embodiment in which the parting plane between the halves a, and b1 axially, Figure 3 an embodiment, at which the parting plane runs radially. The parting line between the halves a, and b1 can also lie outside the center of the piston. These interfaces must be so against each other be sealed so that no pressure can escape from the gas pressure chambers. Of the Cross-section of the pistons can either be round, as shown in FIGS. 1 and 3 or, as shown in Fig. 1a and Fig. 3a, have a different shape.
Die rechts und links von den Stegen gebildeten Hohlräume Al. -und B1 können räumlich groß gestaltet werden. Sie umgeben die Kolbenlaufbahn vollständig, so daß diese von einem die Hohlräume anfüllenden Kühlmittel ungehindert umspült werden.The cavities Al formed to the right and left of the webs. -and B1 can be designed spatially large. They completely surround the piston raceway, so that a coolant filling the cavities flows around them unhindered will.
