Closing plug for compressed gas cylinder

摘要

The closing plug has a valve for a compressed gas cylinder (1) with container tube (2), in the end sector (4) of which the plug (3) is fitted. A gas cushion (7) is enclosed by a sealing ring (5,15) to act pneumatically on a setting member. A supply channel (8) in the plug, projects from the cylinder, and is held by the valve device against the cushion pressure. A radial boring (9a,9b) projects out in the supply channel having an aperture (12) which is covered by the sealing ring at the circumference of the plug. A valve pin (10a,10b) projects into the supply channel with radial play, and can move longitudinally.
