Claims (14)

  1. System für die Abscheidung von Öl, das in den Gehäusegasen eines Verbrennungsmotors enthalten ist, umfassend eine Trennvorrichtung (20), die bestimmt ist, in einen Zirkulationskreis der Gehäusegase eingesetzt zu sein, dadurch gekennzeichnet, dass die Trennvorrichtung (20) mindestens ein Zirkulationsorgan (21) umfasst, das eine aus einem elastischen Material gemäß einer verengten Form gebildete Leitung mit einem breiteren Eingangsquerschnitt als der Ausgangsquerschnitt ist, wobei der Ausgangsquerschnitt einen in Abhängigkeit vom Gehäusegasdurchsatz variablen Durchmesser hat.
  2. System nach Anspruch 1, umfassend ferner eine Aufschlagvorrichtung (30), umfassend mindestens eine Aufschlagwand (30), die nach dem Ausgangsquerschnitt des Zirkulationsorgans (21) positioniert ist, um den Gehäusegasstrom aus dem Zirkulationsorgan (21) abzufangen.
  3. System nach Anspruch 2, wobei die Aufschlagwand (30) eine Aufschlagfläche (31) aus einem Material hat, welches das Zurückhalten des in den Gehäusegasen enthaltenen Öls begünstigt.
  4. System nach einem der Ansprüche 2 bis 3, wobei die Aufschlagwand (30) eine Aufschlagfläche (31) hat, welche ein Filtermedium vorzugsweise fest zusammenhängender Art umfasst.
  5. System nach einem der Ansprüche 2 bis 4, wobei die Aufschlagwand (30) eine Aufschlagfläche (31) hat, die ein Sieb umfasst.
  6. System nach einem der Ansprüche 2 bis 5, wobei die Aufschlagwand (30) eine poröse Aufschlagfläche (31) oder mit vielen Facetten hat.
  7. System nach einem der Ansprüche 2 bis 6, wobei die Aufschlagwand (30) eine zweite Neigung hat, wobei die zweite Neigung senkrecht zur Neigung in Richtung der ersten Ausgangsöffnung (12) ist.
  8. System nach einem der Ansprüche 2 bis 7, wobei das Zirkulationsorgan (21) derart ausgebildet ist, dass die Position des Ausgangsquerschnitts in Bezug zur Aufschlagwand (30) in Abhängigkeit vom Gehäusegasstrom schwankt.
  9. System nach einem der Ansprüche 1 bis 8, wobei das Zirkulationsorgan (21) eine Form hat, um die Ausbildung eines gegenläufigen Stroms des Gehäusegasstroms zu vermeiden.
  10. System nach einem der Ansprüche 1 bis 9, wobei das Zirkulationsorgan (21) etwa schnabelförmig ist.
  11. System nach einem der Ansprüche 1 bis 10, wobei die Trennvorrichtung (20) eine Vielzahl von Zirkulationsorganen (21) umfasst, welche den Gehäusegasstrom im Bereich der Trennvorrichtung (20) von einer vorgelagerten Zone zu einer nachgelagerten Zone in der Richtung des Gehäusegasstroms verteilen.
  12. System nach einem der Ansprüche 1 bis 11, umfassend ferner ein Abscheidungsgehäuse (10), welches mit der Trennvorrichtung (20) eine Abscheidungskammer (15) am Ausgang des Zirkulationsorgans (21) bildet, wobei das Abscheidungsgehäuse (10) im Bereich der Abscheidungskammer (15) mindestens eine erste Ausgangsöffnung (12) für die Ableitung des Öls, das von den Gehäusegasen zurückgewonnen wurde, und mindestens eine zweite Ausgangsöffnung (13) für die Ableitung der gereinigten Gehäusegase hat.
  13. System nach Anspruch 12, herangezogen in Kombination mit einem der Ansprüche 2 bis 7, wobei die Aufschlagwand (30) in der Abscheidungskammer (15) in Richtung der ersten Ausgangsöffnung (12) geneigt ausgebildet ist.
  14. System nach einem der Ansprüche 12 oder 13, wobei das Abscheidungsgehäuse (10) ferner mindestens eine Eingangsöffnung (11) für den Einlass der Gehäusegase in das Innere des Abscheidungsgehäuses (10) umfasst, wobei die Trennvorrichtung (20) im Innern des Abscheidungsgehäuses (10) derart positioniert ist, dass die Abscheidungskammer (15) auf der Seite der ersten (12) und zweiten (13) Ausgangsöffnungen und eine Einlasskammer (14) im Bereich der Einlassöffnung (11) gebildet ist.
