摘要
The lubricating oil changer is used esp. for motor vehicle engines. Spent oil is removed and oil is then rapidly charged through a probe tube inserted through dipstick hole. The small bore probe tube is connected to a valve block which ensures that new and old oil are not mixed. An oil suction line (9) is blocked while new oil is supplied. Air enters into the valve block through an air pipe (18). Air supply is blocked while new oil is charged. The valve block has an internal spring loaded working piston (14) for ensuring closing of appropriate channels within the valve block.
