Abstract

En Statoranordning for en skruegirpumpe eller -motor omfatter en stator (10) av fleksibelt materi- ale med en skruelinjeformet boring, mens den sylind- riske ytre flate (14) av statoren er forsynt med en flerhet av aksialt forløpende periferisk adskilte utragende fremspring (16). Et stivt hovedsakelig rørformet legeme (22) er forsynt med samvirkende utsparinger (24) og kan utformes av et enhetlig rer eller av en flerhet av skallelementer med et samvirk- ende strammearrangement (32 - 36). Sideflatene (18, 20) av fremspringene er plane og er enten innbyrdes parallelle eller skråner mot hverandre i retning radialt utad.
