Mounting of pressure vessels
First Claim
1. A combination comprising:
- a valve, said valve comprising a valve seat and a valve closure member cooperating with said valve seat;
a pressure vessel for pneumatic fluids at pressures above 200 kilograms per square centimeter and a stationary mounting therefor;
said pressure vessel having a neck containing said valve; and
said mounting having a socket to receive said neck;
locking means for retaining said neck in said socket; and
means for controlling said valve, said valve control means comprising a valve operating element movable in directions which are axial of said neck when the vessel is locked in said mounting to operate said valve;
a screw thread coupling said valve operating element to a second element so that relative rotation between said valve operating element and said second element produces axial movement of said valve operating element; and
a coupling between said valve operating element and a third element which transmits rotational but not translational movement, and an operative connection between said valve operating element and said valve closure member;
whereby rotation of said third element produces axial movement of said valve operating element to move said valve closure member away from said valve seat.

Abstract
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.
