Device for dispensing an additive

摘要

The invention relates to a device for dispensing a liquid additive into a fuel circulation circuit for an internal combustion engine, comprising a reservoir (12) of liquid additive allowing an additive to be distributed into the fuel circulation circuit by means of a distribution line (16), characterized in that it comprises an additive chamber (22) in communication with the fuel circulation circuit and at least one wall (32) that is mobile and fluidtight between said additive chamber and the additive reservoir which, on the one hand, provides a fluidtight division and, on the other hand, maintains equal pressure between the additive in the additive reservoir and the fuel in the additive chamber.

1. A device for dispensing a liquid additive into a fuel circulation circuit for an internal combustion engine, said circuit assuring in a vehicle the circulation of fuel between the interior of a fuel tank and the engine, said device comprising;
an additive distribution line, a reservoir of liquid additive which allows releasing an additive into the fuel circulation circuit by said distribution line, an additive chamber in communication with the fuel circulation circuit, and at least one mobile and fluidtight wall between said additive chamber and the additive reservoir which, on the one hand, provides a fluidtight division, and on the other hand, maintains equal pressure between the additive in the additive reservoir and the fuel in the additive chamber.
