ABSTRACT:
A liquid energy absorber device including an elongated liquid energy absorber member mounted on a base, an annular elastomeric member also mounted on the base in surrounding relationship to the liquid energy absorber member, a sleeve mounted on the liquid energy absorber member for sliding movement, a plate connected to the sleeve and supported on the end of the annular elastomeric member remote from the base, grooves in the plate and in the portion of the sleeve facing the liquid energy absorber member to conduct atmospheric air to a space which is formed between the sleeve and the elastomeric member as the latter distorts in operation to thereby cool the liquid energy absorber member and the annular elastomeric member, with the annular elastomeric member being longer than the liquid energy absorber member so that there is deflection of the annular elastomeric member prior to the activation of the liquid energy absorber member.
