Abstract

PURPOSE: To prevent the infiltration of oil vapor filled in a discharge oil passage of shaft sealing oil and a discharge oil reservoir into a stator, by mounting a portion, which is inverted and rises, on the way of the discharge oil passage.
CONSTITUTION: A U-shaped trap 11, which once falls, is inverted and rises, is installed on the way of a discharge oil passage such as a discharge oil pipe 6 reaching an extension tank 7 from a shaft sealing portion 4. It is suitable that the U- shaped trap 11 is disposed at locations that are near to the shaft sealing portion 4 as much as possible. Thus, the infiltration of oil vapor filled in the discharge oil pipe 6 and the extension tank 7 into a stator 1 is prevented by the static pressure of suction winds a, and the lowering of insulation resistance can be obviated.
