Inner lateral surface of case 3 accommodate inclined equally space apart vanes 7. Said vanes are formed by two spiral surfaces that make in meridional section a triangle profile 10 elongated at an angle to distributor axis. ^ EFFECT: minimised hydraulic losses, higher head due to stabilised working fluid flow between stages. ^ 5 cl, 5 dwg |
