DEFINITION

Classification: 475/59

Impeller-turbine type fluid circuit in series with planetary gearing:

(under subclass 31) Subject matter wherein the fluid torque transmitting means comprises a plurality of coaxial bladed elements forming a fluid filled torus having an input and an output, and only a single power path extends between said fluid drive and the planetary gearing.

(1) Note. The fluid drive may include a lock-up clutch. [figure]
