Abstract
A pressurization device for pressurizing an enclosure may include a container containing a pressurized fluid, a pin that is inserted into the container, an actuator, and a heating device operably coupled to the actuator. The actuator may initially hold the pin in a closed position and allow the pin to move to an open position, disengaging from the container when the actuator increases in temperature. The pressurized fluid may force the pin toward the open position to release the pressurized fluid from the container. The actuator may include a frangible hollow bulb configured to fracture at a pre-defined temperature. The pressurized fluid may be vented into the enclosure through at least one fluid passage in fluid communication between the enclosure and the container.
Claims20
A pressurization device comprising:
- a container containing a pressurized fluid;
- a pin that is inserted into the container;
- and
- an actuator that initially holds the pin in a closed position, and that allows the pin to move to an open position when the actuator increases in temperature, thereby disengaging from the container to release the pressurized fluid from the container.
A pressurization device for pressurizing an enclosure, the device comprising:
- a container containing a pressurized fluid;
- a pin that is inserted into the container;
- an actuator that initially holds the pin in a closed position, and that allows the pin to move to an open position, disengaging the pin from the container when the actuator increases in temperature, wherein the pressurized fluid is released from the container and vented into the enclosure through at least one fluid passage in fluid communication between the container and the enclosure;
- and
- a heating device operably coupled to the actuator.
A method of pressurizing an enclosure, the method comprising:
- holding a pin in a container with a temperature sensitive actuator, wherein the pin is inserted in the container to contain a pressurized fluid;
- and
- disengaging the pin from the container when the temperature sensitive actuator increases in temperature, wherein the pressurized fluid is released from the container to pressurize the enclosure.
