Probably a pressurized CO2 tank, similar to an inflatable life jacket but on a bigger scale.

Crank: The Boeing Maintenance Manual, Chapter 26-69-00, Description and Operation, says this about the slides. The slide/raft (in this case) uses stored gas pressure from a bottle in the pack to activate the 2 slide inflation pumps. These pumps induce ambient air at several times the volume of the stored gas bottle, into the slide to cause inflation. In other words, the gas bottle powers the inflation pumps, which then bring in ambient air to fill the slide. The bottles themselves don't have enough volume to fill a large slide/raft combination. The regulator on the bottle senses when the slide is almost full, and does port a small amount of bottle pressure into the slide to complete the fill process, and make the slide "tight." Of course, there are valves downstream from the inflation pumps to prevent the inflation air from returning to ambient, and overpressure valves to prevent overinflating the slide. Hope this answers your question. Regards,
