ABSTRACT:
A self-inflating device for lifesaving equipment, in which the lifesaving equipment automatically inflates itself as soon as a piercing member forming part of the device is projected by a spring-urged shank into a closure diaphragm of a compressed air containing vessel. The spring-urged shank pertaining to a first housing section is prevented from hitting the piercing member by a preferably annular member arranged in a second housing member disengageably connected to the first housing member, as long as the device is not in the water but as soon as the device is in the water, the preferably annular member disintegrates and thereby permits the shank under the influence of the spring acting thereon to cause the piercing member to pierce the closure diaphragm for the compressed air containing vessel which then dispenses its content into the lifesaving equipment to be inflated. To ready the device for a new self-inflation, it is merely necessary to disengage the second housing section from the first housing section to allow a spring associated with the piercing member to lift the latter to its starting position, to replace the ring member and to connect a new pressure medium containing vessel and to again connect the first housing section to the second housing section.
