ABSTRACT:
The technical field dealt with is that of fluid conveyance, and the invention relates to a device for selectively sampling fluid from two sections of a line which ensures great operating practicality and minimal dimensions. The solution consists of a device comprising a selecting element with a cavity associable with a syringe and comprising an appendix suitable for rotating in a seat of a fixed element to which converge three conduits, the two end conduits being connectable with the two parts of the line and the central conduit being connectable with a drain, said selecting element having two passages, each of which is suitable for establishing a communication between one of the end conduits and the central conduit, and a third intermediate passage suitable for establishing a communication selectively between the two end conduits and said cavity.
