Abstract:
The present disclosure relates to a variable pressure vessel. The vessel includes a liquid chamber and a gas chamber and a moveable barrier therebetween. The vessel has a volume, a first stroke, and a second stroke. The liquid chamber and the gas chamber each have a variable volume that changes responsive to the first stroke and the second stroke. The gas chamber has an outer wall wherein at least a portion of the outer wall is thermally conductive and allows heat to transfer therethrough. Movement of the moveable barrier between the liquid chamber and the gas chamber causes the volume in the liquid chamber and the volume in the gas chamber to displace each other. The volume in the gas chamber plus the volume in the liquid chamber is generally constant and generally equals the volume in the variable pressure vessel.

Claim (Index 27):
The variable pressure vessel of  claim 1  wherein the liquid chamber and the gas chamber has an interface therebetween and the value of the heat transfer coefficient of the interface can be calculated\n K=[p 1 V 1 A\u0394T/\u03b4t stroke )] ln( p 1 /p 2 ) \n and in the process of gas compression p 1  is the initial gas pressure, p 2  is the final gas pressure after compression, A is the surface of the heat transfer, \u0394T is the difference between the initial and the final temperature, t stroke  is the time of the compression stroke, V1 is the gas volume at the start of the compression stroke, \u03b4 is the wall thickness, and in the process of gas expansion V 1  is the gas volume at the end of the expansion cycle, p 1  is the gas pressure at the beginning of the gas expansion, p 2  is the final gas pressure at the end of the expansion and the heat transfer coefficient of the material for the interface is greater than or equal to the calculated K.
