Abstract

A method is of diagnosing a hydraulic machine which includes a rotor shaft, a cylinder, a piston forming a working chamber together with the cylinder, and a high-pressure valve and a low-pressure valve provided for the working chamber, and which is configured to perform conversion between rotational motion of the rotor shaft and reciprocal motion of the piston. The high-pressure valve includes a poppet valve including a seat and a poppet configured to be in contact with the seat from a side of a high-pressure line of the hydraulic machine. The method includes: a step of measuring a pressure of the working chamber in a state where the high-pressure valve and the low-pressure valve are closed; and a step of detecting a damage of the high-pressure valve on the basis of the pressure of the working chamber.
