Beschreibung
Zusammenfassung:	A diagnosis system for 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, includes: a pressure sensor for detecting a pressure of the working chamber; and a damage detecting part for detecting the damage of the high-pressure valve on the basis of a result of detection obtained by the pressure sensor. The high-pressure valve is a poppet valve which includes a seat, and a valve body being a poppet to be in contact with the seat from a side of a high-pressure line of the hydraulic machine. The damage detecting part detects the damage of the valve body of the high-pressure valve on the basis of a maximum value of a pressure of the working chamber in each cycle of the reciprocal motion of the piston.
