    einen unteren zylindrischen Körper in Längsrichtung auf dem unteren Rand des Rings angeordnet; und
    ein Anordnung von gleichwinklig im gleichem Abstand angelegten Schaufelblaettern (10), die integral mit dem Körper des oberen und unteren zylindrischen Körpers (1) gestaltet ist;
    wobei die genannten oberen und unteren zylindrischen Körper sich getrennt rechtsdrehend und linksdrehend einzeln um ihre Achse drehen können, während die Zentriervorrichtung positioniert bleibt bedingt durch eine Verrieglungsschraube.
  2. Eine Doppeldreh Zentriervorrichtung nach Anspruch 1, wobei der besagte Ring einen Gewindestift (5) und ein Ringgewinde (8) beinhaltet.
  3. Eine Doppeldreh Zentriervorrichtung nach Anspruch 1 und 2, wobei der besagte Ring einen einheitlichen Durchmesser hat, der mit einer Ringnut (9) auf beiden Seiten versehen ist, um sich an die zylindrischen Körper anzupassen.
  4. Eine Doppeldreh Zentriervorrichtung nach Anspruch 1, wobei die Anordnung von gleichwinklig im gleichem Abstand angelegten Schaufelblaettern (10), eine obere Fläche (3) und eine untere Flaeche (2) beinhaltet, die auf der Oberflaeche des oberen zylindrischen Körpers und unteren zylindrischen Körpers ausgeformt sind.
  5. Eine Doppeldreh Zentriervorrichtung nach Anspruch 1 und 4, wobei die genannten Schaufelblaetter sich zwischen den, in Längsrichtung gegenüberliegenden Enden, des oberen zylindrischen Körpers und unteren zylindrischen Körpers erstrecken.
  6. Eine Doppeldreh Zentriervorrichtung nach Anspruch 4 und 5, bei der die genannten Schaufelblaetter sich in ringsum um den Umfang der Zentriervorrichtung befinden.
  7. Eine Doppeldreh Zentriervorrichtung nach Anspruch 4 bis 6, wobei die genannten Schaufelblaetter nach links, rechts oder gerade ausgerichtet sind.
  8. Eine Doppeldreh Zentriervorrichtung nach Anspruch 4 bis 7, wobei die Schaufelblaetter daduch gekennzeichnet sind, dass die nach links oder rechts ausgerichteten Blaetter in einem Winkel, im Bereich von 15 Grad bis 35 Grad, ausgeformt sind.
