Abstract
A replaceable cartridge-type oxygen generator is described including a quick-opening pressure casing containing a chemical oxygen-generating cartridge having a severable hermetically-sealed container and an ignition device, the casing further including an actuating device capable of actuating the ignition device only when the cartridge is disposed within the casing and the casing is closed. The casing further includes a high-volume vent automatically effective in case of the sudden build-up of a high pressure, such as may be caused by the ignition of a contaminant. Also described is an oxygen supply system including a plurality of such generators connected to an outlet manifold having pressure sensing means controlling the ignition of the cartridges.
Claims25
A replaceable cartridge type oxygen generator, comprising:
- a quick-opening pressure casing including a main casing section, an openable casing section quickly openable and closable with respect to the main casing section, and sealing means sealing the two sections when closed together;
- a chemical oxygen-generating cartridge disposed within the casing, said chemical oxygen-generating cartridge having a severable hermetically sealed container and an ignition device for igniting the cartridge;
- an actuating device at least a portion of which is fixed to the casing so as to be cooperable with said ignition device to ignite the cartridge when the cartridge is in effective position within the casing, and a spring engageable by the cartridge and spacing same from said effective position to render the actuating device ineffective to actuate the ignition device except when the spring is compressed by the closing of the openable casing section on the main casing section.
A system for supplying oxygen, comprising a plurality of oxygen generators each including a pressure casing having a main casing section, an openable casing section, and sealing means sealing the two sections when closed together;
- means for receiving within the casing a chemical oxygen-generating cartridge having a severable hermetically sealed container and an ignition device for igniting the cartridge;
- an actuating device capable of actuating the ignition device only when the cartridge is disposed within the casing and the openable casing section is closed on the main casing section;
- and conduit means connecting said oxygen generators to an outlet manifold, the casing of each of said oxygen generators having a volume which is sufficiently greater than that of its cartridge so as to permit the interiors of all the casings to act as a common reservoir for the storage of oxygen generated by the generators.
A generator including a pressure casing having a main casing section, an openable casing section, and sealing means sealing the two sections when closed together;
- means for receiving within the casing a chemical oxygen-generating cartridge having a severable hermetically-sealed container and an ignition device for igniting the cartridge;
- an actuating device capable of actuating the ignition device only when the cartridge is disposed within the casing and the openable casing section is closed on the main casing section;
- said casing of each generator including an interlocking device effective to prevent opening of the openable casing section when the casing is pressurised.
