Abstract
Official abstract text for this publication.
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 ( 50 a ) 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.
First claim
