Title:
FLUID FLOW CONTROLLER
Document Type and Number:
WIPO Patent Application WO2002068826
Kind Code:
A3
Abstract:
A fluid flow controller and method of operation thereof are presented. The fluid flow controller may include a casing having a casing blade. The fluid flow controller may also include a rotor having a first rotor blade and a second rotor blade radially spaced from the first rotor blade. The rotor may be configured to rotate relative to, and preferably within, the casing such that the casing blade passes between the first and second rotor blades during use. Compared to conventional pumps or compressors, the present fluid flow controller may have an enhanced ability to accelerate (and possibly to subsequently pressurize) fluid flow. Thus, the need to use multiple stages may be reduced or eliminated.
