The fluid directional control valve provides the successive communication between several tubes for tapping off fluids and a single tube. It comprises a fixed element 1 equipped with several channels 3 to 8 each one of which communicates with a different tube for tapping off, and a movable element 2 equipped, on the one hand, with at least one nozzle 9 and, on the other hand, with means capable of successively bringing this nozzle into communication with the channels of the fixed element. The nozzle 9 of the movable element 2 is rectilinear, of constant cross-section and of the same diameter as the channels 3, 4, 5, 6, 7 and 8 of the fixed element 1, these channels also being rectilinear and of constant cross-section. Means are provided for allowing the nozzle 9 of the movable element 2 to mate successively with each of the channels 3 to 8 so as to form, successively with each of them, a rectilinear and sealed passage of constant cross-section. <IMAGE>
