ABSTRACT:
A hydraulic transmission with infinitely variability comprising a pair of identical cages in mirror image configuration containing radial slots, radial and axial vanes within the slots and camming surfaces to reciprocate the radial and axial vanes over the rotation of the cages, a non-rotatable but axially slidable cylinder for forming chambers within the slots of the cages, one of the cages being the pump and the other the hydraulic motor, and provision to slide the cylinder to adjust differentially the volumes within the chambers and therefore the input to output torque speed ratios of the transmission.
