Embodiment Construction

[0033] figure 1 Shown is a box assembly 5 according to one embodiment of the invention.

[0034] The tank assembly 5 has a tank container 10 . The tank container surrounds the tank space 12 . A liquid 7 is stored in the tank space 12 , which fills the tank space 12 up to the liquid surface 8 . The air is located above the liquid surface 8 in the tank space 12 .

[0035] The box container 10 has a lower side 14 and an upper side 16 . The upper side 16 is here opposite the lower side 14 . This means in particular that, in a typical installation state, the tank container 10 is installed with the lower side 14 pointing downwards. This can relate, for example, to the normal road position of the motor vehicle.

[0036] Arranged underneath the box container 10 is a removal unit 18 , on which some of the components to be described below are arranged.

[0037] A swirl pot 20 is formed in the tank container 10 . The swirl pot has a swirl pot opening 22 on the upper side. The sw...

Abstract

The invention relates to a tank assembly (5) having a tank container (10), a swirl pot (20) and an eductor pump (30), wherein a nozzle (32) of the eductor pump (30) is arranged on an upper side (16) of the tank container (10) at a distance above a swirl pot opening (22) of the swirl pot (20).

Description

technical field [0001] The invention relates to a box assembly. Such a housing arrangement usually has a housing container which encloses a housing space. Background technique [0002] Such a tank assembly may eg be used for liquids, such as aqueous solutions or water. The aqueous solution can be, for example, a urea solution which is used in motor vehicles to reduce certain components in the exhaust gas. Water can be used, for example, to actively lower the combustion chamber temperature. [0003] It has been determined that in tank assemblies for aqueous solutions there are often problems when the tank assembly is used at temperatures where the aqueous solution or water freezes. This is already possible at temperatures of 0[deg.] C. or slightly lower, ie temperatures which, for example, are often reached or lower in winter in Central Europe. [0004] It is therefore known, for example, to provide a heating device in the housing assembly. Furthermore, it is known to pr...
