<P>PROBLEM TO BE SOLVED: To provide a seal oil feeding apparatus which simplifies the structure without impairing functions and circulates a seal oil smoothly without providing a new power source. <P>SOLUTION: A seal oil feeding apparatus includes an expanded tank 11, a float trap tank 12, and an air extraction tank 13. The expanded tank 11 recovers a seal oil S flowing from a seal device 4 into a housing 3 and accumulates the seal oil S. The float trap tank 12 is integrally formed with the expanded tank 11 so as to continue into the expanded tank 11 horizontally. The float trap tank 12 is in communication with the expanded tank 11, and the level of the seal oil S becomes substantially the same as the level of the oil seal S of the expanded tank 11. Further, the float trap tank 12 includes a built-in float valve 121. The air extraction tank 13 is installed at a position lower than the expanded tank 11 and the float trap tank 12 and accumulates the seal oil S flowed from the float valve 121. <P>COPYRIGHT: (C)2012,JPO&INPIT |
