Abstract

PURPOSE:To supply oil to a bearing without increasing the capacity of an oil- feeding pump by supplying lubricating oil from a surplus line of a gas sealing oil supply device in case of emergency such as when a lubricating oil supply device stops supply of oil. CONSTITUTION:Supposing that normal oil pressure of an oil-feeding line 6 for a bearing is P0, and drop allowable oil pressure is P1, even if a bearing lubricating oil supply device 5 stops supply of oil, if oil of oil pressur P1 is secured in bearings 3A, 3B, the bearings 3A, 3B are kept from damage by a fire due to a stop of oil supply. Accordingly, if a throttle 7D is adjusted in such a manner that oil pressure on return side of an oil escape valve 7c is P1 in a gas sealing oil supply device 7, when the bearing lubricating oil supply device 5 stops supply of oil, the downstream of a check valve 11 in the oil-feeding line 6 is urgently supplied with oil of oil pressure P1 through a suprlus oil line 12 from the gas sealing oil supply device 7.
