<p>In a capsular hydroelectric unit an internal belt (4) of the turbine stator is provided, on its internal side, with radial ribs (19) whereas a ring (20) oriented coaxially to the internal belt (4) of the turbine stator is mounted on those butt-end surfaces of the ribs (19) which are facing the upper water. The ring (20) carries a thrust bearing (17) which supports in the axial direction the shaft (7) of the hydroelectric unit. </p> |
