Abstract
Abstract The control valve has a stator which imparts a swirl to the flow of fluid and a rotor which is rotated under the swirl of fluid. Energy is absorbed from the rotor in various ways. In one instance, the rotation of the rotor is subjected to a drag force which is induced in opposition to the force of rotation in order to control the pressure drop in the flow. In another instance, the rotation of the rotor is used to store electrical energy which can be used for other purposes throughout the process system.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
160 words
In combination with a valve comprising a housing defining a passageway for the flow of a fluid, a stator mounted within said housing in the path of flow of thE fluid to impart a swirl to the fluid passing therethrough, a seat ring on said stator to define an aperture for passage of fluid out of said stator, a rotor rotatably mounted concentrically within said stator in the path of flow of the fluid for rotation under the flow of fluid passing therethrough, said rotor including a rotor shaft extending out of the plane of said stator, and a sealing disc on said rotor for mounting with said seat ring in a closed position of said rotor to seal said aperture; an electrical generator means mounted about said shaft to produce an electrical charge in relation to the torque of said rotor shaft; and an electrical storage device connected to said generator for storing electrical energy generated in said generator.
Claim 2
Dependent Claim
