Abstract (en)

[origin: EP2781744A2] It is intended to suppress generation of a skew phenomenon of a roller in a radial piston hydraulic machine. The radial piston hydraulic machine is provided with a plurality of pistons, at least one roller, a cylinder block including a plurality of cylinders configured to guide the plurality of pistons reciprocably along a radial direction, respectively, and a cam configured to contact each of the at least one roller. Each roller is provided for n pistons that are arranged along an axial direction of the hydraulic machine to share, n being an integer not less than two.
