Patent ID: 8459018

Claim:
A hydrodynamic torque ( 1 ) converter comprising: a pump ( 3 ); a turbine ( 4 ) driven by the pump; and, a stator ( 6 , 6 a , 6 b , 6 c ) disposed between the pump and the turbine and supported by a housing of the torque converter in one direction of rotation by a freewheeling clutch ( 7 ), the stator comprising a plurality of blades ( 8 , 8 a , 8 b , 8 c ) extending between an inner diameter of a stator hub ( 9 , 9 a , 9 b , 9 c ) and an outer diameter ( 14 ) of the stator ( 6 , 6 a , 6 b , 6 c ), wherein each blade has a concave profile ( 17 ) between a leading edge ( 11 ) and a trailing edge ( 12 ) at a pressure side and a convex profile ( 16 , 16 a , 16 b , 16 c ) at a suction side, wherein: the convex profile ( 16 , 16 a , 16 b , 16 c ) includes an overly-proportional camber relative to the concave profile ( 17 ) in a center portion (B) along a meridional length ( 13 ) between the leading edge ( 11 ) and the trailing edge ( 12 ); the blades ( 8 a ) at an inner diameter comprise a blade angle distribution with increased thickness in the center portion (B); and, the overly-proportional camber of the center portion (B) regresses to a proportional camber of the convex profile with increasing diameter.
