ABSTRACT:
A continuously variable hydraulic transmission composed of two variable displacement rotary vane pumps. Where the inner rotor of one pump is driven by the input shaft and the inner rotor of the other pump is held stationary by the supporting framework, both inner rotors sharing a common housing unit which rotates as the output shaft, and moves axially over the inner rotors to achieve inversely variable capacities of the two pumps and there-by varying the drive ratios between the input and output shafts. Two end plates are used, each of which rotates with its respective rotor and also moves axially with the housing unit to facilitate the variableness of the two pumps. A separating plate is incorporated between the rotors and rotates with the housing unit to maintain proper fluid pressure containment.
