The invention relates to a device for closing a fluid duct of a motor vehicle comprising: a fixed hollow housing (6) provided with an inlet (8) and with an outlet (10), and; a first rotor (12) provided with an inner channel (14) that can rotationally move in a continuous manner inside the housing (6), the first rotor (12) being able to alternately isolate the inlet (8) and the outlet (10) of the housing (6) or to place them in communication via the inner channel (14). According to the invention, the device comprises a second rotor (16) placed between the first rotor (12) and the housing (6), and means (24, 26) for varying in a controlled manner the angular position of the second rotor (16) relative to the housing (6), the second rotor (16) comprising at least one opening (18, 20) located at least partially in the extension of the inlet (8) or of the outlet (10) of the housing (6). |
