<p>The invention relates to a regulator device for a sampler of a liquid flowing through a pipe (1), said sampler comprising a four-way distributing valve (4), a first way (7) being designed for connection to said pipe and a second way (8) being connected to a sample tank (9). Said distributing valve is furthermore controlled by the rate of flow of liquid in the pipe in order alternately to put the first way in communication with the third and the second way in communication with the fourth, and then the first way in communication with the fourth and the second way in communication with the third. The regulator comprises two outflow chambers (12, 13) that can be put in connection respectively with the third and with the fourth way of the distributing valve, and a regulator chamber (22) separated by a deformable diaphragm (21) from each of the outflow chambers, said regulator chamber being provided with means (26) for varying the volume of the outflow chambers by deformation of said diaphragms. <IMAGE></p> |
