ABSTRACT:
A novel oil changer designed to enable one to visually determine the extent of contamination or deterioration of oil in service in comparison with fresh oil prior to change thereof for the purpose of attaining highly economical oil consumption. The oil changer includes an oil contamination inspection tank adapted to be selectively placed into communication with an external oil sump and a waste oil reservoir for forced passage therebetween of used oil under the drive of a pneumatically driven pump, and a metering tank for storing and metering fresh oil to be delivered therefrom to said external oil sump and adapted to be selectively placed into communication with a fresh oil reservoir and said metering tank for forced passage therebetween of fresh oil under the drive of a reversible pneumatically driven pump. The inspection tank is provided with wipers for cleaning its interior surface from the outside thereof, whereas the inspection tank is provided with a graduated overflow pipe for metering the amount of fresh oil to be delivered therefrom, the pipe extending in a vertical direction with its upper end opened into the tank interior at an appropriate level and its lower end connected with said fresh oil reservoir. With the above arrangement of the oil changer, oil change can be continuously effected in a very speedy and safe manner so as to substantially reduce the service time required therefor.
