An inflation system , comprising: a housing assembly defining an inlet cavity with an inlet and an outlet comprising a flow restricting orifice and a command cavity ; a poppet disposable within the housing assembly to assume open or closed positions; multiple seals between the housing assembly and the poppet; a pressurized bottle to pressurize the inlet cavity through the inlet to bias the poppet toward the closed position; and characterized by a solenoid valve interposable between the pressurized bottle and the command cavity , wherein the housing assembly comprises first and second housings and a baffle interposed between the first and second housings ; wherein the first housing defines: the inlet through which the pressurized bottle pressurizes the inlet cavity , and the outlet through which pressurized fluid exits the inlet cavity with the poppet assuming the open position; wherein the flow restricting orifice comprises an inward taper; the solenoid valve being normally closed and selectively openable to permit fluid flow from the pressurized bottle to pressurize the command cavity such that the poppet is biased toward the open position whereby pressurized fluid flows through the outlet, wherein the solenoid is configured to be de-energized during command cavity pressurization whereupon pressures applied on the poppet by the seals and the flow restricting orifice maintain the poppet in the open position. a housing assembly defining an inlet cavity with an inlet and an outlet comprising a flow restricting orifice and a command cavity ; a poppet disposable within the housing assembly to assume open or closed positions; multiple seals between the housing assembly and the poppet; a pressurized bottle to pressurize the inlet cavity through the inlet to bias the poppet toward the closed position; and characterized by a solenoid valve interposable between the pressurized bottle and the command cavity , wherein the housing assembly comprises first and second housings and a baffle interposed between the first and second housings ; wherein the first housing defines: the inlet through which the pressurized bottle pressurizes the inlet cavity , and the outlet through which pressurized fluid exits the inlet cavity with the poppet assuming the open position; wherein the flow restricting orifice comprises an inward taper; the solenoid valve being normally closed and selectively openable to permit fluid flow from the pressurized bottle to pressurize the command cavity such that the poppet is biased toward the open position whereby pressurized fluid flows through the outlet, wherein the solenoid is configured to be de-energized during command cavity pressurization whereupon pressures applied on the poppet by the seals and the flow restricting orifice maintain the poppet in the open position. the inlet through which the pressurized bottle pressurizes the inlet cavity , and the outlet through which pressurized fluid exits the inlet cavity with the poppet assuming the open position; wherein the flow restricting orifice comprises an inward taper; the solenoid valve being normally closed and selectively openable to permit fluid flow from the pressurized bottle to pressurize the command cavity such that the poppet is biased toward the open position whereby pressurized fluid flows through the outlet, wherein the solenoid is configured to be de-energized during command cavity pressurization whereupon pressures applied on the poppet by the seals and the flow restricting orifice maintain the poppet in the open position. <EOS>
