    • PROBLEM TO BE SOLVED: To provide a torque converter for sustaining the defoaming effects of a defoaming agent to reduce the worsening of fuel consumption due to an increase in the stirring resistance by preventing the accumulation of the defoaming agent in working oil. SOLUTION: The torque converter includes a pump impeller 1 having pump impeller blades 12 rotated around its axis with the input of torque, a turbine runner 2 arranged coaxially with the pump impeller 1 in mutually opposed relation, and a stator 3 for straightening the flow of the operating oil O from the side of the turbine runner 2 to the side of the pump impeller 1, and transmits torque between the pump impeller 1 side and the turbine runner 2 side. An outer peripheral portion Q of the pump impeller blade 12 is provided with a smooth portion 5 formed of a fluororesin. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:提供一种用于维持消泡剂的消泡效果的变矩器,以通过防止消泡剂在工作油中积聚而减少由于搅拌阻力的增加而引起的燃料消耗的恶化。 解决方案:变矩器包括:泵叶轮1,具有泵叶轮叶片12,其具有以其扭矩输入的方式围绕其轴线旋转;涡轮机转轮2,其与泵叶轮1以相互相对的关系同轴配置;以及定子3,用于矫直 将工作油O从涡轮转轮2的一侧流向泵叶轮1的一侧,并且在泵叶轮1侧与涡轮转轮2侧之间传递转矩。 泵叶轮叶片12的外周部分Q设置有由氟树脂形成的平滑部分5。 版权所有(C)2011,JPO&INPIT
