Abstract

Scrollmaschine (2), insbesondere Spiralverdichter, für ein Medium, insbesondere ein Kältemittel, aufweisend ein Maschinengehäuse (10) mit einer Längsachse (X) und einem Einlass und einem Auslass für das Medium, wobei in dem Maschinengehäuse (10) entlang der Längsachse (X), eine Antriebseinheit (400) mit einer Antriebswelle (420), die durch eine erste Lagereinheit (450) und eine zweite Lagereinheit (300) an dem Maschinengehäuse (10) gelagert ist, eine erste Spiraleinheit (100) mit einem Spiralkanal (120) mit einem inneren (125) und einem äußeren Endbereich (126),
eine zweite Spiraleinheit (200) mit einem Spiralkanal (220) vorgesehen ist, und wobei die erste (100) und die zweite Spiraleinheit (200) ineinandergreifen, wobei die erste Spiraleinheit (100) entlang einer Orbitalbahn relativ zu der zweiten Spiraleinheit (200) bewegt werden kann, wobei der Einlass (11) mit den äußeren Endbereichen (126, 226) in Fluidkommunikation steht und der Auslass (12) mit den inneren Endbereichen (125, 225) in Fluidkommunikation steht, und wobei das Medium in dem Maschinengehäuse (10) entlang mehrerer Strömungspfade von dem Einlass (11) zu den äußeren Endbereichen (126, 226) strömen kann, und dass die Antriebswelle (420) einen Hohlwellenabschnitt (424) aufweist, durch den einer der Strömungspfade geführt ist.
Kälteanlage mit einer solchen Scrollmaschine.
