Abstract
A propellant storage construction having a chamber for storing the propellant and a passage leading to the chamber and containing a valve unit therein for opening and closing the passage, the passage having a flow restricting unit therein intermediate the valve unit and the chamber to limit the flow rate of the propellant from the chamber through the valve unit to a certain low flow rate when the valve unit is in an open position to dispense the propellant. The flow restricting unit has a part thereof providing a full flow rate therethrough at a substantially greater flow rate than the certain low flow rate when the valve unit is in an open position to permit a charge of the propellant to be fed through the open valve unit to the chamber for filling the chamber with the propellant.
