ABSTRACT:
An inflation system with pneumatic assist for a life raft or other inflatable article includes a puncture pin that is mounted to a slideably mounted piston. The puncture pin makes a small initial puncture in the membrane of a gas cartridge to start a trigger flow of compressed gas from the cartridge. That trigger flow travels through a gas passageway formed in the puncture pin and enters a cylinder within which the piston is mounted, driving the piston toward the membrane. A primary membrane cutter is carried by the piston, and the primary membrane cutter bursts through the membrane and unleashes a high volume flow of compressed gas into the article to be inflated. In a second embodiment, the primary membrane cutter is integrally formed with the puncture pin.
