Connection adapter for gas bottle valves

摘要

A connection adapter designed for gas bottle valves has a clamp-like locking device. An actuating device moves a piston guide bushing axially relative to the locking device to move the bushing into a sealed position in which the bushing bears upon a complimentary shaped connecting element. The actuating device has a threaded sleeve inside which the piston guide bushing is centrally extended, the threaded sleeve and bushing being mounted so that rotation of the threaded sleeve moves the bushing axially without rotating the bushing. A non-rotating, sliding block may be interposed between an end of the bushing and the clamp mounting.
