Abstract

Oppfinnelsen vedrører en kompressorenhet (1), særlig for undervannsdrift, innbefattende en kompressor (3) med en kompressorrotor (9), som har ett eller flere kompressortrinn (11), og videre innbefattende en elektrisk motor (2) med en stator (16) og en motorrotor (15), og et gasstett hus (4) som er forsynt med et innløp (6) og et utløp (7). Slike kompressorenheter vil være utsatt for svingninger når det dreier seg om store utførelser. Oppfinnelsen råder bot på dette, idet motorrotoren (15) har to respektive anordnede radiallagre (21, 22) på enden, et første radiallager (21) og et andre radiallager (22), mens kompressormotoren har to respektive anordnede radiallagre (23, 24) på enden, et tredje radiallager (23) og et fjerde radiallager (24), og at det mellom de to rotorene (15, 9) er anordnet en kobling (18) som overfører dreiemomenter.
