Leak detector
First Claim
1. A leak detector for connection to an air supply, the leak detector being adapted to deliver vapour under pressure to a system for detecting leaks in the system, the leak detector comprising:
- a tank defining a fluid chamber for holding a quantity of fluid, the tank further defining an inlet and outlet;
a first conduit for delivering air from the air supply to the fluid chamber, the first conduit having a first end for attachment to the air supply and a second end received in the inlet, the second end of the conduit being positioned to direct a flow of air from the air supply into said fluid chamber against said fluid thereby generating a vapour; and
a second conduit for delivering the vapour from said fluid chamber to the system, the second conduit having a first end received in the outlet and a second end receivable in said system for delivering the vapour under pressure to said system for testing for leaks in the system.

Abstract
A leak detecting apparatus is provided that tests for leaks in closed systems 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 air 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 fog 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 fluid thereby making the fog easier to observe upon the application of white light to the fog.

11. A leak detector for connection to an air supply, the leak detector being adapted to deliver a vapour under pressure to a system for detecting leaks in the system, the leak detector comprising:
-
a housing defining a chamber, the housing further defining first and second openings;
a tank located in the chamber, the tank defining a fluid chamber for holding a quantity of fluid, the tank further defining an inlet and outlet;
a first conduit for delivering air from the air supply to the fluid chamber, the first conduit having a first end for attachment to the air supply and a second end received through the first opening of said chamber and through the inlet of the fluid chamber for delivering air from the air supply to the fluid chamber, the second end of the first conduit being positioned in the fluid tank to direct air against the fluid whereby a vapour is generated in the tank by contact of the air against the fluid; and
a second conduit located in the chamber for delivering vapour from said fluid chamber to the system, the second conduit having a first end received in the outlet of the fluid chamber and a second end received through the second opening of the housing for connection to the system;

20. A leak detector for delivering vapour under pressure to a system for detecting leaks in the system, the leak detector comprising:
-
a fluid tank defining a chamber therein, the fluid tank defining first and second openings;
a vapour producing fluid located in the fluid tank;
an air supply;
a first conduit for delivering air from the air supply to the fluid tank, the first conduit having a first end attached to the air supply and a second end received in the first opening of said fluid tank; and
A second conduit for delivering the vapour from said fluid tank to the system, the second conduit having a first end received in the second opening of the fluid tank and a second end receivable in said system.
