A hot air leak sensor (12) for sensing jet engine bleed air leaks in an aircraft.

Reduction of air leakage and spillage points

According to the invention, air leakage may be avoided, whereby the periphery (34) of the throttle valve (24) is arranged at a separation from a passage (44) for the throttle valve shaft (20) in the throttle valve support (26).

Reduce air leakages and spillage points

Such approaches avoid persistent tissue leaks and their consequences such as fluid leaks and air leaks.

The present invention also prevents combustion air from leaking.

NOTE: Airflow EFI systems are very sensitive to vacuum leaks, and air leaks downstream of the airflow sensor.

Plug the leaks - Air leaks are a costly waste of energy and money

This air leakage barrier ensures that any air leakage pathway across the heat seal region is closed.

Any air leaks are detected by immersion in water and observation of bubbles, or by using a sonic probe.

Air leaks in a vacuum bag are detected using a leak detection film covering the inside face of the bag.

Finally, use an ultrasound leak detector to scan as much of the air-line footprint as possible, to determine the location and scope of air leaks.

A refrigerator with a shielding apparatus that reliably prevent defrosting hot air from leaking.
