摘要： Apparatus for exchanging waste oil with fresh oil in a device such as torque converter, based on a new finding that extracting waste oil from the pan thereof, supplying fresh oil thereinto and after the lapse of some pause time such extract and supply are repeated during said torque converter is kept to operate to circulate oil between the converter proper and the oil pan. The repetition of extract, supply and pause is automatically done according to the operation design stored in the computer with determining the total amount of extracted waste oil and fresh oil to be supplied.
