Embodiment Construction

[0034] as in figure 1 As can be seen in the figure, the filling device 1 or the filling connection 1 according to the invention is arranged on the filling pipe 2 of the working fluid container 3 . In the described exemplary embodiment, the working fluid container 3 is designed as a urea container 3 for a urea solution as reducing agent for catalytic denitrification of exhaust gases in motor vehicles.

[0035]The working fluid container 3 can be configured as a one-piece extrusion-blow-molded plastic container. The filling tube 2 and the filling connection 1 can also consist of a thermoplastic material. The filling connector 1 and the remaining components described can also be produced by injection molding. In the exemplary embodiment, the entire arrangement including the filling connection 1 , the filling tube 2 and the working fluid container 3 is constructed in multiple parts. As described below, the filling connection 1 is designed as a filling head with a connection 4 f...

Abstract

The invention discloses a filling device (1) for a working fluid container (3) of a motor vehicle. The filling device (1) comprises a manhole connection (11) into which a dispensing valve (40) can be introduced for filling the working fluid container (3). The filling device (1) also comprises a compensation chamber (24) to which the access port connection (11) is fluidically connected. The connection (21) of the filling device (1) is arranged between the working fluid container (3) and the compensation chamber (24) and is fluidly connected to the working fluid container (3) and the Compensation chamber (24) described above. The filling device (1) is characterized in that the connection piece (21) extends into the compensation chamber (24); the connection piece (21) is arranged to face the access hole connection piece (11) and separated thereby; said connecting piece (21) is surrounded by said compensation chamber (24); and a dispensing valve (40) can be introduced into said connecting piece (21) through said manhole connecting piece (11) .

Description

technical field [0001] The invention relates to a filling device for a working fluid container of a motor vehicle, said filling device comprising: a manhole connection into which a dispensing valve can be introduced for filling the working fluid container; a compensation chamber , which is in fluid communication to the access port connection; and a connection, which is disposed between and in fluid communication with the working fluid container and the compensation chamber. Background technique [0002] The working fluid container may be a fuel container, a urea container for the SCR (Selective Catalytic Reduction) process or other automotive working fluid container. [0003] When filling a motor vehicle operating fluid container, for example using a dispensing valve, the operating fluid can flow out via the filling device, which is designed as a filling connection. When the valve is closed via the suction hole / closing hole on the dispensing valve, the pressure surge it gen...
