Abstract: The present invention discloses a method and operating liquid container system for controlling the internal pressure of an operating liquid container of a motor vehicle, wherein the method includes determining an internal pressure of the operating liquid container by means of a pressure sensor arranged in an operating liquid container interior; comparing the determined internal pressure with a predetermined maximum internal pressure by means of an electronic control device; outputting an opening signal from the control device to a vent valve that is arranged in a vent line or between the operating liquid container interior and the vent line, wherein the vent line fluidically connects the operating liquid container interior to the atmosphere when the determined internal pressure is equal to the maximum internal pressure or above the maximum internal pressure; and transferring the vent valve into an open position.

Abstract: An improved venting and/or air admission valve for an operating fluid reservoir, wherein different shutoff levels (SOH) can be achieved. The venting and/or air admission valve is distinguished by the fact that it comprises an adapter, which can be fastened on an operating fluid reservoir wall, and that a valve housing of the venting and/or air admission valve can be fastened on the adapter in such a way that the adapter is arranged between the operating fluid reservoir wall and the valve housing.

Abstract: A method for controlling a filling process of an operating fluid container, which can be filled by a filling device via a filling tube opening into the operating liquid container, wherein the operating fluid container is provided with a venting valve, which can be electrically operated between an open position, in which the operating liquid container is fluidically connected to the atmosphere, at least indirectly, by the venting valve, and a closed position, in which the operating fluid container is fluidically separated from the atmosphere by the venting valve.
