Abstract

Turbokone, joka käsittää ensimmäisen vaiheen (101), joka käsittää ensimmäisen radiaalisen juoksupyörän (103), toisen vaiheen (102), joka käsittää toisen radiaalisen juoksupyörän (104), liitoskanavan (109), joka on konfiguroitu muodostamaan fluidinsiirtoyhteys ensimmäisen ja toisen vaiheen välille, akselin (110), joka on kiinnitetty ensimmäiseen ja toiseen radiaaliseen juoksupyörään, ja laakerikokoonpanon (111), joka on aksiaalisesti ensimmäisen ja toisen radiaalisen juoksupyörän välissä ja joka on konfiguroitu tukemaan akselia. Ensimmäisen radiaalisen juoksupyörän takapinta osoittaa laakerikokoonpanoa kohti, ja toisen radiaalisen juoksupyörän takapinta osoittaa poispäin laakerikokoonpanosta. Runko-osio (113), joka ympäröi ja tukee mekaanisesti laakerikokoonpanon, muodostaa rengasmaisen kanavan (112), jolla on aksiaalinen fluidinsiirtoyhteys toiseen radiaaliseen juoksupyörään, sisäseinän.
