Abstract:
1. A downhole tool, the tool comprising: a central element having a rotor profile disposed thereon; a first sleeve rotatably and orbitally disposed around the central element, the first sleeve rotates around the central element responsive to fluid flowing through the downhole tool and has a stator profile disposed on the inside thereof to cooperate with the rotor profile to force the sleeve to rotate and orbit around the central element as fluid flows through the downhole tool; a second sleeve rotatably and orbitally disposed around the central element, the second sleeve has a stator profile disposed on the inside thereof to cooperate with the rotor profile to force the second sleeve to rotate and orbit around the central element as fluid flows through the downhole tool; an outlet disposed in a central portion of the central element to permit fluid to flow from a passageway disposed through the central element to an annulus area disposed between the central element and the sleeves; a first radial opening disposed in the first sleeve to permit fluid to flow from the annulus area to outside of the downhole tool; and a second radial opening disposed in the second sleeve to permit fluid to flow from the annulus area to outside of the downhole tool.
