Abstract: The invention relates to a valve comprising: at least three channels (2, 9, 11); a metering gate (12) pivotable in a first channel (2); a diverter gate (10) that can shut off a second (9) or third (11) channel; and an actuation device (15) common to the gates (10, 12), said actuation device (15) comprising at least one actuation wheel (16) for pivoting at least one of the gates (10, 12) and having at least a first configuration in which the metering gate (12) is in a reference position in which the diverter gate (10) does not shut off the second (9) or third (11) channel. The actuation device (15) is configured such that, while in the first configuration, the rotation of the actuation wheel (16) causes the metering gate (12) to pivot in a single direction of rotation from its reference position, independently of the direction of rotation of the actuation wheel.

Abstract: The invention relates to a valve comprising: at least three channels (2, 9, 11); a metering gate (12) pivotable in a first channel (2); a diverter gate (10) that can shut off a second (9) or third (11) channel; and an actuation device (15) for actuating the gates (10, 12), said actuation device (15) comprising an actuation wheel (16) for pivoting at least one of the gates (10, 12) and having at least a first configuration in which the metering gate (12) is in a reference position in which the diverter gate (10) does not shut off the second (9) or third (11) channel. The actuation device (15) is configured such that, while in the first configuration, the rotation of the actuation wheel (16) causes: the diverter gate to pivot substantially and the metering gate to pivot slightly; and, subsequently, the metering gate to pivot without the diverter gate pivoting.

Abstract: A valve (1), in particular for a combustion engine, comprising:—a body (2) in which the following are provided: a housing (8) in which at least one bearing is arranged, and a conduit (3) designed to be traversed by a fluid, and—a shutter (5) mounted pivoting in the body (2) by a pin (7) received with radial clearance in the bearing, the shutter (5) pivoting between:—an open position, and—a closed position in which it comes into contact with the body (2) via a first contact area of the shutter located on a first side of the pin (7) and via a second contact area of the shutter located on a second side of the pin (7) opposite said first side, the switching of the shutter (5) from the open position to the closed position being accompanied by a radial movement of the pin (7) in the bearing.
