It has become very important to improve hydraulic motor efficiency, especially in the low-speed ranges, for finer operation. From this point of view, this report aims to prbvide technical data to help improve swashplate-type axial piston motor performance, particularly concerning the leakage and oil film thickness fluctuation between the valve plate and cylinder. The factors on their fluctuation were experimentally examined, and improvement by using the pistons with forced lubrication holes and a crowning shaft was attempted. The results show that the fluctuation of the tilt angle of the cylinder and the azimuth of minimum oil film thickness depend mainly on change of the high-pressure -side piston's numbers, and that the leakage flow rate fluctuation is mainly caused by the accuracy of the motor shaft.
