Sealing structure for a pivoting blade of a turbomachine

Sealing structure for a blade (8) of a turbomachine pivoting about a spindle (9). A split ring (11) is housed in a groove (10) into which it can be driven and held by a sleeve (22). When the blade is fitted, the sleeve (22) abuts against a wall of the stator (1), slides on the pivot (9) and releases...

Beschreibung
Zusammenfassung:	Sealing structure for a blade (8) of a turbomachine pivoting about a spindle (9). A split ring (11) is housed in a groove (10) into which it can be driven and held by a sleeve (22). When the blade is fitted, the sleeve (22) abuts against a wall of the stator (1), slides on the pivot (9) and releases the ring (11) which expands and provides sealing. The invention relates to some turbomachines in which the stator blades have what is known as variable pitch.
