FIELD: salvage operations.
SUBSTANCE: folded shell and a cylinder with light gas are placed into a rucksack and connected with a hose via a valve with tubular slings that lead towards the shell. Between the cylinder and the shell there is a device for automatic supply of light gas into the shell in case of a mountain climber fall. The device comprises a body, in which there is a finger-like lug of elastic material to cover the outlet from the cylinder. On the inner surface of the body along circumference with a gap from the surface of the finger-like lug there are radially directed sharp thorns.
EFFECT: increased safety by means of automatic valve opening in case of a person's fall from height.
