Energy recovering flow control valve
First Claim
1. A fluid flow control valve, comprising:
- a housing; and
a spherical obstructer comprising;
a through hole,wherein said spherical obstructer is inserted in said housing, andwherein said spherical obstructer is adapted to rotate therein about a first axis of rotation between a first position, in which said through hole is substantially coaxial to said control valve to allow the passage of a fluid, and a second position, in which said through hole is substantially transversal to said control valve to prevent the passage of the fluid, andwherein said control valve further comprises a rotor within said through hole,wherein said rotor comprises a shaft and a plurality of blades which are secured to said shaft,wherein said rotor is adapted to rotate in a continuous manner under the action of the fluid flowing through said control valve, said rotor rotating about said shaft having a second axis of rotation substantially coinciding with said first axis of rotation of said spherical obstructer.

Abstract
A fluid flow control valve (101, 601) includes a housing (106) and a spherical obstructer (107) having a through hole (108), wherein the spherical obstructer (107) is inserted in the housing (106) and is adapted to rotate therein (106) about an axis of rotation (110) between a first position, in which the through hole (108) is substantially coaxial to the control valve to allow the passage of a fluid, and a second position, in which the through hole (108) is substantially transversal to the control valve to prevent the passage of a fluid. The control valve further includes a rotor (111) within the through hole (108), wherein the rotor is adapted to rotate in a continuous manner under the action of a fluid flowing through the control valve, rotating about a second axis of rotation (112) substantially coinciding with the axis of rotation of the spherical obstructer.
