Abstract[English]
A sealing arrangement for a rotary device includes a seal member configured to selectively seal against fluid passing between two chambers. The seal member seals against fluid when in an actuated state and does not provide such sealing when in a deactuated state. A transition member maintains the seal member in the deactuated state during an initial configuration of the rotary device. After a time, the rotary device is transitioned (e.g., using a tool) to a subsequent configuration in which the seal member is actuated. Actuating the seal members during a mid-life of the rotary device enhances the life expectancy of the rotary device.[French]
L'invention concerne un agencement d'étanchéité pour un dispositif rotatif qui comprend un élément de joint d'étanchéité configuré pour assurer l'étanchéité sélective vis-à-vis d'un fluide passant entre deux chambres. L'élément de joint d'étanchéité assure l'étanchéité vis-à-vis d'un fluide lorsqu'il est dans un état activé et ne fournit pas une telle étanchéité lorsqu'il est dans un état désactivé. Un élément de transition maintient l'élément de joint d'étanchéité dans l'état désactivé pendant une configuration initiale du dispositif rotatif. Après un temps, le dispositif rotatif subit une transition (par exemple, à l'aide d'un outil) vers une configuration ultérieure dans laquelle l'élément de joint d'étanchéité est activé. L'actionnement des éléments de joint d'étanchéité à mi-vie du dispositif rotatif permet d'augmenter la durée de vie du dispositif rotatif.
