Abstract
A rotary machine such as a pump or turbine has a casing defining a space therein. A fluid channel is formed in the casing and has a plurality of first channel portions fluidically coupled a plurality of second channel portions. The first and second channel portions are separated by the space. A rotor is rotatably coupled within the casing and within the space. The rotor has a plurality of apertures therethrough positioned within the space. The apertures are adjacent to the channel to coupled the first channel portions to the second channel portions.
Claims48
A pump comprising:
- a stationary member having a fluid channel therethrough, said channel having a plurality of first channel portions fluidically coupled to a plurality of second channel portions, said first channel portions and said second channel portions having a space therebetween;
- and
- a moving member having a plurality of apertures therethrough is positioned within said space, said apertures fluidically coupling said first channel portion and said second channel portion,
- said plurality of first channel portions, said moving member having a direction of travel, said plurality of second channel portions and said apertures forming a continuous fluid path through the pump;
- each of said first channel portions and each of said second channel portions having a diffuser portion having a first cross-sectional area and a nozzle portion having a second cross-sectional area less than said first cross-sectional area,
- whereby fluid within the plurality of first channel portions and the plurality of second channel portions moves in the direction of travel through the plurality of first channel portions and the plurality of second channel portions.

A rotating machine comprising:
- a casing defining a space therein;
- a fluid channel formed in said casing having a plurality of first portions fluidically coupled to and alternating with a plurality of second portions, said first portions and the second portions separated by said space;
- one of said plurality of first portions and one of said plurality of second portions defining one of a plurality of stages, each of said stages having a diffuser having a first cross-sectional area located in a first portion and a nozzle having a second cross-sectional area less than the first cross-section area located downstream in the second portion, said stages disposed in series to form a continuous fluid path through the rotating machine;
- and
- a rotor rotatably coupled within the casing, said rotor having a plurality of apertures therethrough positioned within the space, said apertures being adjacent to said channel, said apertures fluidically coupling said first portion and said second portion, said rotor having a direction of travel,
- whereby a fluid within the fluid path moves in the direction of travel in the first portion and the second portion.
