<p>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).</p> |
