Fire piston

A fire pump ( also pneumatic lighter, lighter compression or air lighter) is a device for generating fire, is strongly heated by compression in the air, so that a scale can be made ​​to glow.

It consists of a sealed at one end only hollow cylinder in which an air-tight closing piston can swoop with the help of a stick. Happens very quickly, so inflamed by the heat generated in the heat of compression under a piston attached to a bit of tick tinder fungus.

History

Around 1770, invented the pneumatic Dumontier lighter which however in Europe was not widely prevalent, there were already better methods of producing fire at this time. The pneumatic lighter is a lighter air, and is now realized in North Borneo and the Philippines with bamboo pipe. The theory is simple, but the creation of a fire in practice with the pneumatic lighter is rather difficult.

Technical Terms

Today is still based on the diesel engine this procedure. With him air is compressed so far that a sufficiently high temperature is reached at which ignites the injected diesel fuel.
