LEAK DETECTOR

摘要

A leak detecting apparatus is provided that tests for leaks in closed system s such as the air intake system of an internal combustion engine. The system connects to a conventional air supply that provides air under pressure. The air from the a ir supply is routed through a fluid tank where the air is directed against the fluid thereby generating fog. The fluid is preferably a mineral oil. The fog is routed out of the apparatus and is fed into the system for detecting leaks. Leaks are observed visually when the fo g escapes from cracks or fissures in the system being tested. In order to aid in the observation of the fog escaping from the leaks, a light reflective pigment is added to the flui d thereby making the fog easier to observe upon the application of white light to the fog.
