Title
(EN) Improvements in or relating to a gas supply
Abstract
(EN)
A gas supply comprises a bottle 1 of compressed gas with at least one opening 4, 5 formed in the wall of a bottle sealed with a metallic foil 6, 7 across the opening, an element 10 being provided on the exterior of the bottle in engagement with the foil which in response to a signal moves in such a way as to cause a part 20 of the element to tear or cut the foil, permitting gas to escape to inflate, for example, an air-bag. The element 10 may be in the form of a piston movable within a bore 3 by firing a pyrotechinc charge 15. The foil may be ruptured by a pointed flange 19, or a knife blade (24, Figure 3). Alternatively the foil may be glued or soldered (Figure 4) to the piston so that it is torn by the movement of the piston, or a tab attached to both the piston and foil (Figures 5 and 6) which is pulled when the piston moves.
