Abstract

Det fremlegges et apparat med progressivt hulrom. I noen utførelsesformer inneholder apparatet en stator med en indre overflate som har en rekke lober og en rotor anordnet i statoren som har et ulikt antall lober. Statorlobene definerer en stor diameter og en mindre diameter, hvor den store diameteren omskriver statorlobene og den mindre diameter innskriver statorlobene. En rotor og en stator, definert som stor diameter delt på mindre diameter, er valgt fra gruppen bestående av 1,350 eller mindre for et apparat med progressive hulrom med en stator med to lober, 1,263 eller mindre for tre lober, 1,300 eller mindre for fire lober, 1,250 eller mindre for fem lober, 1,180 eller mindre i seks lober, 1,175 eller mindre for sju lober, 1,150 eller for åtte lober, 1,125 eller mindre for ni lober, og 1,120 eller mindre for 10 lober.
