SHOCK ABSORBING APPARATUS Russian patent published in 1997 - IPC

FIELD: mechanical engineering; devices absorbing and dissipating energy of shocks. SUBSTANCE: shock absorbing apparatus has cylinder 1 with piston 2 installed to provide overflowing of working liquid. Apparatus has additional spherical chamber 5 separated from main chamber by nut with seal. all seals are made in form of rings with conical surface at one side and flat base at other side. Two washers adjoin flat base. Washers are in contact with base of other ring which rests on conical surface of mated part. EFFECT: reduced thickness of cylinder walls, improved operating conditions of seal owing to rational redistribution of pressure in working chamber. 2 dwg
