ABSTRACT:
A coreless torque converter has a unique layout or arrangement of stator, pump impeller and turbine runner, in which at least one of these elements has a portion formed to have an axial dimension which is reduced to minimize an offset amount of a center of swirl generated by working fluid recirculating through the converter to provide a high torque ratio and improved efficiency.
