Abstract
An apparatus for compressing a fluid has a linear compression chamber with a fluid inlet and a fluid outlet. A displacement assembly is spaced from the linear compression chamber and is actuable to engage the linear compression chamber and displace a working fluid linearly in the linear compression chamber to decrease the volume of a fluid in the linear compression chamber.
Claims31
An apparatus for compressing a fluid comprising:
- a linear compression chamber having a fluid inlet and a fluid outlet;
- and
- a displacement assembly spaced from the linear compression chamber and actuable to engage the linear compression chamber and displace a working fluid linearly in the linear compression chamber to decrease the volume of a fluid in the linear compression chamber and thereby increase the fluid pressure in the linear compression chamber.
An apparatus for compressing a fluid comprising:
- a linear compression chamber having a fluid inlet and a fluid outlet;
- and
- a compression assembly actuable to engage the linear compression chamber and decrease the volume of the linear compression chamber from an initial chamber volume to a discharge volume prior to discharge of fluid through the fluid outlet.
An apparatus for compressing a fluid comprising:
- a cavity defined in a chamber body and extending longitudinally along a linear axis from an inlet to an outlet of the chamber body;
- a flexible diaphragm extending across the cavity for a length of the chamber body, the flexible diaphragm and cavity defining a compression chamber;
- and
- a plurality of pistons actuable to engage the flexible diaphragm.
A method of compressing a fluid comprising:
- filling a linear compression chamber having a fluid inlet and a fluid outlet with a fluid to be compressed;
- progressively compressing the linear compression chamber to decrease the volume therein;
- and discharging the fluid from a discharge end through the fluid outlet of the linear compression chamber when a selected volume ratio is reached in the chamber.
A fluid compression process comprising:
- providing a linear compression chamber having a fluid inlet and a fluid outlet;
- closing the fluid outlet to prevent flow therethrough;
- filling the compression chamber with a fluid;
- creating a compression pocket filled with the fluid in the compression chamber;
- compressing the compression pocket in the compression chamber to decrease the volume of the compression pocket in the compression chamber;
- discharging the fluid through the fluid outlet when the volume ratio in the compression pocket is at a selected volume ratio;
- and
- continuously repeating the filling, creating, compressing and discharging steps.
