## Abstract

The present invention relates to a filler head (100) for a liquid tank in a motor vehicle with a housing (103), with a first molded housing part (103-1) having formed therein a tank vent pipe (105) for introducing air into the housing (103); and a second molded housing part (103-2) having formed therein a dip tube (107) for guiding a jet of liquid in the interior of the filler head (100), the dip tube (107) including a vent opening (111) for discharging from the filler head (100) the air that may be introduced through the tank vent pipe (105).

## Claims

### Claim 1

A filler head for a liquid tank in a motor vehicle with a housing (103), with:
a first molded housing part having formed therein a tank vent pipe for introducing air into the housing; and
a second molded housing part having formed therein a dip tube for guiding a jet of liquid in the interior of the filler head, the dip tube including a vent opening for discharging from the filler head the air that may be introduced through the tank vent pipe.

### Claim 2 (depends on 1)

The filler head according to claim 1, wherein the vent opening of the dip tube is or comprises an opening of circular cross-section.

### Claim 3 (depends on 1)

The filler head according to claim 1, wherein the vent opening of the dip tube is arranged in the area of an upper housing wall.

### Claim 4 (depends on 1)

The filler head according to claim 1, wherein the dip tube is formed in the form of a cylinder.

### Claim 5 (depends on 1)

The filler head according to claim 1, wherein the dip tube comprises on an inner side thereof a spacer for creating a vent channel in the area of the vent opening.

### Claim 6 (depends on 5)

The filler head according to claim 5, wherein the spacer is formed by a spacer rib extending in the longitudinal direction of the dip tube.

### Claim 7 (depends on 6)

The filler head according to claim 6, wherein the spacer rib includes a stop for a filler nozzle.

### Claim 8 (depends on 7)

The filler head according to claim 7, wherein the stop in the spacer rib is arranged below the vent opening of the dip tube.

### Claim 9 (depends on 1)

The filler head according to claim 1, wherein the tank vent pipe extends parallel to the dip tube.

### Claim 10 (depends on 1)

The filler head according to claim 1, wherein the tank vent pipe is arranged in the vicinity of the vent opening of the dip tube.

### Claim 11 (depends on 1)

The filler head according to claim 1, wherein the second molded housing part has formed therein a surge wall, which is arranged between an outlet of the tank vent pipe and the vent opening.

### Claim 12 (depends on 1)

The filler head according to claim 1, wherein the dip tube comprises a modular, annular surge element, which is attachable to the dip tube.

### Claim 13 (depends on 12)

The filler head according to claim 12, wherein the modular, annular surge element is attached to the dip tube via an opening on an outer side of the dip tube.

### Claim 14 (depends on 13)

The filler head according to claim 13, wherein the modular, annular surge element is fixed by a stop formed by longitudinal ribs positioned on the outer side of the dip tube.

### Claim 15 (depends on 13)

The filler head according to claim 13, wherein the modular, annular surge element is fixed by at least one fixing element positioned on an inner side of the second molded housing part.
