ABSTRACT:
An impact-absorbing shock module comprises two pylons telescopingly engaged to permit axial and rotational motion therebetween. A resilient element, such as a spring-fluid combination, a plurality of interconnected disks, or a Belleville spring, provides axial shock absorption. A tubular torque-resisting cuff provides rotational resistance, or torsion-resistance. A fluid valve is optionally provided so that the fluid pressure may be varied to adjust the torsion resistance.
