<p>A combination of a pressure vessel for pneumatic fluids at pressures above 200 kilograms per square centimeter and a stationary mounting therefor, the pressure vessel having a neck which fits into a socket in the mounting and is retained therein by a locking mechanism, for example, a bayonet coupling or a polygonal flange on the neck passing through an aperture of the same shape in a flange in the socket. The neck contains a valve and the combination includes a mechanism for controlling the valve. Such mechanism may be in the neck or in the mounting and preferably comprises an axially movable valve operating member mounted by an external screw thread in a second member and coupled to a third member, such as a manually operable knob, by a coupling which transmits rotation, but not translation.</p> |
