種オイルに混入しないようにすることができる。According to the invention described in claim 1, when a large amount of one new oil used in the previous oil exchange remains in the new oil supply system, the residual new oil is recovered as much as possible. The remaining residual new oil is removed from the new oil supply system to the waste oil discharge system by another new oil at the time of the next oil change, so even if only one new oil supply system is used, It is possible to prevent the used oil from mixing with the different oil used in the next oil change.

とができる。According to the second aspect of the present invention, when the waste oil of the oil exchange target portion is relatively clean like the oil for the automatic transmission, the waste oil of the oil exchange target portion of the new oil supply system is used. Since the foreign oil adhering to the inner wall of the pipeline is washed and removed to the waste oil container, the oil used in the previous oil exchange does not mix with the foreign oil used in the next oil exchange even with one new oil supply system. You can

By removing the waste oil to the waste oil discharge passage that communicates with the new oil supply passage via the upper part of the The oil can be changed so that it does not mix with the different oil used in the next oil change. Further, since this device uses one new oil supply passage, it can cope with an increase in the number of new oil containers, and even if the oil remaining inside the new oil pump is mixed with different types of oil. Can solve problems.
