Abstract
Abstract An apparatus for use in the supply of cryogenic liquid incorporates a liquid injection nozzled located adjacent one end of a cylindrical chamber the nozzle being connected to the discharge outlet of an expansion valve connectible to a liquid storage tank. The nozzle is so arranged that its line of discharge has a circumferential component of direction with respect to the chamber. The chamber is formed with a liquid discharge opening on the axis of the chamber at the end adjacent the nozzle and with a vapour discharge opening at the other end. The entrance to the vapour discharge opening is located close to the axis of the chamber. The nozzle may be presented by a pipe curved in a helical curve.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
213 words
An apparatus for use in the supply of cryogenic liquid incorporating a chamber having a smooth cylindrical bore, a liquid injection nozzle located adjacent one end of said chamber and so orientated that its line of discharge into the chamber has a component of direction which is circumferential with respect to the cylindrical chamber, a liquid discharge opening at one end of said chamber adjacent said nozzle, and a vapour discharge opening at the other end of the cylindrical chamber, said nozzle being constituted by the open end of a pipe located within the chamber and curved in a helical curve so that the line of discharge of the nozzle has an axial component of direction directed towards the other end of the chamber in addition to its circumferential component of direction, said liquid discharge opening being coaxial with said chamber; said vapour discharge opening being presented by a pipe penetrating the wall of the chamber with its axis radial to the axis of the chamber, the open end of said pipe within the chamber being located close to the axis of said chamber, and an expansion valve having its discharge outlet connected to said curved pipe at the end remote from the nozzle and its inlet connectible to a liquid storage tank.
Claim 2
Independent Claim
213 words
An apparatus for use in the supply of cryogenic liquid incorporating a chamber having a smooth cylindrical bore, a liquid injection nozzle located adjacent one end of said chamber and so orientated that its line of discharge into the chamber has a component of direction which is circumferential with respect to the cylindrical chamber, a liquid discharge opening at one end of said chamber adjacent said nozzle, and a vapour discharge opening at the other end of the cylindrical chamber, said nozzle being constituted by the open end of a pipe located within the chamber and curved in a helical curve so that the line of discharge of the nozzle has an axial component of direction directed towards the other end of the chamber in addition to its circumferential component of direction, said liquid discharge opening being coaxial with said chamber; said vapour discharge opening being presented by a pipe penetrating the wall of the chamber with its axis radial to the axis of the chamber, the open end of said pipe within the chamber being located close to the axis of said chamber, and an expansion valve having its discharge outlet connected to said curved pipe at the end remote from the nozzle and its inlet connectible to a liquid storage tank.
Claim 3
Dependent Claim
71 words
An apparatus of claim 1 in which the connection of the outlet of the expansion valve to the control pipe is constituted by a pipe which follows a path which lies radially inwards from said curved pipe to the axis of the chamber then along the axis of the chamber to the end of the chamber remote from the nozzle and through said end of the chamber to the expansion valve.
Claim 4
Dependent Claim
36 words
An apparatus as claimed in claim 1 in which the curved pipe presenting the nozzle is fitted with spacers to hold it in position within the chamber a predetermined distance from the wall of the chamber.
