This study describes design of low pulsation type water hydraulic motor practicable under a radiation environment. Basic structure of the motor is radial piston type. Reciprocation of 4 pistons was changed to rotary motion by a cam mechanism. The cam is always interposed between 2 cam followers without a spring, and the opposite 2 pistons are connected. The cam shape was designed so that pulsation of the rotational speed and the torque might be zero with the constant flow rate of water supplied to the motor. A distribution valve to change water flow to each cylinder was also newly designed with consideration of low viscosity of water.
