A thrust absorber (130) is interposed between a thrusting means (80) and an anchoring means (60) that cooperate to axially displace another member (30). The thrust absorber (130) includes an enclosure (64) fixed to the anchor means (60) and a retainer (62) connected to the thrusting means (80). A biasing member (136) is operably associated with the retainer (62). During an overthrust condition, the thrusting means (80) imparts a thrust force to the member (30), but the member (30) is not substantially axially displaced. In such a condition, the biasing means (136) absorbs the thrust that the thrusting means (80) would otherwise impart to the member (30). A dampener (92) is also included to dampen the movement of the thrusting means (80) and anchoring means (60) when the anchoring means (60) is no longer anchoring the thrusting means (80).
L'invention concerne un amortisseur de poussée interposé entre un dispositif de poussée et un dispositif d'ancrage qui coopèrent de manière à déplacer axialement un autre élément. L'amortisseur de poussée comporte une enceinte fixée au dispositif d'ancrage et un dispositif de retenue relié au dispositif de poussée. Un élément de sollicitation est fonctionnellement associé au dispositif de retenue. Lors d'une situation de chevauchement, le dispositif de poussée imprime une force de poussée à l'élément, mais ce dernier n'est pas sensiblement déplacé de manière axiale. Dans une telle condition, le dispositif de sollicitation absorbe la poussée que le dispositif de poussée aurait imprimer audit élément. Un amortisseur, également compris, permet d'amortir le mouvement du dispositif de poussée et du dispositif d'ancrage lorsque ce dernier ne retient plus le dispositif de poussée.
