摘要:
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.

摘要:
A plural range pressure regulator construction having a housing provided with an inlet and an outlet separated by a valve seat that is controlled by a valve member that is interconnected to a flexible wall carried by the housing. Biasing means are carried by the housing for acting on one side of the wall to tend to move the wall in one direction relative to the housing, the biasing means comprising a plurality of separate spring means each acting on the wall to provide one pressure range for the pressure regulator construction. The housing has a storage space for storing one of the spring means so that the same will not act on the wall whereby the remaining spring means acting on the wall will provide another pressure range for the pressure regulator construction.
