Embodiment Construction

[0057] figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 In other respects there are identically numbered components, so a general description of these figures will first be given here. Figure 1 to Figure 4 A vertical sectional view of a device 1 according to the invention is shown in each case. Figure 5 and Figure 6 A horizontal sectional view of the device 1 is shown. The devices 1 each have a tank 2 which has a tank wall 41 which delimits the inner space 3 . On the underside of the tank 2 , the tank wall 41 forms the tank bottom 15 . In the tank bottom 15 there is a tank opening 42 . A container 4 is inserted into said tank opening 42 , in which container there is a delivery unit 8 for delivering reducing agent from the storage tank 2 to the dispensing point 9 . The access point 9 is preferably a connector, to which a line or a hose can be connected, via which reducing agent can be conveyed from the access point 9 to an input point for the r...

Abstract

The invention relates to a device (1) for providing a liquid reducing agent, comprising a tank (2) having an inner chamber (3), and a container (4) arranged at least partially inside said inner chamber (3) of the tank (2). Said container (4) is surrounded on the outside, at least partially by a filter (5) having a filter surface (6) and a filter depth (7), and said container (4) contains a conveyor unit (8) which is configured to extract the reducing agent from the tank (2) through the filter (5) and to guide it to a receiving point (9) for the reducing agent.

Description

technical field [0001] The invention relates to a device for supplying a liquid reducing agent, which has a storage tank for the liquid reducing agent and a device arranged on the storage tank for conveying the liquid reducing agent from the storage tank to a user. Delivery unit for feeding reducing agent to the injector in the exhaust gas treatment system. Background technique [0002] More recently, for cleaning the exhaust gas of (mobile) internal combustion engines, exhaust gas treatment devices have been used more and more, which clean the exhaust gas of the internal combustion engine by means of a reducing agent supplied to the exhaust gas. Mobile internal combustion engines are used, for example, to drive motor vehicles. [0003] For example, selective catalytic reduction methods are known in which the exhaust gas of an internal combustion engine is purified of nitrogen oxides, wherein a medium for reducing nitrogen oxides is supplied to the exhaust gas. Such a medi...
