Abstract
An oil transporting vaporizer for a smoke generating apparatus to generate smoke to be supplied to a closed system to be tested for leaks. In a preferred embodiment, the vaporizer includes a hollow tube that is manufactured from a high temperature, fire resistant, porous material (e.g., ceramic). The vaporizer stands in a reservoir of oil such that some of the porous tube is filled with oil from the reservoir. A heater wire surrounds the outside of the porous tube above the oil within the tube. A gas (e.g., air) is blown into the porous tube and towards the oil to cause a mixture of air and gas to move through the tube. Because of its porosity, the air/oil mixture permeates the tube in the vicinity of the heater wire so as to be vaporized into smoke when the heater wire is energized.
