shock absorbers. SUBSTANCE: device has supporting bases joined to concentric external and internal telescopic springs with rectangular-section turns, flexible shells, and insulated cavities of damping media engageable with springs; one of mentioned cavities is located in space between external and internal springs and other one, inside internal spring; both bases are provided with throttling holes and ducts; base connected to largest turns of both springs has calibrated holes closed with breakable membrane; space between springs and bases as well as clearance between external flexible shell and external spring are filled with viscous plastic material; internal spring interior is filled with foam plastic. EFFECT: improved energy dissipation under dynamic loads. 1 dwg
