Abstract

Rotating machine with vertical transmission shaft, suspended at its upper end and provided at its lower end with a wheel surrounded by a crankcase that includes a suction lantern that has fixed radial blades, integral with the crankcase, characterized in that said shaft pivots on a hydrostatic bearing placed under said wheel, a removable sleeve being coaxially mounted to said shaft between said suction lantern and said wheel.
