Abstract

Inventia se refera la un rotor pentru un compresor centrifugal, destinat ridicarii presiunii aerului sau a altor gaze. Rotorul prezentat în patru variante constructive rezolva problema de micsorare a marimii componentei tangentiale a vitezei de iesire a gazelor din rotor, pentru aceea ca paletele au partea lor periferica prevazuta cu cîte o curbura a carei concavitate opusa sensului de rotatie a rotorului.
