Abstract:
The invention relates to a sealing device for the partition penetration of a connecting rod of a turboprop fan blade orientation control system. The device includes a bellows (60) of trunconical shape designed to allow passage of the connecting rod (50a) and having, at its wider end, means (62, 64) of attachment to the partition (58) to be sealed and, at its narrower end, an O-ring through which the connecting rod is free to slide.
