Claims (10)

  1. Flüssigkeitsringkompressor, gekennzeichnet durch einen Exzenterinnenrotor (6), der auf Achsen (8, 9) eines Ko-Rotors (3) für den Flüssigkeitsring aufgenommen ist, wobei das Lager des Ko-Rotors (11) außerhalb derselben Achsen liegt und auf jeder Seite in einer Umhüllung eingeschlossen ist, wobei auf jeder Seite des Lagers (11) eine rotierende Dichtlippe (82) angeordnet ist, wobei die Lippe (83) von dieser Dichtlippe (82) bei niedriger Geschwindigkeit an den Achsen (8, 9) anliegt, und wobei die Lippe (83) bei hoher Geschwindigkeit nach außen hervorstehend wird und sich infolge von Zentrifugalkräften selbst von den Achsen abhebt, wobei Durchgangslöcher (81) durch die Seitenwände des Ko-Rotors angeordnet sind und Lager vorgesehen sind, deren Volumen innerhalb des Flüssigkeitsrings gegenüber der einschließenden Hülle (1) belüftet ist, so dass kein Differenzdruck zwischen den Lagern und den Dichtungen der Lager erzeugt wird.
  2. Kompressor nach Anspruch 1, dadurch gekennzeichnet, dass der Rotor (6) an seiner Peripherie eine Anzahl von Zellen (61) mit halbzlindrischer Form aufweist, wobei der Bogen der Mitte zugewandt ist.
  3. Kompressor nach Anspruch 1 bis 2, dadurch gekennzeichnet, dass die Zellen (61) des Rotors (6) radiale Kanalöffnungen (62) aufweisen, die auf jeder Seite von einem kreisförmigen, glatten Abschnitt (63) umgeben sind, zwecks Abdichtung gegenüber einem stationären Kommutator (7), der in der Mitte des Rotors platziert ist.
  4. Kompressor nach Anspruch 1 bis 3, dadurch gekennzeichnet, dass von dem Loch (75) in dem Kommutator (7) in dem Kompressionssektor Flüssigkeit injiziert wird, wo die Flüssigkeitsstrahlen von den Rändern der Kanalöffnung (62) zu den Zellen (61) des Rotors ausquetschen.
  5. Kompressor nach Anspruch 1 bis 4, dadurch gekennzeichnet, dass der Kommutator (7) auf jeder Seite Umfangsnuten (71) aufweist, wobei Injektionsflüssigkeit unter Druck existiert und Gasleckagen entgegengewirkt wird.
  6. Kompressor nach Anspruch 1 bis 5, dadurch gekennzeichnet, dass die Peripherie des Kommutators (7) außerhalb der Lagerdichtungen des Ko-Rotors sind, so dass eine Leckage von Wasser aus dem Spalt zwischen dem Kommutator und dem Rotor aus dem Flüssigkeitsring ausgeleitet wird, ohne die Lagerdichtungen zu passieren.
  7. Kompressor nach Anspruch 1 bis 6, dadurch gekennzeichnet, dass Lager (11) für den Ko-Rotor von der Art von Kugellagern oder Rollenlagern sind.
  8. Kompressor nach Anspruch 1 bis 6, dadurch gekennzeichnet, dass die Lager (11) Seitenlager sind, wozu hydrodynamische Arten gehören.
  9. Verwendung eines Kompressors gemäß einem der Ansprüche 1 bis 8 als einen Kompressor für Luft und Gasen die mit Wasser kompatibel sind, bei denen Wasser als Injektionsflüssigkeit verwendet wird.
  10. Verwendung eines Kompressors gemäß Anspruch 1 bis 9 als einen Kompressor in einer Gasturbinenanordnung.
