VARIABLE VOLUME RESERVOIR AND METHOD FOR ITS USE A pressurized fluid reservoir having a variable working volume includes a cylinder body having a fixed storage volume and a first inlet and exhaust structure for allowing a compressible fluid to enter and leave the cylinder. A second inlet and exhaust structure is also provided for allowing a substantially incompressible fluid to enter and leave the cylinder. A first charge mechanism pumps the compressible fluid into the cylinder. A second charge mechanism pumps the substantially incompressible fluid into the cylinder to reduce the cylinder fixed storage volume to a desired working volume into which the compressible fluid can be pumped by the first charge mechanism. |
