The invention relates to an equalizing container (35) for a hydraulic motor-vehicle brake system with a housing comprising a container inner space with at least one pressure-medium chamber (38) and a device for monitoring a container filling level comprising a switching unit which protrudes with a contact carrier into a guide sleeve (2) which extends into a separate chamber (37) of the container inner space, wherein a sensor or switching element which is arranged on the contact carrier can be switched by means of a sensor (3) which is guided on the guide sleeve (2), at a switching point at which the switching unit generates a signal for an electronic control unit, and wherein the separate chamber (37) is connected to the pressure-medium chamber (38) via a pressure-medium connection (34). According to the invention, valve means (36) are provided, by way of which the pressure-medium flow between the separate chamber (37) and the pressure-medium chamber (38) can be controlled.
