Abstract

A gas-generating valve for releasing a pressurized fluid from a container and releasing a gas into the fluid from a gas generator after the fluid has been released. This is accomplished by opening an outlet port on the container, preferably by the action of a piston moving relative to a casing. Gas from the gas generator is then released into the fluid, again preferably by the movement of the piston.

Claims

1. A gas generator, valve and fluid container arrangement comprising:

a. a container capable of holding a gas under pressure;

b. said container having an outlet port;

c. a valve casing being movable relative to said outlet port;

d. a stationary piston in sealed, slidable relation to said casing;

e. a removable port seal closing said outlet port and removable in cooperation with the movement of said casing;

f. means for moving said casing;

g. means for releasing gas from said gas generator into said fluid container after moving said casing to remove said seal from said outlet port.

2. A gas generator, valve and fluid container arrangement comprising:

a. a container capable of holding a gas under pressure;

b. said container having an oulet port;

c. a valve casing;

d. a piston in sealed, slidable relation within said casing, said piston being a movable part relative to said outlet port;

e. a removable port seal closing said outlet port and removable in cooperation with the movement of said piston;

f. means for moving said piston; and

g. means for releasing gas from said gas generator into said fluid container after moving said piston to remove said seal from said outlet port wherein said gas generator is inside said container adjacent said outlet port and said gas from said gas generator is released inside said container.

3. A gas generator, valve and fluid container arrangement comprising:

a. a container capable of holding a gas under pressure;

b. said container having an outlet port;

c. a valve casing;

d. a piston in sealed, slidable relation within said casing, said piston being a movable part relative to said outlet port;

e. a removable port seal closing said outlet port and removable in cooperAtion with the movement of said piston;

f. means for moving said piston; and

g. means for releasing gas from said gas generator into said fluid container after moving said piston to remove said seal from said outlet port wherein said means for moving said movable part is gas from said gas generator.

4. A gas generator, valve and fluid container arrangement comprising:

a. a container capable of holding a gas under pressure;

b. said container having an outlet port;

c. a valve casing;

d. a piston in sealed, slidable relation within said casing, said piston being a movable part relative to said outlet port;

e. a removable port seal closing said outlet port and removable in cooperation with the movement of said piston;

f. means for moving said piston; and

g. means for releasing gas from said gas generator into said fluid container after moving said piston to remove said seal from said outlet port wherein said port seal is a portion of said piston.

5. A gas generator, valve and fluid container arrangement comprising:

a. a container capable of holding a gas under pressure;

b. said container having an outlet port;

c. a valve casing;

d. a piston in sealed, slidable relation within said casing, said piston being a movable part relative to said outlet port;

e. a removable port seal closing said outlet port and removable in cooperation with the movement of said piston;

f. means for moving said piston; and

g. means for releasing gas from said gas generator into said fluid container after moving said piston to remove said seal from said outlet port wherein said gas generator is in communication with a percussion primer and wherein said movable part of said port seal has a firing pin which aligns with said percussion primer.
