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.
Claims13
An element of a valve for controlling flow of a fluid through a flow path, which element comprises a housing defining said flow path and having an indented portion about said flow path, a poppet mounted within said indented portion such that an internal end of the indented portion defines a seat which provides a fluid-tight seal when the poppet mounted within the indented portion is held against said seat, spring means for holding said poppet against said seat, rigid movable means associated with the poppet. For altering the orientation of said poppet relative to said seat and thereby seal or unseal the flow path, and actuating means for moving said movable means.
