<p>The device for sampling a liquid in a reservoir comprises a test tube (1) to be connected to an intermediate element (17) for taking samples of the liquid. The test tube (1) comprises orifices (3, 6) and a cavity (2) wherein the sampled liquid can flow. The orifices can be closed or not by the action of a plunger (9) mounted in the test tube. The plunger (9) comprises bayonet apertures (12, 13) designed to co-operate with bayonet catches (14, 15) mounted in the lower part of an actuating rod (27) subjected to the action of a spring (32) and a releasing element (29). A sliding stopper (20) is mounted sliding in the test tube lower part.</p> |
