Abstract
A sealing structure for a gas turbine blade which pivots about a pivot shaft. A split ring is located in a groove on the shaft, in which the ring can be embedded and held by a bush. When the blade is fitted, the bush abuts against a wall of the stator, slides on the pivot shaft and frees the ring, which expands and forms the seal. The invention relates to gas turbines where the stator blades have a variable setting.
