Claims (8)

1. Vätskeringpump innefattande en rotor (20, 500, 602, 604, 606) som bestir av flera, huvudsakligen radiellt utskju-tande vingar (24, 502, 504, 506), placerade med vinkeldel-ning kring en rotoraxel (22), ett hus (50, 200, 300, 302, 304), en inloppsanordning (64, 66, 68, 210) samt en utloppsanord-ning (70, 72, 74, 222), belägna i axial riktning mellan rotor-vingarnas ändar, pi ställen utmed periferin, som är förskjut-na i förhillande till varandra, i ett ringformigt spir, som uppstir i mellanrummen mellan vingarna i axial riktning, kännetecknad därav, att inloppsanordningen resp. utloppsanordningen är fästade vid huset sisom konstruktivt separata enheter.
2. Vätskeringpump enligt patentkravet 1, kännetecknad därav, att den är försedd med itminstone tvi inloppsanordningar (64, 66, 68) samt motsvarande antal ut-loppsanordningar (70, 72, 74), varvid en inloppsanordning och en utloppsanordning är placerade utmed periferin pi av-stind fran varandra pi ett ställe mellan rotorns ändar, och den andra inlopps- resp. utloppsanordningen är förskjutna i förhillande till varandra utmed periferin pi ett ställe mellan rotorns ändar samt i axial riktning pa avstind frin det första stället.
3. Vätskeringpump enligt patentkravet 1, kännetecknad därav, att utloppsanordningen uppvisar ytor som begränsar ett snävt driftspelrum mellan dessa ytor och de vingkanter som definierar det ringformiga spiret, och att inloppsanordningen har ytor som begränsar ett relativt vitt spelrum mellan dessa ytor och de vingkanter som definierar det ringformiga spiret.
4. Vätskeringpump enligt patentkravet 1, kännetecknad därav, att inlopps- resp. utloppsanordnin-garna är justerbara radiellt i förhillande tili rotorn.
5. Vätskeringpump enligt patentkravet 4, kännetecknad därav, att de vingkanter som definierar det ringformiga spiret konvergerar i riktning mot axeln, och
