The chamber or reservoir is the power source of a spudgun. It is, along with the barrel, the only component found in all launchers.
In combustion cannons, the chamber contains the flammable fuel/air mixture, offten butane or propane from an aerosol can of deoderant or from direct injection of the gas from a cylinder. If injected from a propane cylinder it is usually connected to a meter with regulates exactly 4.02% fuel into the chamber (the perfect amount).
In a pneumatic cannon the chamber contains compressed gas, usually air or CO2, however if the sound barrier wishes to be reached then a lighter gas must be chosen, offten helium or hydrogen (hydrongen is not advisable as it is extreamly flammable). The chamber is connected to the barrel either directly or through a valve, to propel the projectile when the energy is released.
The chamber is often the part of the launcher that is subjected to the highest stress, and it's important that it is well constructed and offers a high enough pressure rating. It is also the part where the most accessories are connected, especially combustion launchers; they can have a multiple holes to accommodate spark gaps, chamber fans, fuel meters and for venting.
