Abstract
Variable volume chamber devices are disclosed. The chambers may be defined by the space between two complementary rotors. The volume of the chambers may vary as a function of the variation of relative rotational speeds of the two rotors.
Claims21
A variable volume chamber device comprising:
- a first axial member;
- a first rotor mounted on the first axial member, said first rotor having:
- a generally cylindrical peripheral wall spaced from the first axial member;
- a first fluid port extending through the peripheral wall;
- a central opening surrounding the first axial member;
- a front wall extending away from the first axial member to the peripheral wall, said front wall defining a boundary for the central opening;
- a second fluid port extending through the front wall in the proximity of the central opening;
- a first rotor fin extending from the central opening along the front wall to the peripheral wall;
- a second axial member that is co-axial with the first axial member;
- a second rotor mounted on the second axial member and disposed at least in part within the first rotor peripheral wall, said second rotor having:
- a rear wall extending away from the second axial member to the peripheral wall,
- a central hub extending away from the rear wall and disposed within the first rotor central opening;
- a second rotor fin extending from the central hub along the rear wall to a location proximal to the peripheral wall;
- two fluid passages extending through the central hub;
- a first variable-speed driver connected to the first rotor;
- and
- a second variable-speed driver connected to the second rotor.

A method of pumping or compressing a fluid, comprising the steps of:
- providing a fluid to a variable volume chamber defined at least in part by a first wall and a second wall, wherein the first wall and second wall are configured to rotate independently of each other about a common axis;
- rotating the first wall at a variable first angular rate during a period of time;
- rotating the second wall at a variable second angular rate during the period of time;
- and
- changing the variable volume of the chamber so as to push the fluid through a variable volume chamber outlet by changing the variable first angular rate relative to the variable second angular rate during the period of time.
