Abstract

A damper for dampening shock and vibration between two structural members includes a housing secured to one of the structural members and a flexible membrane body secured to the other. The flexible membrane body defines at least parts of three hydraulic chambers which are hydraulically interconnected through hydraulic passages, whereby dampening between the two structural members is effected flexibly by the membrane body and hydraulically by the fluid in the hydraulically interconnected chambers.
