<p>Refilling device for compressed-gas cylinders, with connection thread and valve, in particular for small gas cylinders. A cartridge holder serves to accommodate oxygen-releasing, sheathless cartridges (20), the oxygen of which can be transferred from the interior (19) of the cartridge holder into the compressed-gas cylinder. To achieve the object of allowing inexpensive refilling of commercially available compressed-gas cylinders with low oxygen losses, the cartridge holder, according to the invention, is designed as a pressure body (1) surrounding the cartridge (20) as closely as possible and closed all round. Furthermore, a mating thread (14) is provided for externally screwing the pressure body (1) onto the compressed-gas cylinder. Passing through the mating thread (14) is a compressed-gas passage (11) which serves to transfer the oxygen into the compressed-gas cylinder. <IMAGE></p> |
