ABSTRACT:
A valve for controlling the flow of fluid through a flow path, which valve comprises a housing defining a flow path and having two indented portions about the flow path, a poppet mounted within each indented portion such that the internal end of each indented portion defines a seat which provides a fluid tight seal when the associated poppet head is held against the seat, a spring associated with each poppet for holding each poppet against each seat, a rigid moveable member associated with each poppet and adapted to alter the orientation of the associated poppet relative to its seat and thereby seal or unseal the flow path around the poppet, and an actuator for moving each movable member; and inflator apparatus incorporating at least one valve.
