TWO-WAY METERING DEVICE AND APPLICATIONS OF SAID METERING DEVICE

摘要

The invention relates to a double metering device for metering a fluid of an internal combustion engine, said metering device comprising a body in which are arranged a first (3) and a second (4) fluid circulation path for said fluid, in which paths first and second mobile shut-off shutters are positioned in order to meter the flow rate of fluid passing along said paths (3, 4), said metering device further comprising a motor that actuates said shutters and a drive train able to actuate the first shutter and/or the second shutter in response to actuation of said motor. According to the invention, the drive train is configured so that over a first operating range (30) it meters the flow rate passing along the first outlet path (3) by actuating the first shutter, the other shutter being held in the open position.
