The cartridge includes a body containing the air and a head closing the body. There is a filling channel, which connects the outside of the cartridge to the body and which includes a filling non-return valve preventing the air from exiting the body. The head includes an inflation channel, which connects the filling channel to the body and includes an inflation non-return valve preventing the air from exiting the body. An inflation organ is movably mounted on the inflation channel to permit opening of the inflation non-return valve.

Abrégé

The air-compressing device for a cycle has a crank set. The device includes at least one cartridge for storing compressed air, and a compressor, connected to the cartridge. The compressor includes a device for engaging with the crank set and a first and a second compression chamber, each chamber provided with an air piston. The device for engaging is connected to each piston and translatably drives the stroke of each piston so as to carry out compression in the respective chamber. The first chamber is connected to the second chamber so as to transfer the compressed air within the first chamber to the second chamber when compression is being carried out in the latter.
