The device (10) comprises a hollow body (12) having: an inlet (14), which is able to receive a fluid flow; a plurality of outlets (16), which are able to expel the fluid flow; a plurality of valve seats (18), which are arranged crosswise in the body (12) and are in fluid communication with the outlets (16); and a shutter (20), which is mounted so as to rotate in the body (12) among a plurality of positions in which it is able to open and close the seats (18). The shutter (20) is substantially cup-shaped and has a lateral wall (24), which peripherally extends from the bottom wall (22), delimiting a central cavity (26), and ending in a top edge (28) that is axially open. The central cavity (26) is in fluid communication with the inlet (14) through the top edge (28) and the lateral wall (24) transversely obstructs the valve seats (18), having a transverse opening (30), which is able to establish a fluid communication between the central cavity (26) and a seat (18), when the opening (30) faces the seat (18). |
