Abstract:
A torque converter comprising:an impeller having at least one impeller blade, having an annular shape, and being configured to rotate about a rotational axis; a turbine having an annular shape, disposed axially adjacent said impeller, and being configured to rotate about said rotational axis; and a stator having an annular shape, and being configured to rotate about said rotational axis, said stator comprising a stator carrier extending toward said rotational axis away from said impeller and said turbine, and at least one stator blade disposed between said impeller and said turbine, said stator blade provided on an outer peripheral face of said stator carrier, said impeller, said turbine, and said stator forming a fluid-actuating portion having toric form around said rotational axis and having a first inside diameter extending from said outer peripheral face of said stator carrier through said rotational axis, and an outer diameter extending from an outermost peripheral edge of said impeller blade through said rotational axis, a ratio of said first inside diameter to said first outer diameter being equal to or greater than 0.61.
