ABSTRACT:
A device for inflating the floating body of lifesaving equipment, in which gas under pressure is released from a compressed gas containing container, normally closed by a diaphragm, into lifesaving equipment to be inflated, by causing a striker to pierce the diaphragm. The striker is movable against the diaphragm, selectively by a manually operable lever or by the thrust of a spring. In the last mentioned instance, a spring is held in its loaded condition by a control element having a section adapted to disintegrate in water. A lever system including a pivoting lever operatively engages the striker. When the pivoting lever is in its ineffective position and the spring is in loaded condition, the pivoting lever is continuously urged to its effective position, in which the lever system causes the striker to pierce the diaphragm. As long as the water soluble section of the control element is intact, the control element prevents movement of the pivoting lever from being moved by the spring to its effective position, but this action of the pivoting lever ceases as soon as the water soluble section disintegrates or dissolves under the influence of water.
