Abstract

A pressure medium container for a hydraulic motor vehicle brake system. A pressure medium container is provided including a container casing the interior of which can be filled with a pressure medium via a filler pipe and is closed off by a closure cap fixed to the filler pipe. A sealing element made from an elastomeric material is provided between the filler pipe and a bottom of the closure cap. The sealing element has a valve which rests on a support pedestal arranged on the closure cap is closed in a non-actuated initial state and reaches an opened actuated state under the control of differential pressure, whereby a pressure is equalized between an interior of the pressure medium container and an ambient atmosphere. Direction-dependently, the valve has different valve opening resistances.
