Abstract
A torque converter is designed to control the torque capacity C and prevent a constant torque capacity C when the speed ratio E is in the middle to high operational range. The torque converter includes a bladed pump impeller driven by an internal engine, a bladed turbine runner in fluid flow relation with the pump impeller, and a bladed stator for redirecting fluid to produce a toroidal flow path of hydraulic fluid. The blades of the stator have an inlet portion facing the turbine runner and to which flows hydraulic fluid from the turbine runner, an outlet portion facing the pump impeller and discharging hydraulic fluid from the stator, a pressure surface disposed on one side of the blade between the inlet portion and the outlet portion, a suction surface disposed on another side of the blade, and a plate portion disposed near the inlet portion.
