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.
Claims28
A variable pressure system for both the compression and expansion of gases comprising:
- a hydraulic cylinder having a variable working volume responsive to motion of a piston and, wherein the variable working volume of the hydraulic cylinder is increasing during a first stroke and the variable working volume of the hydraulic cylinder is decreasing during a second stroke;
- a gas tank;
- and
- a variable pressure vessel having a volume and being operably connected to the hydraulic cylinder and operably connected to the tank;
- wherein the variable pressure vessel includes:
- a liquid chamber having a variable volume that decreases responsive to the first stroke and increases responsive to the second stroke;
- a gas chamber having a variable volume that increases responsive to the first stroke and decreases responsive to the second stroke, the gas chamber having an outer wall wherein at least a portion of the outer wall is thermally conductive and allows heat to transfer therethrough;
- and
- a moveable barrier between the liquid chamber and the gas chamber, and wherein movement of the moveable barrier causes the volume in the liquid chamber and the volume in the gas chamber to displace each other and 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.
