DEFINITION

Classification: 475/35

Single impeller-turbine type fluid circuit divides or combines plural power paths:

(under subclass 31) Subject matter wherein the fluid torque transmitting means comprises at least three coaxial bladed elements forming a fluid filled torus, said elements being mechanically connected in power transmitting relationship to other parts of the drive train*.

(1) Note. Normally the circuit includes an input element, or pump, and two or more output elements, or turbines. There may be additionally included one or more reaction elements, or stators, which function to redirect or guide the fluid within the circuit and thus change the transmitted torque, or a turbine may fulfill the function of both turbine and stator.
