Abstract
(EN)
An atmospheric vent structure for an expansion tank for a liquid reducing agent, the atmospheric vent structure being capable of preventing the liquid reducing agent from leaking from an atmospheric vent hose. A structure for venting to the atmosphere the inside of main tank (10x) and a sub-tank (10y) which form an expansion tank (10B), contain a liquid reducing agent (5), and are interconnected by a communication pipe (11), the venting being performed by atmospheric vent hoses (12x, 12y) provided to the tops (13) of the main and sub-tanks (10x, 10y). The atmospheric vent hoses (12x, 12y) are respectively provided with extending sections (f) which each extend from the top (13) of one of the tanks to the top (13) of the other tank, the extending section (f) having extending from the front end thereof a hanging section (g) which is bent downward so as to extend along a side surface of the other tank.

L'invention concerne une structure d'aération atmosphérique pour un réservoir d'expansion pour un agent réducteur liquide. La structure d'aération atmosphérique permet d'empêcher que l'agent réducteur liquide ne fuie d'un tuyau d'aération atmosphérique. Il s'agit d'une structure pour aérer vers l'atmosphère l'intérieur d'un réservoir principal (10x) et d'un réservoir secondaire (10y) qui constituent le réservoir d'expansion (10B), contiennent un agent réducteur liquide (5), et sont reliés entre eux par un tuyau de communication (11). L'aération est effectuée par des tuyaux d'aération atmosphérique (12x, 12y) disposés sur le dessus (13) du réservoir principal (10x) et du réservoir secondaire (10y). Les tuyaux d'aération atmosphérique (12x, 12y) sont munis chacun de sections d'extension (f) qui s'étendent chacune depuis le dessus (13) de l'un des réservoirs jusqu'au-dessus (13) de l'autre réservoir, et la section d'extension (f) présente, à son extrémité frontale, une section suspendue (g) s'étendant depuis celle-ci, qui est recourbée vers le bas de manière à s'étendre le long d'une surface latérale de l'autre réservoir.
