Abstract
A hydraulic power transmission, such as a torque converter, has a pump impeller and a turbine runner with inclined blades having edge portions bent to form right angle connections to shells and cores of the pump impeller and the turbine runner. The inclination of the blades relative to the shells and cores provide improved transmission performance while the bent connecting edges forming right angles with the shells and cores eliminate gaps and secondary flows from acute angles between between the blades and the shells and cores to reduce oil leakage and the occurrence of secondary flows caused by such gaps. These blades have ample strength without central strengthening ribs to eliminate secondary flows caused by such ribs.
