 maschine ; denn wenn es erforderlich wäre, den Auspuff zeitweise abzustellen, dann würde eine zeitweise Kompression des verbauchten Druckmittels   statffinden,   bevor die abermalige Freigabe erfolgt, wodurch ein Gegendruck und eine Hemmung des Laufes verursacht werden würde. 



   Um Verluste durch Undichtwerden der Drehschieber zu vermeiden, sind diese ebenso wie die Aussenflächen der Kolbenflügel in folgender Weise ausgeführt. Die Leitlinien der 
 EMI2.1 
 halbmesser 23 (Fig. 6) dem Halbmesser   24   der inneren Zylinderfläche des kreisenden Gehäuses 5 gleich ist. Die Breite der Eintrittsöffnungen 27 der Ausnehmung 9 der Drehschieber   8, 81, 82   für den Kolbenflügel entspricht der Querschnittsbreite 28 der   Kolbenflügel.   



  Durch diese Bemessung wird ein dampfdichter Abschluss des Arbeitsraumes erzielt. 



   Die Drehschieber werden vorteilhaft in der aus Fig. 7 ersichtlichen Weise abgedichtet. 



  In der Ausnehmung 9 ist eine Nut 29 vorgesehen, die von einem Ende in der Wand der Ausnehmung bis nahe zum entgegengesetzten Ende reicht und mit einer Packung versehen ist. Die Drehschieber werden mittels auf ihren Spindeln 31 angeordneten Zahnrädern 30 von einem Zahnkranz 32 angetrieben. Kanäle 33 für Schmiermittel sind auch vorgesehen. 



   Das Treibmittel tritt durch die Hohlwelle 2 in die Trommel 1 ein und wird nach-

   19, 20   und 21 und durch den Auspuffstutzen 22   ausströmen.   



   Die Kanäle sind zweckmässig in der Weise angeordnet, dass ein Arbeitshub zwischen je zwei Kolbenflügel nacheinander sowie der Auspuff der Abgase des vorhergehenden Arbeitshubes stattfinden. Da drei Drehschieber und vier Kolbenflügel vorhanden sind, finden zwölf Kraftstösse während einer Umdrehung des kreisenden Gehäuses 5 statt. Man kann diese Zahl innerhalb gewisser Grenzen durch Vermehrung der Zahl der Drehschieber und Kolben-

   PATENT-ANSPRÜCHE : i. Kraftmaschine mit kreisendem, mit Kolbenflügeln versehenem Gehäuse und einer in diesem feststehenden Trommel, zwischen welchen Teilen ein ringförmiger, von den Kolbenflügeln des Gehäuses und von in der Trommel gelagerten Drehschiebern unterteilter Arbeitsraum gebildet wird, dadurch gekennzeichnet, dass das der Trommel (1) durch eine konzentrisch zur Drehachse liegende Hohlwelle   (2)   zugeführte Treibmittel durch zu beiden Seiten des Trommelumfanges, also gegenüberliegend, angeordnete Kanäle (11, 13) in den Expansionsraum   (17)   gelangt, der ständig mit der Aussenluft in Verbindung steht, so dass das expandierte Druckmittel ständig austreten kann.

 machine; because if it were necessary to temporarily shut off the exhaust, then a temporary compression of the used pressure medium would take place before the renewed release takes place, whereby a counter pressure and an inhibition of the run would be caused.



   In order to avoid losses due to leaks in the rotary valve, they are designed in the following manner, as are the outer surfaces of the piston vanes. The guidelines of the
 EMI2.1
 radius 23 (Fig. 6) the radius 24 of the inner cylindrical surface of the rotating housing 5 is equal. The width of the inlet openings 27 of the recess 9 of the rotary valve 8, 81, 82 for the piston wing corresponds to the cross-sectional width 28 of the piston wing.



  A vapor-tight closure of the work area is achieved through this dimensioning.



   The rotary slide valves are advantageously sealed in the manner shown in FIG.



  In the recess 9, a groove 29 is provided which extends from one end in the wall of the recess to near the opposite end and is provided with a packing. The rotary slides are driven by a toothed ring 32 by means of gear wheels 30 arranged on their spindles 31. Channels 33 for lubricant are also provided.



   The propellant enters the drum 1 through the hollow shaft 2 and is

   19, 20 and 21 and flow out through the exhaust port 22.



   The channels are expediently arranged in such a way that one working stroke between each two piston vanes takes place one after the other, as well as the exhaust of the exhaust gases from the previous working stroke. Since there are three rotary slides and four piston vanes, twelve force impulses take place during one revolution of the rotating housing 5. You can increase this number within certain limits by increasing the number of rotary valves and piston

Reversing the machine can be achieved by swapping the inlets and outlets.



   PATENT CLAIMS: i. Power machine with a rotating housing provided with piston vanes and a drum stationary in this, between which parts an annular working space is formed, which is divided by the piston vanes of the housing and rotary valves mounted in the drum, characterized in that the drum (1) is formed by a Propellant supplied concentrically to the axis of rotation of the hollow shaft (2) passes through channels (11, 13) arranged on both sides of the drum circumference, i.e. opposite one another, into the expansion space (17), which is constantly in connection with the outside air, so that the expanded pressure medium is constantly can escape.
