Abstract:
A system having a variable diameter impeller device that is operable for reducing an energy consumption of a rotating fluid or gas pump by increasing said impeller diameter as a speed of said rotating fluid or gas pump increases and decreasing the impeller diameter as the speed decreases. An extendable vane mechanism is configured to move along an elongated curved or sloping slot, said movement along the elongated curved or sloping slot is operable for increasing and decreasing a diameter of the impeller device. A spring mechanism having a first end and a second end extends and retracts to dynamically increase or decrease a diameter of the impeller device.

Claim (Index 1):
A system comprising:\n an impeller device, in which said impeller device comprises a variable diameter impeller of a centrifugal pump, wherein said variable diameter impeller is configured to increase or decrease a flow of fluid from said centrifugal pump; a housing structure, wherein said housing structure is configured to enclose said centrifugal pump impeller device, and wherein said housing structure is further configured to surround said impeller device and contain said fluid; an extendable vane mechanism, in which said extendable vane mechanism comprises at least five or more extendable vanes, wherein said extendable vane mechanism is configured to extend outward to increase said fluid flow or retract inwards to reduce said fluid flow; a fixed vane mechanism, in which said fixed vane mechanism comprises at least five or more fixed vanes, wherein said extendable vane mechanism is configured to follow a contour of said fixed vane mechanism, and wherein said fixed vane mechanism is further configured to become an extension of said extendable vane mechanism; a first engagement means, in which said first engagement means comprises at least one of, a long threaded hollow or solid screw and a long threaded hollow or solid bolt, wherein said first engagement means is configured to connect said extendable vane mechanism to said housing and engage said extendable vane mechanism within an elongated curved slot; an opening portion disposed in each of said five or more extendable vanes, wherein said opening portion of each of said five or more extendable vanes is configured to allow fluid pumped through said centrifugal pump, to pass; an elongated slot implement disposed in said housing structure, in which said elongated slot implement comprises a curved or sloping slot, wherein said elongated curved or sloping slot is configured to engage said first engagement means, and wherein said extendable vane mechanism is configured to move along said elongated curved or sloping slot, said movement along said elongated curved or sloping slot is operable for increasing and decreasing a diameter of said impeller device; and a spring mechanism having a first end and a second end that extends and retracts, in which said spring mechanism is into engagement with said first engagement means and a second engagement means.
