Abstract
The present invention is related to a blade of a stator, where a passage is formed in the blade of a conventional stator which constitutes a torque converter and thereby generates stable torque and prevents sag in the stall state and at low speed ratios. The present invention is characterized in that an oil flow passage is newly formed between the pressure side and the suction side of the blade of the stator. The present invention avoids the occurrence of flow separation and recirculation regions at low speed ratios through modification of the structure of the blade of the stator and thereby prevents performance deterioration and may improve the overall performance of the torque converter.
