Power train with hydrokinetic torque converter

A fluid-operated hydrokinetic torque converter for use in a power train of a motor vehicle, comprising:

• a fluid-containing housing rotatable about a predetermined axis;
• means for connecting said housing to a rotary output element of a prime mover forming part of the power train;
• a rotary input element coaxial with said housing;
• means for transmitting torque between said housing and said input element along a first path including a pump disposed in and rotatable with said housing, a turbine disposed in and rotatable with and relative to to said housing and connected to said input element, and a stator disposed in said housing between said turbine and said pump as seen in the direction of said axis, said pump having an outer wall remote from said turbine and said turbine having an outer wall remote from said pump, as considered in the direction of said axis, said turbine and said pump and said stator together forming a torus having a width as measured radially of said axis and a length as measured in the direction of said axis and the ratio of said length to said width being at most 0.65;
• means for transmitting torque between said housing and said input element along a second path, including an engageable and disengageable lockup clutch;
• and
• control means including means for supplying fluid to said the torque converter.
