<P>PROBLEM TO BE SOLVED: To reduce a leakage amount and efficiently feed oil when feeding the high-pressure oil from a propeller shaft end part from the main ship to a servo cylinder at a propeller shaft other end side in an oiling device for a thruster. <P>SOLUTION: The oiling device is provided with an outer peripheral side oil supply/discharge passage 23 communicating to a servo cylinder chamber 12b at the rear of a piston 13 and an inner peripheral side oil supply/discharge passage 21 communicating to a servo cylinder chamber 12a through the oil passage continuously connecting a change shaft 14 and a shaft center part of the piston 13. An approximately cylindrical shape oiling distribution member 31 is mounted to the outer peripheral surface of other end part of the propeller shaft 8 in a floating state. The oiling distribution member 31 is provided with a second distribution oil passage which is communicated to two connection parts 31b which are connected to a pair of straight tube shape piping 32 for supplying pressure oil drooping from the main ship side and the outer peripheral side oil supply/discharge passage 23, and a first distribution oil passage communicating to the inner peripheral side oil supply/discharge passage, and one side connection hole part 31b is communicated to the first distribution oil passage, and the other connection hole part 31b is communicated to the second distribution oil passage respectively. <P>COPYRIGHT: (C)2007,JPO&INPIT |
