  • Hydraulic torque converter for automotive vehicle
    Patent number: 8820062
    Abstract: A hydraulic torque converter for a vehicle, that comprises an impeller (I), a turbine (T) and a reactor (R) with a coaxial axis (A), and respectively fitted with impeller (1), turbine (2) and reactor (3) vanes, each defined by an inner side edge (11;21;31), an outer side edge (12;22;32), a trailing edge (13;23;33) and a leading edge (14;24;34), wherein the trailing edge (13) of the impeller is separated by an axial distance d1 from the leading edge of the turbine, and the trailing edge of the turbine is separated by an axial distance d2 from the leading edge of the reactor, the d2/d1 ration being equal to or lower than 1.4.
