Abstract

Improvements in the construction of devices for extracting samples in vacuum-operated apparatus, characterized in that each apparatus is provided with a fixed group capable of being permanently fixed to the apparatus in question, particularly in the bottom wall of the device. Means from which the samples are taken, and which contains a duct that houses a check valve whose movable element is intended to be maintained, even by itself, pressed against a sealed seat when the lower pressure exceeds a given small value of the pressure superior, that is to say, of the pressure that remains inside the cited medium; and a removable group, which contains a container for the reception of the sample, nozzle devices for establishing inside said container a lower pressure, than that existing in the aforementioned medium, a watertight nozzle device for coupling with the cited duct provided in the fixed group, and by means of which said movable valve element can be tightened en bloc or, as the case may be, released in relation to its sealed seat, in such a way that, after joining the groups, the said valve can be opened or sealed, actuated from the outside, to precipitate and, respectively, interrupt the descent of the liquid sample in the aforementioned container.
