Claims (4)

  1. Toruspumpe mit einem Gehäuse (20), einem diskusartigen Rotor (46), der im Gehäuse (20) zwecks Umlaufs um eine Achse (A) montiert ist und an seinem Außenumfang Flügel (58, 60) aufweist, die beim Umlauf des Rotors (46) ein Medium entlang einer toroidalen Pumpenkammer im Gehäuse (20) fördern, die sich in Umfangsrichtung um die Achse (A) im Wirkungszusammenhang zum Umlaufweg der Flügel (58, 60) des Rotors (46) erstreckt, wobei der Rotor (46) und das Gehäuse (20) einander gegenüberliegende ebene Seitenflächen aufweisen, die normal zur Achse (A) verlaufen und radial innerhalb der Flügel (58, 60) und der Pumpenkammer (28, 38) angeordnet sind, mit einem Spalt von genügender Weite um einen freien Umlauf des Rotors (46) in Bezug auf das Gehäuse (20) zu erlauben, wobei der Rotor (46) eine Mehrzahl von Taschen (80, 82, 84) in den Seitenflächen aufweist, um eine Leckage von Medium durch den Spalt während des Umlaufs des Rotors (46) zu unterbinden,
    gekennzeichnet durch die folgenden Merkmale:
    1.1 die Taschen sind Sackbohrungen (80, 82, 84);
    1.2 die Sackbohrungen (80, 82, 84) sind auf den beiden ebenen Seitenflächen des Rotors (46) vorgesehen.
  2. Toruspumpe nach Anspruch 1, dadurch gekennzeichnet, daß wenigstens eine Serie von Sackbohrungen (80) auf demselben Radius um die Achse (A) angeordnet ist.
  3. Toruspumpe nach Anspruch 2, dadurch gekennzeichnet, daß wenigstens eine weitere Serie von Sackbohrungen (82, 84) vorgesehen ist, und daß jede Sackbohrung einer Serie auf demselben Radius angeordnet ist, daß jedoch die Serien von Sackbohrungen auf unterschiedlichen Radien um die Achse (A) angeordnet sind.
  4. Toruspumpe nach Anspruch 2, dadurch gekennzeichnet, daß die Sackbohrungen einer Serie in Bezug auf die Sackbohrungen einer anderen Serie von Sackbohrungen versetzt angeordnet sind.
