ES44952U - Device for exhaust gas testing (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Device for exhaust gas testing characterized in that it consists of a tubular rod made of transparent rigid material, in one of whose ends there is a hollow spherical head whose cavity contains a longitudinal oblong hole of the aforementioned rod, by which it freely slides a variable amount of mercury that, under the effects of the instantaneous air pressure acting against its lower surface exposed to it, can travel the entire length of said longitudinal hole until it reaches a maximum value at which the air pressure itself dislodges to the mercury of the semi-capillary column and, depositing it against the inner wall of the spherical head, freely escapes to the outside by a perforated nail, which, in the form of an internal appendix in the aforementioned sphere, hinders the exit of the mercury although it leaves the passage free of the air or gas that comes from the container whose sealing is to check and that reaches the chamber capillary referred after its entry by a fitting, secured thereto through a flexible tube and after passing through a longitudinally perforated central body whose orifice coincides with the center of a lower chamber provided in said capillary tube, in which a body of porous material that can be traversed by air or gas but not by mercury, which, in working position, can gravitate on said filter.
