<p>PROBLEM TO BE SOLVED: To easily perform the working of the piston storing bores, to reduce the working cost, and to provide a radial piston pump in which the length of the piston can be elongated. SOLUTION: This pump comprises plural storing bores 23 radially formed on one of the coaxially rotated driving shaft and housing, in such manner that they are penetrated in a radius direction through a center of a rotary shaft the pistons slidably and protruding and retractingy stored in the storing bores 23, and energized outward in the radius direction by the springs 31, and a cam 5a formed on an inner periphery of the housing around the driving shaft, and kept into contact with the pistons 29. Further a large diameter part 9a of a pump body having the storing bores 23, comprises a shaft center hole 25, and the penetrated storing bores 23 are respectively divided into two sections by a stopper 27 inserted into the shaft center hole 25.</p> |
