    摘要： An axial plunger pump or motor of the type such that a valve plate having a suction port and a discharge port drilled therein is fixed to a casing in which a rotary shaft is mounted. A cylinder block having one end surface opposed to the valve plate is coupled to the rotary shaft. A plurality of bores whose one ends can be communicated with the suction port and the discharge port are drilled in the cylinder block in parallel to the rotary shaft. A plurality of plungers, which can reciprocate within the respective bores in accordance with rotation of the rotary shaft are slidably fitted in the bores on the side of the other ends. A seal plate positioned between the valve plate and the cylinder block and making slide contact with the valve plate is coupled to the rotary shaft. A plurality of bushes or bushings, each consisting of a thin-walled cylinder portion fitted in one end portion of the bore and capable of making tight contact with an inner wall surface of the bore as expanded in diameter by a high-pressure liquid within the bore and a flange portion butting against the seal plate, are interposed between the seal plate and the cylinder block. An urging member for bringing the flange portion of the bush into tight contact with the seal plate in cooperation with the high-pressure liquid is provided between the flange portion of the bush and the one end surface of the cylinder block.

    摘要： A stern tube bearing system of contra-rotating propeller includes an inner shaft having a rear propeller and an outer shaft having a front propeller, both shafts being rotated in opposite directions. A shaft center portion of the inner shaft is made hollow, a plurality of oil supply holes are bores radially in the inner shaft so as to pass therethrough perpendicularly to the outer peripheral surface thereof, and a plurality of rows of these oil supply holes are arranged in the longitudinal direction of the inner shaft, whereby seizing of the bearing owing to offset contact at its rear end caused by the propeller being overhung can be prevented.
