Abstract

A filling device for a pressure vessel of a motor vehicle includes a filling neck via which an operating medium can be filled into a pressure vessel, a dust cap which can be plugged onto the filling neck and which, together with the filling neck, delimits a filling volume. A housing apparatus includes a main element and a cover element which can be adjusted relative to the main element between an open position and a closed position which, together with the main element, delimits a housing interior. The dust cap is arranged in the housing interior. At least one ventilation channel, which is delimited in regions by the dust cap, extends from the filling volume into an environment separated from the housing interior by way of the cover in its closed position and has at least one direction-reversing element.
