Abstract
A spherical gear pump comprises a housing with a first longitudinal axis, a spherical seat, an inlet and outlet adjacent the seat, inlet and outlet passages communicating with the inlet and outlet and adapted for connection to a source of liquid and a liquid load. A hemispherical gear is rotatively mounted within the seat and includes a plurality of peripherally spaced radial gear teeth and a drive shaft for rotation about the first axis. A hemispherical cam is adjustably positioned within the spherical seat having an arc less than 180.degree., and radial cam surfaces facing the spherical gear. A plurality of separate symmetrical radial gear teeth are pivotally mounted within and between the teeth of the spherical gear with each separate gear tooth having a radial top wall centrifugally biased against the cam surfaces on rotation of the spherical gear and a bottom wall adapted for pivotal movements within planes passing through the first axis on rotation of the separate gear teeth over the cam surfaces.
