The present disclosure provides for an advantageous extinguisher or discharge assembly. In exemplary embodiments, the present disclosure provides for an improved hydro-pneumatic fire extinguisher or discharge assembly. More particularly, the present disclosure provides for an improved hydro-pneumatic fire extinguisher or discharge assembly that is configured and dimensioned to fire or release a fire fighting agent (e.g., a fluid and/or liquid based fire fighting agent) while the extinguisher/assembly is oriented in any position or angle relative to gravity.

1. A discharge assembly comprising: a housing having a body portion having a first end and a second end, the housing configured and dimensioned to be releasably mounted with respect to a vehicle or structure to allow a user to use the housing in a portable fashion both within or away from the vehicle or structure;an actuator within the housing, the actuator configured and dimensioned to fluidically separate the housing into a first chamber and a second chamber, the first chamber configured to house a liquid-based fire fighting agent and the second chamber configured to house a pressurized fluid;a first end member enclosing the first end of the housing and having an outlet in fluid communication with a first valve, the first valve configured to allow: (i) the first chamber to be filled with the liquid-based fire fighting agent, and (ii) at least a portion of the liquid-based fire fighting agent to be released via the first valve when actuated;an actuating member mounted with respect to the first valve, the actuating member configured to be manually or remotely actuated;a second valve in fluid communication with the second chamber, the second valve configured to pressurize the fluid housed in the second chamber;a nozzle in fluid communication with the first valve, the nozzle configured and dimensioned to: (i) discharge the fire fighting agent of the first chamber from the nozzle for fire fighting purposes after the actuating member has been actuated, or (ii) be fluidically and releasably mounted with respect to a spray assembly to allow the fire fighting agent of the first chamber to travel through the nozzle and to the spray assembly for fire fighting purposes after the actuating member has been actuated;wherein the housing includes an interior protrusion, the interior protrusion configured and dimensioned to allow the actuator to rest thereon prior to actuating the actuating member;wherein the pressurized fluid in the second chamber is pressurized to about 300 psi or less prior to actuating the actuating member,wherein the first valve is an on/off valve;wherein upon actuation of the actuating member, the actuating member causes the first valve to open, thereby allowing for the release of the liquid-based fire fighting agent from the first chamber and through the outlet and to the first valve, and the housed fluid pressure in the second chamber moves the actuator towards the first chamber, thereby forcing at least a portion of the liquid-based fire fighting agent out of the first chamber and through the first valve; andwherein at least a portion of the liquid-based fire fighting agent is forced out of the first chamber regardless of the position of the housing relative to gravity. 2. The discharge assembly of claim 1, wherein the body portion of the housing is substantially cylindrical; and wherein the housing further includes a top extension portion that extends: (i) above the body portion, and (ii) at least partially around the circumference of the substantially cylindrical body portion, the top extension portion including a handle slot and a gauge view hole. 3. The discharge assembly of claim 1, wherein the actuator is a traveling piston fabricated from aluminum or ultra high molecular weight polyurethane. 4. The discharge assembly of claim 1, wherein the first end member includes at least one first groove configured to house a first gasketing material that forms a seal between the first end member and the housing; and wherein the actuator includes at least one second groove configured to house a second gasketing material that forms a seal between the actuator and the housing. 5. The discharge assembly of claim 1, wherein the pressurized fluid is selected from the group consisting of compressed gas, air or nitrogen. 6. The discharge assembly of claim 1, wherein the actuator includes a recessed area configured to increase the volume of the second chamber. 7. The discharge assembly of claim 1, wherein the second valve is a Schrader valve; and wherein the first valve is a ½ inch NPT pressure-actuated ball valve. 8. The discharge assembly of claim 1, wherein the first chamber is configured to house about two gallons of the fire fighting agent prior to actuating the actuating member. 9. The discharge assembly of claim 1, wherein the actuating member is a pneumatic actuator. 10. The discharge assembly of claim 1, wherein the actuating member further includes a handle member, the handle member configured to allow a user to manually actuate the actuating member by rotating the handle member. 11. The discharge assembly of claim 1 further comprising an electric solenoid member in communication with the actuating member and in electrical communication with a switch and a sensor, the electric solenoid member configured to: (i) allow a user to actuate the actuating member by manually moving the switch, or (ii) actuate the actuating member when the sensor determines that a certain condition has been reached. 12. The discharge assembly of claim 1, wherein the actuating member further includes manual switching means, the actuating member configured to be manually actuated via the manual switching means; and wherein the actuating member is in electrical communication with sensor means, the actuating member configured to be actuated via the sensor means. 13. The discharge assembly of claim 1, wherein the nozzle is a quick disconnect nozzle. 14. The discharge assembly of claim 1, wherein the spray assembly is a spray ring, the spray ring including at least one spray nozzle. 15. The discharge assembly of claim 1, wherein the spray assembly is configured to be mounted with respect to the vehicle or structure. 16. The discharge assembly of claim 1, wherein the housing further includes a pressure release port; and wherein when the actuator is at the top of its stroke and positioned at or near the first end member at the first end of the housing, the pressure release port is uncovered, thereby allowing substantially any remaining pressurized fluid in the housing to release therethrough, which thereby forces substantially any remaining fire fighting agent in the first chamber out through the first valve.
