  • Patent number: 7014021
    Abstract: A fluid coupling transmits power from a drive side to a driven side by utilizing kinetic energy of fluid such as oil. The fluid coupling comprises a pump impeller (4) provided on a drive shaft (1), a turbine impeller (5) provided on a driven shaft (9), a housing (20) fixed to the pump impeller (4) and surrounding the turbine impeller, and a multiple disc clutch provided between a drive shaft side and a driven shaft side. The multiple disc clutch is operated to couple the drive shaft (1) and the driven shaft (9) mechanically so that the drive shaft and the driven shaft are rotated at the same rotational speed. Thus, the fluid coupling can improve a power transmitting efficiency because of no slip between the rotational speed of the drive shaft and the rotational speed of the driven shaft.

  • Patent number: 6725657
    Abstract: The present invention relates to a power transmission apparatus for transmitting power by utilizing kinetic energy of a fluid, such as a torque converter, a fluid coupling, or the like. In a power transmission apparatus for taking out kinetic energy given to a fluid for power transmission by a prime mover as rotational power, water is supplied as a working fluid to a coupling section comprising an impeller (10) and a runner (11), water is supplied as a lubricating fluid to lubricate bearings (8, 9) for supporting an input shaft (7) and an output shaft (16) which are connected respectively to the impeller (10) and the runner (11), and water is supplied as a working fluid in a hydraulic servo mechanism for controlling a scoop tube (14) for adjusting the amount of water in the coupling section.
