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) opening into a common space; a metering gate (12) pivotable in a first channel (2); a diverter gate (10) pivotable between a position for shutting 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 actuating at least one of the gates and having at least a first configuration in which the metering gate (12) does not shut off the first channel (2) and 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 (10) to pivot substantially as the diverter gate (12) pivots slightly; and, subsequently, the metering gate (12) to pivot.

主权项

1. A valve 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; and a shared actuating device of the gates, 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 position in which it does not shut off 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:
according to a first phase, substantial pivoting of the diverter gate while the metering gate is only subject to slight pivoting, andaccording to a second phase after the first phase, pivoting of the metering gate to alter the passage section of the fluid in the first channel without the position of the diverter gate being modified.
