Claims (5)

1. Rotor-statorkombination för användning i en flotations-separeringscell, till vilken kombination hör en stator (18), som innehaller en grupp ringformigt placerade lodräta, fasta statorplattor (64), vilkas underkantdelar ligger ätskils frän cellens botten och framkantsdelar definierar ett centralt beläget hälrum, en rotorstomme (16), som placerats i nämnda hälrum och försetts med en grupp rotorplattor (44), vilka envar har en kurvlinje-, parabolisk eller spiralsegmentformad omkrets (63), statorplattornas (64) nämnda framkantsdelar mots-varar till formen rotorplattorna (44) och de ligger radiellt ätskils frän rotorplattornas omkrets, väsentligen pä ett konstant avständ, utmed stator- och rotorplattornas gemensamma längd, kännetecknad därav, att de nedät i nämnda centralt belägna hälrum näende rotorplattorna (44) sträcker sig en väsentlig sträcka förbi statorplattornas (64) underkant.
2. Kombination enligt patentkravet 1, kännetecknad därav, att nämnda väsentliga sträcka, varmed rotorplattorna (44) när förbi statorplattorna (64), är ca 1/3 av rotorplattornas längd.
3. Kombination enligt patentkravet 1, kännetecknad därav, att tili rotorn (16) hör en pol (42), rotorplattorna (44) utskjuter radiellt frän polen (42) och de har delar, som sträcker sig uppät och bortät frän polen och vilka delar täckes av en täckskiva och täckskivan (46) har en öppning (54), som öppnar sig tili den utmed rotorns (16) längdaxel befintliga och rotorplattornas (44) och polens (42) Övre ända bildande gaskammaren (56).
4. Kombination enligt patentkravet 3, kännetecknad därav, att rotorplattorna (44) har en kurvlinjeformad omkrets
