VALVE, IN PARTICULAR AN ENGINE CONTROL VALVE, EQUIPPED WITH A METERING GATE AND A DIVERTER GATE

摘要

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.

1. An engine control valve, comprising:
at least three channels opening into a common inner space; a metering gate pivotable in a first channel to vary the passage section of the fluid in the latter; a diverter gate pivotable between a position for shutting off a second channel and a position for shutting off a third channel; a shared actuating device of the gates (10, 12), the actuating device including at least one actuating wheel rotatable to pivot at least one of the diverter gate and the metering gate, the actuating device having at least one first configuration in which the metering gate is in a reference position in the first channel and in which the diverter gate is in an intermediate position in which it is not in the position shutting off the second channel or in the position shutting off the third channel, and the actuating device being configured so that the rotation of the actuating wheel while the actuating device is in the first configuration leads to the pivoting of the metering gate in a single and same rotation direction from its reference position, independently of the rotation direction of the actuating wheel.
