Claim 0:
1. A system for pressurizing a fluid used to perform an operation of a machine, the system comprising:
a source of a pressurized first fluid; and
an accumulator in fluid communication with the pressurized first fluid, the accumulator containing a gas that is compressible in response to the pressurized first fluid, a second fluid flowable from the accumulator in response to the compressed gas to a machine to facilitate an operation of the machine,
wherein the accumulator comprises:
a body defining an interior cavity; and
a piston disposed in the interior cavity and movable therein, the piston dividing the interior cavity into a first segment in fluid communication with the pressurized first fluid, a second segment in fluid communication with the second fluid, and a third segment that contains the compressed gas,

wherein the interior cavity comprises:
a first portion defining a first cross-sectional size, the first cross-sectional size corresponding to a first cross-section that is perpendicular to a direction of movement of the piston within the interior cavity; and
a second portion opposite the first portion defining a second cross-sectional size greater than the first cross-sectional size, the second cross-sectional size corresponding to a second cross-section that is perpendicular to the direction of movement of the piston,

wherein the piston comprises a first end portion disposed in the first portion of the interior cavity, and
wherein the piston comprises a second end portion disposed in the second portion of the interior cavity.
