Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
195 words
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.
Claim 2
Dependent Claim
195 words
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.
Claim 3
Dependent Claim
37 words
A combination according to claim 1 wherein said valve operating element and said second element are located in said neck of said vessel and said third element is a manually rotatable element forming part of said mounting.
Claim 4
Dependent Claim
79 words
A combination according to claim 2 wherein said coupling is formed by a ring of depressions on one of said valve operating element and said control member, said depressions facing axially of said neck of said vessel when said vessel is locked in said mounting, and detent elements on the other of said valve operating element and said control member, said detent elements being engageable with said depressions, and spring means urging said detent elements axially into said depressions.
