Abstract

En løpehjulsammenstilling (10) er for en fluidmaskin, slik som en kompressor (2), og inkluderer et første hovedlegeme (12) og et andre legeme (14). Hovedlegemet (12) inkluderer en første seksjon (16) som tilveiebringer minst en vesentlig del av enten en løpehjulskive (D) eller et løpehjulsdeksel (C), og en andre seksjon (18) atskilt generelt aksielt fra den første seksjonen (16), og som tilveiebringer en del av den andre av skiven (D) eller dekselet (C). Et antall integrert utformede blader (20) strekker seg mellom og forbinder hovedlegemets (12) første og andre seksjoner (16, 18), slik at hovedlegemet (12) generelt har en konstruksjon i ett stykke. Et antall strømningskanaler (30) er definert mellom bladene (20), og et antall atkomståpninger (32) strekker seg inn i strømningskanalene (30). Det andre legemet (14) tilveiebringer resten av skiven (D) eller dekselet (C) og kan festes til hovedlegemet (12) for i det vesentlige å danne et løpehjul (1) og å stenge av alle atkomståpningene (32).
