Abstract
A product having primary and secondary air chambers is tested for leaks by pressurizing such chambers to substantially different pressures from a common supply air source. Subsequent to charging the chambers to the predetermined pressures, any air flow occurring from the supply air source is indicative of a product leak. Secondary air is supplied to the product secondary air chamber through an electrically operated valve provided with signals by a transducer which senses the pressure in the secondary air chamber.
