Description

Brennkraft-Drehkolbenmaschinen mit exzentrisch laufenden kreisrunden Drehkolben und federbelasteten Widerlagerschiebern sind bekannt sowie verschiedene zwangsläufig gesteuerte Widerlagerschieber für Kolben in mittig laufenden Zylindern.Internal combustion rotary piston machines with eccentric running circular Rotary pistons and spring-loaded abutment slides are known and various Inevitably controlled abutment slide for pistons in centrally running cylinders.

Die Erfindung bezweckt, Maßnahmen zur möglichst vollen Abdichtung bei Brennkraft-Drehkolbenmaschinen mit hoher Umdrehungszahl zu schaffen. Zwischen den Widerlagerschiebern und den exentrisch umlaufenden Kolben sind an sich bekannte Dichtschwimmer, welche sich den Kurven anpassen, eingebaut. Da durch frei laufende Widerlagerschieber bei hoher Umdrehungszahl Beschleunigungskräfte auftreten, so werden diese durch Preßluft auf die exzentrischen Drehkolben gedrückt. Die Preßluft wird durch einen kleinen im Widerlagerschieber eingebauten Kolben, welcher von diesem mitgenommen und durch den exzentrisch laufendenKolben zurückgedrückt wird, erzeugt. Die exzentrisch laufenden kreisrunden Kolben sowohl für den Pumpen- als auch für den Arbeitszylinder sind an beiden Seiten mit Führungsscheiben verbunden, auf welchen Kolbenringe angebracht sind, welche eine gute seitliche Abdichtung nach innen und außen erzeugen sollen. Die weitere Abdichtung zwischen den exzentrisch laufenden Kolben und der Zylinderwand erfolgt durch Schleifstücke, welche beim Lauf gegen dieZylinderwand gedrückt werden.The aim of the invention is to provide measures for the fullest possible seal to create in internal combustion engine rotary piston machines with a high number of revolutions. Between the abutment slide and the eccentrically rotating piston are known per se Built-in sealed floats, which adapt to the curves. Because by free running Abutment slide acceleration forces occur at high speeds, so these are pressed onto the eccentric rotary lobes by compressed air. The compressed air is driven by a small piston built into the abutment slide, which is driven by it is taken and pushed back by the eccentric piston. The eccentrically running circular pistons for both the pump and the the working cylinders are connected on both sides with guide washers on which Piston rings are attached, which provide a good internal and lateral seal should generate outside. The further sealing between the eccentric running Piston and the cylinder wall is made by contact strips, which run against the cylinder wall are pressed.

Bild i veranschaulicht einen Längsschnitt der Maschine; Bild 2 zeigt einen Querschnitt durch den Arbeitszylinder; Bild 3 gibt einen Querschnitt durch den Pumpenzylinder, Bild 4 stellt die Drehkolbenwelle in Längsansicht und Bild 5 in Seitenansicht dar. Bild 6 zeigt die Abdichtung mittels eines Widerlagerschiebers in der inneren Stellung, Bild 7 eines Zangenklemmhebels.The drawing shows an example of a schematic embodiment of the invention shown. Figure i illustrates a longitudinal section of the machine; Figure 2 shows a cross section through the working cylinder; Picture 3 gives a cross section through the pump cylinder, Figure 4 represents the rotary piston shaft in a longitudinal view and Figure 5 shows a side view. Figure 6 shows the seal by means of an abutment slide in the inner position, Figure 7, of a pliers clamping lever.

Der: Expansionsraum 15 wird rückwärts durch Widerlagerschiebervon beliebigerForm abgesperrt. Die frei laufenden Widerlagerschieber 16 werden zwangsläufig durch komprimierte Luft auf die Dichtschwimmer 17 und diese auf die Drehkolben 2 und 3 gedrückt. In dem Widerlagerschiebergehäuse i9 ist ein Stufenkolben 20 eingebaut, welcher von Widerlagerschieber 16 betätigt wird. Durch die Stufe 21 wird so lange Luft in das Widerlagerschiebergehäuse i9 gefördert, bis die erforderliche Kompression erreicht wird, um den Widerlagerschieber 16 auf den Dichtschwimmer 17 zu drücken. Der erforderliche Druck im WiderlagVschiebergehäuse.ig wird durch kleine Sicherheitsorgane reguliert. Die rückwärtige Abdichtung im Expansionsraum 15 kann auch durch Zangenklemmhebel 24 erfolgen. Weiter erhalten die Drehkolben 2 und 3 Abdichtungsschleifstücke, welche beim Lauf der Drehkolben 2 und 3 gegen die Zylinderwand 4 und 5 gedrückt werden. Desgleichen erhalten die Drehkolben 2 und 3 an beiden Seiten für eine bessere Abdichtung Führungsscheiben 6 und 7.The: expansion space 15 is backwards by abutment slide from of any shape. The free running abutment slide 16 are inevitable by compressed air on the sealing floats 17 and these on the rotary lobes 2 and 3 pressed. A stepped piston 20 is installed in the abutment slide housing i9, which is actuated by the abutment slide 16. Level 21 becomes so long Air is pumped into the abutment valve housing i9 until the required compression is reached in order to press the abutment slide 16 onto the sealing float 17. The required pressure in the abutment valve housing is controlled by small safety devices regulated. The rear seal in the expansion space 15 can also be achieved by means of pliers clamping levers 24 take place. Rotary pistons 2 and 3 also receive sealing grinding pieces, which while the rotary pistons 2 and 3 are pressed against the cylinder wall 4 and 5. Likewise, the rotary lobes 2 and 3 are given on both sides for a better seal Guide washers 6 and 7.
