ABSTRACT:
An apparatus is disclosed for detecting leaks in a member defining an internal confined space. The apparatus comprises a housing, and induction means operatively connected to the housing for selectively inducing a partial vacuum therein, and valve means operatively associating with the housing and selectively movable to positions permitting pneumatic communication between a source of compressed air and the housing and between the induction means and the confined space, with the valve means further being selectively movable to a closed position by forces generated within the housing such that the valve means seals off pneumatic communication between the confined space and the induction means to maintain the partial vacuum produced in the confined space so as to enable the measurement and monitoring of the confined space for fluidic leaks by observing the vacuum pressures therein.
