Patent ID: 6993903

Claim:
A stator blade mounted in a torque converter consisting of an impeller which is attached to a crankshaft through a connecting member for integrally rotating with the crankshaft, a turbine which is rotated by the oil discharged from the impeller coaxially attached to a transmission shaft, and a stator which is attached to a fixed stator shaft through a one-way clutch for directing the flow of oil flowing back to the impeller from the turbine to the rotating direction of the impeller, the stator blade is comprised of: said stator blade ( 8 ) having two sections ( 8 ′, 8 ″) arranged at a predetermined spacing from each other, said stator blade ( 8 ) providing a space formed by said two sections ( 8 ′, 8 ″) of an inner ring ( 6 ) and outer ring ( 7 ), said space providing a function as a slot-shaped passage ( 15 ) which passes through from the pressure side being the upstream of the flow direction to the suction side being the downstream, and said slot-shaped passage ( 15 ) on the stator blade formed within the angle range of −5° to +40°, wherein the angle is formed by the center axis of the slot-shaped passage which bisects the predetermined spacing positioned at a predetermined position on the mean camber line and the line tangent to the design flow path at the outlet point of the turbine blade.
