Abstract

A closure cap for an operating medium tank is provided with a closure device projecting into a fill socket of the operating medium tank. The closure device has a first cap element, a second cap element, and a sealing ring arranged between the first and second cap elements. A lifting assembly axially moves by an axial travel the first and second cap elements relative to each other for opening and closing the fill socket. The lifting assembly has a pressure member acting axially on one of the first and second cap elements. A grip member is provided that is rotatable about a hub and actuates the lifting assembly. A cover disk covering at least partially the fill socket relative to an exterior is connected fixedly to the pressure member of the lifting assembly. The cover disk rotates, together with the pressure member, about the hub.
