Abstract
A propellant storage construction having a storing chamber for storing the propellant and a passage leading to the storing chamber and containing a valve unit therein for opening and closing the passage. The construction has a pressure regulator operatively associated with the valve unit for operating the valve unit in relation to the pressure of the propellant, the pressure regulator comprising a self-contained capsule having a movable wall for engaging the valve unit and an opposed wall spaced therefrom by a side wall. The construction has a wall cooperating with the capsule to define an output chamber for receiving propellant dispensed from the storing chamber through the valve unit. An annular sealing member is disposed between and against the capsule and the wall to define the output chamber therebetween. The annular sealing member is telescoped onto the side wall of the capsule and thereby engages and seals against the side wall of the capsule intermediate the opposed wall and the movable wall of the capsule.
