Abstract

The present invention discloses a filling device (1) for a motor vehicle operating fluid container (3). The filling device (1) comprises a mouth hole connection piece (11), into which a dispensing valve (40) can be introduced in order to fill the operating fluid container (3). The filling device (1) further comprises a compensation chamber (24) to which the mouth hole connection piece (11) is connected in fluid terms. A connection piece (21) of the filling device (1) is arranged between the operating fluid container (3) and the compensation chamber (24) and is connected in fluid terms to the operating fluid container (3) and the compensation chamber (24). The filling device (1) is distinguished in that the connection piece (21) protrudes into the compensation chamber (24), the connection piece (21) is arranged so as to face the mouth hole connection piece (11) and to be spaced apart therefrom, the connection piece (21) is surrounded by the compensation chamber (24), and a dispensing valve (40) can be introduced through the mouth hole connection piece (11) into the connection piece (21).

Claims

1. Filling device for an operating fluid container for a motor vehicle, comprising:

a mouth hole connection piece into which a dispensing valve can be introduced in order to fill the operating fluid container,

a compensation chamber to which the mouth hole connection piece is connected in fluid terms; and

a connection piece which is arranged between the operating fluid container and the compensation chamber and which is connected in fluid terms to the operating fluid container and the compensation chamber;

characterised in that the filling connection piece has the following features;

the connection piece protrudes into the compensation chamber;

the connection piece is arranged so as to face the mouth hole connection piece and to be spaced apart therefrom;

the connection piece is surrounded by the compensation chamber so that, when the operating fluid level in the filling device rises, the operating fluid level inside the connection piece is always higher than the operating fluid level in the compensation chamber; and

a dispensing valve can be introduced through the mouth hole connection piece into the connection piece.

2. Filling device according to claim 1, characterised in that the connection piece has at least one discharge opening, by means of which the connection piece is connected in fluid terms to the compensation chamber.

3. Filling device according to claim 2, characterised in that the discharge opening in the installation position of the filling device is arranged in the lower region of the connection piece which is located in the compensation chamber.

4. Filling device according to any one of the preceding claims, characterised in that the connection piece has at least one material recess which extends in an axial direction over at least a partial length of the connection piece which is located in the compensation chamber.

5. Filling device according to claim 4, characterised in that the material recess extends substantially over the entire length of the connection piece which is located in the compensation chamber.

6. Filling device according to claim 1, characterised in that the dispensing valve can be brought into direct contact with the connection piece.

7. Filling device according to claim 1, characterised in that the connection piece tapers in the direction of the operating fluid container.
