Abstract: 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.

Abstract translation: 本发明涉及一种用于计量内燃机的流体的双重计量装置，所述计量装置包括一个主体，该主体设置有用于所述流体的第一（3）和第四（4）流体循环路径，其中首先 并且第二移动关闭百叶窗被定位以便测量沿着所述路径（3,4）通过的流体的流速，所述计量装置还包括致动所述快门的马达和能够致动所述第一快门的传动系，以及 /或第二快门响应于所述电动机的致动。 根据本发明，传动系被构造成使得在第一操作范围（30）上，通过致动第一挡板来测量通过第一出口路径（3）的流速，另一挡板保持在打开位置。
