Abstract
A spherical gear pump that comprises two rotors, or geared spheres, with the teeth arranged around them in a circular band at right angles to their axis of rotation: the pump spheres are covered by close-fitting spherical cases or housings except at the central or most internal part of the connection between the gears on the two spheres, the fluid contained in the cavity created between the most external gears and the case or housing is moved during rotation from the intake to the outlet, one sphere is driven by its shaft and the other is dragged by the gearing between the two.
Claims8
A gear pump comprising geared spheres, with teeth arranged around the geared spheres in a circular band at right angles to their axis of rotation, said teeth extending into at least one of said geared spheres, wherein said geared spheres are substantially covered by close-fitting case or housing having the inner surface equally distant from a center at all points except at a central or most internal part of the connection between said gears on said two spheres, and wherein fluid contained in a cavity created between said geared spheres and said case or housing is moved during rotation from an intake to an outlet.
