Abstract
PURPOSE: To perform collection of oil by utilizing gravity and increase its reliability in such a way that an oil reservoir is installed below an oil reservoir which is vacuumized, and oil from the vacuum oil reservoir can be collected into an oil reservoir in the atmosphere by pressure from oil column.
CONSTITUTION: Oil which has been fed from an oil reservoir 8 through an oil feeding pipe 11 to a seal ring 4 by a pump 7 fills the space made with a shaft 1, and it moves to a drain oil chamber 12 on the atmosphere side and to a preliminary vacuum chamber 13. Oil which has been collected in the drain oil chamber 12 on the atmosphere side passes through a drain oil pipe 14, and it spontaneously flows down into an oil reservoir 8 in the atmosphere. On another hand, oil which has been collected in the preliminary vacuum chamber 13 passes through a drain oil pipe 15 by gravity likewise, and it flows down into a vacuum oil reservoir 18 which has been exhausted air by a vacuum pump 6. The vacuum oil reservoir 18 and the oil reservoir 8 are communicated through an oil feeding pipe 19, and oil in the vacuum oil reservoir 18 moves to the oil reservoir 8 in the atmosphere by pressure due to oil column in the oil feeding pipe.
