Claims

[Scope of utility model registration request]

A cylinder block that rotates eccentrically with respect to the cam ring is provided in the cam ring, a plurality of cylinders are radially bored in the cylinder block, a piston is slidably provided in each cylinder, and each piston is pivotally connected to one end of the shoe, and the other end of each shoe includes a static pressure pocket for introducing the liquid in the cylinder, a static pressure pad provided around the static pressure pocket, and a static pressure pad provided around the static pressure pocket. In a radial piston type hydraulic rotating machine, a radial piston type hydraulic rotating machine is provided with a sliding part having dynamic pressure pads provided before and after the pad, and the sliding part is configured to slide along the cam ring, which is perpendicular to the rotational direction of the shoe. A radial piston type hydraulic rotating machine, characterized in that the shoe width in the direction is shorter than the diameter of the piston.
