Bei der anschließenden Bewegung der beiden Doppelkolbenplatten 1, 2 in Richtung der Seitenwände 15, 16 wird das zuvor in den Arbeitskammern AI, A2 angesaugte Fördermedium durch die Auslassventile 19a, 19b ausgesto¬ ßen und gleichzeitig wird Fördermedium über das Einlass- ventil 18c in die große Arbeitskammer A3 gesaugt. Auf diese Weise ist mit zwei zusammenwirkenden Doppelkolbenplatten 1, 2 und drei Arbeitskammern AI, A2 und A3 in ein und demselben Gehäuse 3 ein effektiver Förderbetrieb ge¬ währleistet. Das Maximalvolumen der beiden kleinen äuße- ren Arbeitskammern AI und A2 entspricht dem Maximalvolu¬ men der großen, inneren Arbeitskammer A3. Mit gleicherma- ßen hoher Effektivität kann die oben beschriebene Kolben¬ maschine auch als Verdichter oder als Expansionsmotor oder als Kombination von diesen betrieben werden. Beispielsweise kann die mittlere - große - Arbeitskammer A3 als Expansionsmotor arbeiten, während die beiden äußeren - kleinen - Arbeitskammern AI und A2 als Verdichter oder als Pumpe arbeiten und von dem Expansionsmotor angetrieben werden. Beim Einsatz der beschriebenen Kolbenpumpe als Verdichter könnten die innere Arbeitskammer A3 und eine äußere (linke) Arbeitskammer AI als erste Verdich¬ terstufe und die andere äußere Arbeitskammer A2 als zwei¬ te Verdichterstufe betrieben werden. The piston machine designed in this way can be operated as a compressor, as a pump or as a motor. For example, in the function of a pump in the inner large working chamber A3 (Figure 3) located between the two double piston plates 1, 2, previously sucked on the inlet valve 18c conveyed during Schwenkbewe ¬ tion of the double piston plates 1, 2 in the direction of the parting line X. As shown in FIG. 2 and 3 again ejected from the working chamber A3. During this pivotal movement (ejection), at the same time via the inlet valves 18a, 18b, a fluid is sucked into the two outer (small), each between the double piston plates 1 and 2 and the side walls 15 and 16 forming working chambers AI and A2. During the subsequent motion of the two double piston plates 1, 2 in the direction of the side walls 15, 16 is previously in the working chambers Al, A2 sucked conveying medium large in by the exhaust valves 19a, 19b ausgesto ¬ SEN, and is simultaneously pumped through the inlet valve 18c Working chamber A3 sucked. In this way is ensured ge ¬ with two cooperating double piston plates 1, 2 and three working chambers Al, A2 and A3 in the same housing 3, an effective feed operation. The maximum volume of the two small outer working chambers AI and A2 corresponds to the maximum volume of the large inner working chamber A3. With equal SEN high efficiency can also be operated as a compressor or as an expansion engine or a combination of these, the above-described piston ¬ machine. For example, the medium-large working chamber A3 can operate as an expansion engine, while the two outer-small working chambers AI and A2 operate as a compressor or as a pump and are driven by the expansion motor. When using the described piston pump as a compressor, the inner working chamber A3 and an outer (left) working chamber AI could first compaction ¬ terstufe and the other outer working chamber A2 are operated as two ¬ th compressor stage.
Fig. 5 zeigt noch eine Ausführungsvariante der zuvor in den Figuren 1 bis 4 am Beispiel einer Kolbenpumpe be¬ schriebenen Kolbenmaschine. Danach ist das Gehäuse 3 je¬ weils im Bereich der hier abdichtend gelagerten Drehzylinder 6 durch ein Zusatzgehäuseteil 3d, 3e mit im We¬ sentlichen kreiszylindersegmentförmigem Arbeitsraum er- weitert. In dem Zusatzgehäuseteil 3d, 3e, in dessen Sei¬ tenwänden 22, 23 jeweils ein Einlassventil 24a, 24b und ein Auslassventil 25a, 25b vorgesehen sind, ist jeweils eine mit dem jeweiligen Drehzylinder 6 verbundene weitere Doppelkolbenplatte 20, 21 angeordnet, die gleichzeitig mit der ersten und zweiten Doppelkolbenplatte 1, 2 ange¬ trieben werden. Dadurch entstehen vier Zusatzarbeitskammern A5, A6 und A7, A8, die ebenfalls als Pumpe oder Ver¬ dichter oder Expansionsmotor arbeiten können. In jedem Fall ist in der Ausführungsform nach Fig. 5 eine Vielzahl vorteilhafter Anwendungsmöglichkeiten denkbar. Die weiteren Doppelkolbenplatten 20, 21 haben in der Ausführungsform gemäß Fig. 5 die gleiche Länge wie die ersten und zweiten Doppelkolbenplatten 1, 2. Jedoch kann die Länge dieser zusätzlichen Doppelkolbenplatten 