ABSTRACT:
A fluid supply for an occupant restraint system includes a pair of concentric cylindrical vessels defining inner and outer fluid chambers in fluid communication with each other and with a discharge passage which is normally closed by a shearable member and with expandable confinement. A valve member is slidingly carried within the inner cylinder, exposing one end of the valve member to the inner fluid chamber, and partially defines a control pressure chamber providing metered communication therefrom to the inner fluid chamber. The valve is responsive to the difference in pressure between the control chamber and the inner chamber to move from a position restricting flow from the outer fluid chamber to the inner to a position allowing relatively free flow.
A shearing member is also provided for opening the discharge passage in response to the occurrence of a collision.
