Abstract
A stator for use with a torque converter includes an inner annular shell, outer annular core, a plurality of stator blades and pressure-side fluid directing projections. The plurality stator blades are disposed around the inner shell in a spaced apart configuration and radially extend to the outer core. Each stator blade includes an inlet-side edge, an opposed outlet-side edge and opposed pressure-side and suction-side surfaces extending between the inlet-side and outlet-side edges. The pressure-side fluid directing projections outwardly project from the pressure-side surface in spaced relation to each other and each extend between the inlet-side and outlet-side edges. The fluid directing projections are configured to aid in redirecting torque converter fluid returning from a turbine and reducing fluid separation as the fluid interacts with the stator blades and associated fluid directing projections thereby increasing efficiency and performance of the torque converter.
