Power transmission device

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.
