Abstract
To suppress a separation of working fluid from the vane surface during operation at and around a fluid coupling condition attained after a substantial completion of torque conversion, the aerofoil and the array of stator vanes of a torque converter for vehicles are arranged such that a pressure side leading edge area and a suction side trailing edge area of the vane respectively satisfy the following conditions based upon the parameters assumed in FIG. 2: EQU (D.sub.L -D.sub.LMIN)/D.sub.LSL .ltoreq.0.38(X.sub.L /S.sub.L -0.08).sup.1. 7 EQU (D.sub.T -D.sub.TMIN)/D.sub.TST .ltoreq.0.36(X.sub.T /S.sub.T -0.45).sup.1. 7
