Abstract

A filling head, which includes:A filling head housing for conveying operating fluid in a supply sense from a supply-intake region, which is configured for introducing operating fluid into the filling head, to an outlet port,A venting structure which allows the conveying of gas in a venting sense which is opposite to the supply sense,Where the supply-intake region exhibits a hollow plug-in connector extending along a virtual nozzle path with a plug-in orifice through which an intake space connected fluid-mechanically with the outlet port is accessible,Where an inner nozzle wall bordering the intake space exhibits functional formations projecting into the intake space as part of the venting structure,Where on the external side of the plug-in connectors there is provided an active formation which is configured to interact with an internal thread of a supply device for the latter's positional stabilization at the plug-in connector.The filling head provides that the active formation reaches along the nozzle path up to a main body of the filling head housing, from which the plug-in connector projects.

First claim

The invention claimed is:

1. A filling head for introducing operating fluid into an operating fluid tank of a motorized vehicle and for venting the operating fluid tank during the introduction of operating fluid into it, where the filling head comprises:
A filling head housing for conveying operating fluid in a supply sense from a supply-intake region, which is configured for temporally provisional intake of a supply device, such as for instance a spigot or reservoir container neck, for introducing operating fluid into the filling head, to an outlet port of the filling head housing, where the outlet port is arranged in the supply sense downstream of the supply-intake region,
A venting structure, which during the conveying of operating fluid through the filling head housing in the supply sense allows the conveying of gas in a venting sense which is opposite to the supply sense,
Where the supply-intake region of the filling head exhibits a hollow plug-in connector extending along a virtual nozzle path with a plug-in orifice through which an intake space is accessible for temporally provisional intake of the supply device, where the intake space is connected fluid-mechanically with the outlet port,
where an inner nozzle wall bordering the intake space radially relative to the nozzle path exhibits in a circumferential direction about the nozzle path functional formations arranged at a distance from one another and projecting into the intake space, such that the functional formations form between them in a circumferential direction venting volumes as part of the venting structure,
where on an external side of the hollow plug-in connector there is provided an active formation which is configured so as to interact with an internal thread of the supply device for the latter's positional stabilization at the hollow plug-in connector,
wherein the active formation reaches along the nozzle path up to a main body of the filling head housing, from which the hollow plug-in connector protrudes;
wherein the active formation further comprises an external thread,
wherein the external thread is discontinuous in at least one angular sector around the nozzle path, such that the at least one angular sector is free from an external thread formation.

2. The filling head according to claim 1 , wherein the active formation further comprises at least one longitudinal rib extending along the nozzle path and jutting out radially from the hollow plug-in connector.

3. The filling head according to claim 1 , wherein the active formation exhibits at least one outer wall section, including an outer wall section surrounding the nozzle path completely, of the hollow plug-in connector.

4. The filling head according to claim 3 , wherein the active formation exhibits an outer surface facing away radially from the nozzle path, which is configured as a sliding surface for a sliding abutting contact with a boundary surface of the internal thread.

5. The filling head according to claim 1 , wherein the active formation exhibits an outer surface facing away radially from the nozzle path, which is configured as a sliding surface for a sliding abutting contact with a boundary surface of the internal thread.

6. The filling head according to claim 1 , wherein on the external side of the hollow plug-in connector there is arranged a sealing formation along the nozzle path at a distance from the plug-in orifice.

7. The filling head according to claim 6 , wherein the sealing formation is arranged along the nozzle path between the plug-in orifice and the active formation.

8. The filling head according to claim 1 , wherein along the nozzle path following the hollow plug-in connector in the supply sense, there is arranged in the main body of the filling head housing a magnet arrangement whose magnetic field acts on an operating fluid supply route configured in the filling head.

9. The filling head according to claim 1 , wherein the filling head housing is fitted together from several housing components, where the hollow plug-in connector with an end section of the main body of the filling head housing is configured integrally.

10. The filling head according to claim 1 , wherein the filling head as part of the venting structure exhibits a venting line, which at least section-wise is configured as spatially separate from a main volume of the filling head housing through which operating fluid flows in the supply sense during the supply operation.

11. The filling head according to claim 10 , wherein the venting line discharges into the main volume of the filling head housing.

12. The filling head according to claim 11 , wherein the filling head housing exhibits at least one integral housing component, which forms part of the main body of the filling head housing and in which both at least one part of the main volume of the filling head housing and at least one part of the venting line are configured.

13. The filling head according to claim 10 , wherein the filling head housing exhibits at least one integral housing component, which forms part of the main body of the filling head housing and in which both at least one part of the main volume of the filling head housing and at least one part of the venting line are configured.

14. The filling head according to claim 13 , wherein the filling head housing exhibits more than one integral housing component, of which every housing component forms part of the main body of the filling head housing and in every one of which at least one part of the main volume of the filling head housing and also at least one part of the venting line are configured.

15. The filling head according to claim 2 , wherein the at least one longitudinal rib extending along the nozzle path is a plurality of such longitudinal ribs arranged at a distance from one another in a circumferential direction around the nozzle path.

16. A filling head for introducing operating fluid into an operating fluid tank of a motorized vehicle and for venting the operating fluid tank during the introduction of operating fluid into it, where the filling head comprises:
A filling head housing for conveying operating fluid in a supply sense from a supply-intake region, which is configured for temporally provisional intake of a supply device, such as for instance a spigot or reservoir container neck, for introducing operating fluid into the filling head, to an outlet port of the filling head housing, where the outlet port is arranged in the supply sense downstream of the supply-intake region,
A venting structure, which during the conveying of operating fluid through the filling head housing in the supply sense allows the conveying of gas in a venting sense which is opposite to the supply sense,
Where the supply-intake region of the filling head exhibits a hollow plug-in connector extending along a virtual nozzle path with a plug-in orifice through which an intake space is accessible for temporally provisional intake of the supply device, where the intake space is connected fluid-mechanically with the outlet port,
where an inner nozzle wall bordering the intake space radially relative to the nozzle path exhibits in a circumferential direction about the nozzle path functional formations arranged at a distance from one another and projecting into the intake space, such that the functional formations form between them in a circumferential direction venting volumes as part of the venting structure,
where on an external side of the hollow plug-in connector there is provided an active formation which is configured so as to interact with an internal thread of the supply device
