Abstract

Hydraulic sealing device for gases, for a rotating shaft passing through a wall of an enclosure under gaseous pressure, more particularly intended for hydroelectric groups of the bulb type comprising a pressurized enclosure, characterized in that it includes a crown fixed ring that surrounds the shaft and in which an annular chamber, supplied with lubricating liquid under pressure, separates two annular support surfaces of a ring integral with the shaft and can move axially on this shaft, said ring being subjected to sense of its support on the fixed crown, to the action of the gaseous pressure and of springs that rest on the tree.
