DEFINITION

Classification: 475/44

Stator rotatable in reverse direction to provide drive:

(under subclass 35) Subject matter wherein one of the coaxial bladed elements functions as a reaction member to modify the speed and direction of the fluid in the torque transmitting means in one mode of operation and also functions, when rotating in a direction opposite to an input element, of the fluid torque transmitting means to add torque to the drive train.
