Abstract

PURPOSE: To quickly automatically change lubricating oil, by effectively using the pressure of discharged air from a blower only by the shifiting operation of a sluice valve and two three-way valves without lifiting up the blower and pipes.
CONSTITUTION: When only one three-way valve 13 is shifted to a direction as shown by the dotted line in Fig, and the sluidce valve 11 is closed, the compressed air flows out of a discharge pipe 8 through the three-way valve 13 and a branch pipe 12 as shown by the one-dot chain line in Fig. and pushes out the lubricating oil from a gear chamber 6 toward a used oil tank 17 through a pipe 14 and the other three-way valve 15 while the lubricating oil is mixed with the air. When the sluice valve 11 is opened and the three-way valve 15 is shifted to a position as shown by the dotted line in Fig., a vacuum is produced in the upper end bent part 12a of the branch pipe 12 by the air flow in the discharge pipe 8. Therefore, the air is discharged from the branch pipe 12, the gear chamber 6 and a pipe 14 as shown by the dotted arrow in Fig. As a resutl, new oil is quickly supplied from a new oil tank 16 into the gear chamber 6.
