Abstract
A fluid rotary machine includes first and second bodies and that are rotatable relative to each other. The second body is inside the first body to define a working fluid space there between. In addition, the machine includes a plurality of gates. Each gateis supported by the first body and is movable in a radial direction with respect to the first and second bodies to extend into and retract from the working fluid space. The machine also includes a magnetic gate control system configured to exert control of the motion and/or position of the gates in the radial direction. The magnetic gate control system is a dispersed system including magnets or magnets and components made of ferromagnetic materials. The magnetic gate control system may be dispersed between the gates, and one or both of the bodies.
