ABSTRACT:
A gas generating apparatus for emergency refuge implements includes a gas generator body, a gas cartridge arrange in the gas generator body, a firing pin disposed opposite to the gas cartridge in the gas generator body, and a slider disposed slidably in the gas generator body. A movable ball-shaped pin is inserted through an opening formed in the gas generator body into an arcuate recess formed in the slider to maintain the slider at a standstill position. A pulling rope with a knob is connected to the movable ball-shaped pin to release the movable ball-shaped pin from the arcuate recess of the slider. A spring always presses the slider. When the movable ball-shaped pin is released from the arcuate recess of the slider, the firing pin and the gas cartridge are impacted to each other by moving the slider due to the pressure of the spring, thus to discharge the gas from the gas cartridge.
