Abstract: A gas supply device comprises a gas storage capsule seated by a pierceable, malleable closure disc that is crushed by a cap housing a valve member in an axial passage and typically making a fixed and permanent engagement with the capsule. The valve member is integral with or carries a forward disc-piercing needle and is able to be urged by application of a disc-piercing force to pierce the disc to release gas from the capsule. The valve member has a rearward end which is normally biased by a compression spring into a valve-closing engagement with an inner surface of the cap. The valve therefore closes if the disc-piercing force is withdrawn.
