The torque converter (1) includes a front cover (2), an impeller (3), a turbine (4), a stator (5) that regulates fluid flow from the turbine (4) to the impeller (3), and a stator support mechanism (6) that supports the stator (5) to be rotatable only in one direction relative to a fixed shaft.

摘要： An impeller shell 40a of a torque converter includes a main portion 41, a connection portion 42 and a stepped portion 43. The main portion 41 has a curved inner peripheral surface 41a carrying impeller blades, and is opposed to a turbine 5. The connection portion 42 has a cylindrical form larger in diameter than an outer periphery of the inner peripheral surface 41a, and is fixed to a front cover 3. The stepped portion 43 couples an end of the main portion 41 near an engine to an end of the connection portion 42 near a transmission. A corner portion formed of the inner peripheral surface 41a and a surface 43a near the engine has a radius set to 4 mm or less by preliminary forming by a press and subsequent finish forming by a press.

摘要： A stator 6 includes an annular inner shell 11, an annular outer shell 12 and blades 13. The outer shell 12 is arranged radially outside the inner shell 11. The blades 13 are formed between the inner shell 11 and the outer shell 12, and are arranged at a plurality of circumferentially aligned positions, respectively. Each blade 13 extends from the inner shell 11 to the outer shell 12 and thereby couples the outer peripheral portion of the inner shell 11 and the inner peripheral portion of the outer shell 12 together. A rate of change in cross sectional area of the blade changes at a position located radially outside the inner shell 11 at a distance in a range from 1/6 to 1/2 of a distance (r2-r1) between the outer peripheral portion of the inner shell 11 and the inner peripheral portion of the outer shell 12.

摘要： A stator blade 13 has a blade tip 14, a blade trailing edge 15, a back 16 and a face 17. The blade tip 14 is an edge of the peripheral surface of the stator blade 13 near the turbine. The blade trailing edge 15 is an edge of the peripheral surface of the stator blade 13 near the impeller. The back 16 is a portion of the peripheral surface of the stator blade 13 extending between the blade tip 14 and the blade trailing edge 15 and opposed to the impeller 4, and has a streamline section. The face 17 is a portion of the peripheral surface of the stator blade 13 extending between the blade tip 14 and the blade trailing edge 15 and opposed to the turbine 5, and is formed of a streamline portion 17a and a plane portion 17b located near the blade tip 14. The shape of the stator blade 13 is such that a capacity coefficient (Cf) of a torque converter is lower when a speed ratio (e) is 0, and thereby improving fuel consumption during idling.
