    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.

  • Patent number: 6487855
    Abstract: A torque converter includes a pump impeller, a turbine impeller, a stator impeller disposed between the pump impeller and the turbine impeller, and a free wheel which is interposed between the stator impeller and a stationary case and operable to lock the stator impeller in order to allow the stator impeller to bear a reaction force generated with the amplification of torque between the pump and turbine impellers. In this torque converter, a stator shaft connected to the stator impeller is disposed with its tip end being passed through a turbine shaft to protrude outside the turbine shaft. The free wheel is interposed between the tip end of the stator shaft and the stationary case. Thus, it is possible to reduce the diameter of the stator impeller and thus, the diameter of the entire torque converter, irrespective of the presence of the free wheel inhibiting the rotation of the stator impeller.

  • Patent number: 3955367
    Abstract: In a fluid clutch of the type comprising cooperating pump and turbine elements between which toroidal power-transmitting liquid vortices can be established, control of the clutch by an operator is effected by moving a baffle within the working chamber between a clutched position in which the vortices can be established and maintained, and a declutched position in which it is interposed in the path taken by such vortices and prevents their establishment and maintainence. The baffle is operative to produce the required de-clutching and clutching action by changing the operative volume of the clutch element in which it is mounted. In a preferred structure a radially-slotted annular baffle is mounted on a cylindrical sleeve slidable on the output shaft and moves within the turbine chamber toward and away from the pump element, the turbine vanes entering the slots in the baffle; a spring urges the sleeve and the baffle toward the clutch engaged position further from the pump element.
