Abstract

A method of manipulating a fluid is performed by decoupling a first working chamber from a second working chamber. Each working chamber is provided by a rotary device which includes a stator and a rotor rotatabie with respect to the stator about an axis to manipulate the fluid. The rotor is rotated to establish a first fluid pressure within the first working chamber and to establish a second fluid pressure within the second working chamber, independent of the first fluid pressure. A controlled and intermittent mass flow of the fluid is delivered from the first working chamber when the first fluid pressure is established. The second working chamber is charged to an inlet fluid pressure. Decoupling provides that either one or both may be applied in compression or expansion as a stage leading to or exiting from combustion to raise pressure, lower temperature, or extract work from expanding fluid.
