Abstract

A source of regulated gas pressure is directed within a liquid sprayer tank provided by a small gas generator package adjacent the tank which, upon ignition, dissipates its energy into a hog gas plenum and thence into the tank, thereby providing sufficient pressure, upon demand, to expel liquid therefrom.

Claims

1. A gas generator device for pressurizing a liquid-containing container comprising;

a solid propellant charge capable of generating a source of high pressure gas upon ignition, a breech means to contain said solid propellant charge, a plenum chamber housing to contain said gas, said breech means being mounted within said plenum chamber housing, and a regulator means communicating with said housing and a liquidcontaining container to provide a constant pressure to the interior of said container.

2. A gas generator device for pressurizing a container comprising;

a plenum chamber housing, a cartridge breech means extending into said housing, said breech means forming an opening at a first end thereof, said breech means having attached thereto a breech block to close off said opening, said breech block being hinged on one side to said first end of said breech means, the breech block having a clasp mechanism on the other side of said block so as to latch onto a flange adjacent said first end of said breech means, thereby latching said breech block to said breech means, said breech means forming at its other end at least one aperture that communicates with the interior of said plenum chamber, a cartridge case insertable through said first end of said cartridge breech means, said cartridge case having a solid propellant charge disposed therein, the cartridge case having a first end containing a percussion cap and a second nozzle-containing end communicating with the interior of said plenum chamber through said other end of said cartridge breech means, and a firing mechanism means adjacent said percussion cAp for igniting said propellant charge when said cartridge case is enclosed within said breech means.

3. The invention as set forth in claim 2, wherein said breech block further includes a firing mechanism suspended by at least one support arm extending from said breech block, said mechanism comprising a hammer arm swivelably hinged to said support at one end and juxtaposed to a centrally located firing pin extending through said breech block at its other end, said arm being biased by a spring means against said firing pin.

4. A solid propellant cartridge case insertable in a cartridge breech mechanism comprising;

a cylindrical housing, said housing having at a first end a wall transverse to the axis of the cartridge case, the edges of said case protruding beyond the circumference of the cylinder forming a shoulder portion thereby, said shoulder having a raised lip circumferentially positioned around the outer edge of said shoulder, said lip being deformable, effecting a seal for said breech mechanism when said cartridge case is encapsulated within said breech, a primer cap means affixed to and centrally located within said end wall, a booster charge means adjacent said primer cap positioned between a solid propellant charge, said solid propellant forming a central orifice longitudinally extending through the propellant within said housing, a metal nozzle plate transverse to the axis of said cylindrical housing, forming a central orifice therein, being juxtaposed to the end of said propellant charge, and a retention means for retaining said booster charge, said propellant charge and said nozzle plate within said cylindrical housing, said retention means being an extension of said housing forming a second end thereof, said extension being crimped over the edge of said nozzle plate, thereby completing the assembly of said cartridge case.

5. The invention as set forth in claim 4, wherein said nozzle plate is formed with a centrally located protrusion surrounding said opening in said plate so as to more directly guide the exhaust gases out of said orifice when said propellant charge is ignited.

6. The invention as set forth in claim 4, further including a fine mesh screen between the end of said propellant charge and said nozzle plate so as to control the amount of residue leaving said cartridge case after said propellant charge is ignited.

7. A gas generator device for pressurizing a container comprising:

;

a plenum chamber housing, a cartridge breech means extending into said housing said breech means forming an opening at a first end thereof, said breech means having attached thereto a breech block to close off said opening, said breech means forming at its other end at least one aperture that communicates with the interior of said plenum chamber, a cartridge case insertable through said first end of said cartridge breech means, said cartridge case having a solid propellant charge disposed therein, the cartridge case having a first end containing a percussion cap and a second nozzle-containing end, said nozzle-containing end is a metal plate transverse to the axis to said cartridge case, said metal plate having an orifice formed thereby for directing exhaust gases therethrough, said plate forming an integral part of said cartridge case, said nozzle communicating with the interior of said plenum chamber through said other end of said cartridge breech means, and a firing mechanism means adjacent said percussion cap for igniting said propellant charge when said cartridge case is enclosed within said breech means.

8. A gas generator device for pressurizing a container comprising;

a plenum chamber housing, a cartridge breech means extending into said housing, said breech means forming an opening at a first end thereof, said breech means having attached thereto a breech block to close off said opening, said breech means forming at its other end at least one aperture that communicates with the inteRior of said plenum chamber, and a cartridge case insertable through said first end of said cartridge breech means, said cartridge case having a solid propellant charge disposed therein, the cartridge case having a first end containing a percussion cap and a second nozzle-containing end, said nozzle-containing end includes a metal plate transverse to the axis of said cartridge case, said metal plate having a protruding center portion forming an orifice thereby for directing exhaust gases therethrough, said plate forming an integral part of said cartridge case, said nozzle communicating with the interior of said plenum chamber through said other end of said cartridge breech means, and a firing mechanism means adjacent said percussion cap for igniting said propellant charge when said cartridge case is enclosed within said breech means.

9. A gas generator device for pressurizing a container comprising;

a plenum chamber housing, a cartridge breech means extending into said housing, said breech means forming an opening at a first end thereof, said breech means having attached thereto a breech block to close off said opening, said breech means forming at its other end at least one aperture that communicates with the interior of said plenum chamber, a cartridge case insertable through said first end of said cartridge breech means, said cartridge case having a solid propellant charge disposed therein, the cartridge case having a first end containing a percussion cap and a second nozzle-containing end communicating with the interior of said plenum chamber through said other end of said cartridge breech means, a firing mechanism means adjacent said percussion cap for igniting said propellant charge when said cartridge case is enclosed within said breech means, and a fine mesh screen juxtaposed between said solid propellant charge and said nozzle-containing end, said screen serving to block the residue from burning propellant when said propellant charge is ignited.
