Abstract
A rotating plug (4) is installed in a body (1) and can be in different positions in which two lateral drillings come in front of the orifices corresponding to the body (1) or a sampling orifice (18) in front of which a flask is placed. The fluid to be sampled is circulated so that it fills a chamber (12) delimited by the rotating plug (4), and the rotating plug is then turned until one of its drillings is facing the sampling orifice (18) and a piston (11) delimiting the chamber (12) is pushed in to extract the required quantity of the sample. This device is simple and has an excellent seal.
