ABSTRACT:
A fluid torque converter using a stator assembly adapted to be formed by a die assembly essentially consisting of two halves that can be separated apart in an axial direction when removing a formed stator assembly, a part of an inner circumferential surface of the core ring adjacent to a pressure surface of each of the stator blades is provided with a bulge. Owing to the bulges provided in the inner circumferential surface of the core ring adjacent to the pressure surfaces of the stator blades, the annular fluid flow can be conducted in smooth fashion, and flow separation can be avoided. As a result, the efficiency of the torque converter and the power response of the automatic transmission system can be improved while the stator assembly can be fabricated at a low cost by using a die assembly which can be drawn apart in the axial direction.
