Abstract
The sealing device comprises a central bar and two angular segments mounted end to end in a groove situated along each crest of the rotor. Each groove is formed in the rotor at the level of the bar and in a drum sliding at the level of each segment. A spring exerts a centrifugal radial force on the segments, the bar and each segment are in contact through oblique support surfaces and stop surfaces are provided between each segment and each drum to transmit to the latter the axial component, due to the said oblique surfaces, of the total radial force of the spring.
