Title:
HYDRAULIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/084855
Kind Code:
A1
Abstract:
This hydraulic system comprises: a hydraulic device that comprises a casing, a cylinder block that has a plurality of first detected sections on an outer peripheral surface of a cylinder block body and at least one second detected section, a piston, a coordinating mechanism, and a sensor that is disposed at a position corresponding to the first detected sections and the second detected section and that outputs a first signal and a second signal, respectively, when the first detected sections and the second detected section pass during rotation of the cylinder block; and a determination device that, on the basis of output results output from the sensor, determines whether the cylinder block is a conforming product. The plurality of first detected sections are formed on the outer peripheral surface of the cylinder block body at prescribed first intervals in the circumferential direction, and the at least one second detected section is formed on the outer peripheral surface of the cylinder block body at a second interval, which differs from the first intervals, from an adjacent first detected section in the circumferential direction.
