LUBRICATING DEVICE AND LUBRICATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an emergency lubricating device for a gas turbine engine (10) which enables the engine to continuously operate for a period of time as long as possible after a trouble of component parts of the device and loss of hydraulic pressure resulting from the trouble. SOLUTION: The lubricating device for the turbine engine (10) includes a reservoir (50) containing a lubricant (52) of a backup amount therein and equipped with a lubricant inlet (54) and a lubricant outlet (56). At the normal operation mode, the reservoir (50) receives the lubricant through the inlet (54) while emitting the lubricant from the outlet (56) at the normal flow rate. The device further includes a means for preventing the backup lubricant (52) from flowing reversely through the inlet (54) as well as for emitting the lubricant at a flow rate not higher than the normal flow rate at the time of abnormal operation such as a case where the pressure of the lubricant becomes extraordinarily low.
