PROBLEM TO BE SOLVED: To extract engine oil without continuously operating a negative-pressure generator, and simply and easily extract engine oil by conveying a small-capacity tank close to a vehicle. SOLUTION: An engine-oil extractor includes a suction pipe 1, a bottom-detection alarm 2, an extraction-measuring part 3, a negative-pressure generator 4, and a storage tank 5. The suction pipe 1 is inserted in an oil-level-gauge insertion hole to locate the tip at the bottom of an oil-pan so as to suck the engine oil. The bottom-detection alarm 2 detects that the tip of the suction-pipe has come to the bottom of the oil-pan and informs the fact. The extraction-measuring part 3 is graduated, and has a capacity of holding the engine-oil for at least one-vehicle. The inside of the extraction-measuring part 3 can be held at negative pressure, and is provided with a drain-valve on the bottom face to measure and extract the suction amount of the engine oil. The negative-pressure generator 4 brings the inside of the extraction-measuring part 3 in the state of negative pressure. The storage tank 5 has on its top a coupling port to be coupled to the drain valve of the extraction-measuring part 3. The coupling port is coupled or separated to/from the extraction-measuring part. The storage tank 5 receives and stores engine oil discharged from the extraction-measuring part in the amount for several vehicles. COPYRIGHT: (C)2009,JPO&INPIT