20, 21 auch von der Länge der ersten und zweiten Doppelkolbenplatten 1, 2 abweichen. Das heißt, die zusätzlichen Doppelkolbenplat- ten können kürzer oder länger als die ersten und zweiten Doppelkolbenplatten sein oder eine mit diesen übereinstimmende Länge aufweisen. Mit kürzeren Doppelkolbenplat¬ ten 20, 21 und entsprechend kleineren Volumina der Zu- satzarbeitskammern könnte die anhand der Fig. 5 beschrie¬ bene Kolbenmaschine beispielsweise sehr gut als Mehrstu¬ fenkompressor oder mehrstufige Vakuumpumpe betrieben werden . Wie Fig. 6 zeigt, ist die anhand der Figuren 1 bis 4 mit zwei kreiszylindersegmentförmigen Gehäuseteilen 3a, 3b und zwei in diesen angeordneten Doppelkolbenplatten 1, 2 beschriebene Kolbenmaschine durch weitere nebeneinander, jedoch um 180° gedreht zueinander angeordnete Gehäusetei- le mit Doppelkolbenplatten beliebig erweiterbar. Die Kolbenpumpe gemäß Fig. 6 weist drei Gehäuseteile 3a, 3b und 3c mit in diesen parallel zueinander synchron verschwenkbaren, aber jeweils in entgegen gesetzter Richtung direkt angetriebenen Doppelkolbenplatten 1, 2, 27 auf, wobei zwei äußere (kleine) Arbeitskammern AI, A2 und zwei innere (große) Arbeitskammern A3, A4 gleicher Größe gebildet werden. Der Antrieb erfolgt in der gleichen Weise wie oben anhand der Figuren 1 bis 4 beschrieben. Selbstverständlich kann auch diese erweiterte Ausführungsvariante, wie anhand der Fig. 5 dargestellt, mit Zusatzgehäusetei¬ len und entsprechenden zweiflügligen Doppelkolbenplatten ausgebildet sein. Die so ausgeführte Kolbenmaschine kann wiederum als mehrstufiger Kompressor, Pumpe oder Motor oder als eine Kombination aus diesen angewendet werden. Bezugszeichenliste FIG. 5 also shows a variant of the piston machine previously described in FIGS. 1 to 4 using the example of a piston pump. Thereafter, the housing 3 is depending ¬ weils in the here sealingly mounted rotary cylinder 6 weitert by an additional housing part 3d, 3e with ER in kreiszylindersegmentförmigem We ¬ sentlichen working space. In the additional housing part 3d, 3e, in whose Be ¬ tenwänden 22, 23 each have an inlet valve 24a, 24b and an outlet valve 25a, 25b are provided, in each case one connected to the respective rotary cylinder 6 further double piston plate 20, 21 is arranged, which simultaneously with the first and second double piston plate 1, 2 are ¬ driven. This results in four additional working chambers A5, A6 and A7, A8, which can also work as a pump or Ver ¬ denser or expansion engine. In any case, in the embodiment of Fig. 5, a variety of advantageous applications conceivable. The further double piston plates 20, 21 in the embodiment according to FIG. 5 have the same length as the first and second double piston plates 1, 2. However, the length of these additional double piston plates 20, 21 can also deviate from the length of the first and second double piston plates 1, 2 , That is, the additional double piston plate th can be shorter or longer than the first and second double-piston plates or have a matching length with them. Could set working chambers with shorter Doppelkolbenplat ¬ th 20, 21 and correspondingly smaller volumes of the inlet 5 beschrie ¬ bene piston machine with reference to FIGS., For example, very well be operated as Multistage ¬ fenkompressor or multi-stage vacuum pump. As shown in FIG. 6, the piston machine described with reference to the figures 1 to 4 with two circular cylinder segment-shaped housing parts 3a, 3b and two arranged in these double piston plates 1, 2 by further side by side, but rotated by 180 ° to each other arranged housing parts with double piston plates can be extended as desired , The piston pump according to FIG. 6 has three housing parts 3 a, 3 b and 3 c with double piston plates 1, 2, 27 that are synchronously pivotable in parallel with each other but each directly driven in the opposite direction, two outer (small) working chambers AI, A2 and two inner (large) working chambers A3, A4 of the same size are formed. The drive takes place in the same manner as described above with reference to Figures 1 to 4. Of course, this extended embodiment, as shown with reference to FIG. 5, with Zusatzgehäusetei ¬ len and corresponding double-lobed double-piston plates may be formed. The piston engine thus constructed can be used in turn as a multi-stage compressor, pump or motor or as a combination of these. LIST OF REFERENCE NUMBERS
