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.

A compressible fluid reservoir having a variable working volume, comprising: a storage body having a fixed storage volume; a first inlet and exhaust means for allowing a compressible fluid to enter the storage body and to leave said storage body at a predetermined initial first pressure and at a fluid pressure substantially reduced from the initial fluid pressure; a second inlet and exhaust means for allowing a substantially incompressible fluid to enter and leave said storage body; a first charge means for pumping the compressible fluid into said storage body; a second charge means for pumping the substantially incompressible fluid into said storage body to reduce said storage body fixed storage volume to a desired working volume into which the compressible fluid can be pumped by said first charge means wherein the storage body stores the compressible fluid in the desired working volume at the predetermined initial fluid pressure approximately between 2,000 psi and 15,000 psi; and means for enlarging said storage body fixed storage volume in response to the substantially reduced fluid pressure.
