Document Type and Number:
WIPO Patent Application WO/2022/014600
Kind Code:
A1
Abstract:
An oil supply apparatus 1 is provided with a flow path system 6 that cyclically supplies oil to an object 4 to be supplied with oil. A control unit 31 comprises a storage unit 31a in which a first abnormal pressure set value that varies depending on an oil supply temperature is stored. The first abnormal pressure set value is set lower as the oil supply temperature increases. When an oil supply pressure detected by an oil supply pressure detection unit 21 is lower than or equal to the first abnormal pressure set value corresponding to the oil supply temperature detected by an oil supply temperature detection unit 22, the control unit 31 executes an abnormal shutdown of the object 4 to be supplied with oil.
