Abstract

PURPOSE: To quickly, automatically and completely change lubricating oil, by utilizing the pressure of discharged air from a blower only by operation simpler than ordinary operation without lifting up the blower and pipes.
CONSTITUTION: When three-way valves 15, 17 are set as shown by the solid lines and a shut-off valve 13 is opened, a part of compressed air flowing in a discharge pipe 8 is introduced into a first pipe 12 and enters into a gear chamber 6 through the shut-off valve 13 and the three-way valve 15, thereby pushing out used oil from the gear chamber to a used oil tank 19 through a second pipe 16, the three-way valve 17 and an ejector 22 while the oil is mixed with the air. When the three- way valves 15, 17 are shifted to the states as shown by the dotted lines in Fig., the compressed air is stopped from flowing into the gear chamber 6 and new oil spontaneously flows down from flowing into the gear chamber 6 and new oil spontaneously flows down from a new oil tank 18 to the gear chamber 6. Simultaneously the air in the gear chamber 6 is discharged to the used oil tank 19 through a pipe 12, the three-way valve 15, a branch pipe 23, the pipe 16 and the ejector 22.
