REBOUND CONTROL FOR ENERGY ABSORBER UNIT

摘要

A thermoplastic rebound control and fluid sealing sleeve having a high degree of resilience is disposed between telescopically mounted outer and inner cylinders of an energy absorbing unit. When deflected the sleeve provides a mechanical drag load between the cylinders as the inner cylinder telescopically moves within the outer cylinder. The added friction of the drag load effectively reduces return speed of the cylinders from a telescoped retracted position to a normal extended position to eliminate or substantially reduce damage that may otherwise occur from absorber unit rebound.
