Abstract: A brake unit having a container which serves for accommodating working fluid and which is arranged with at least one connector piece in a receiving bore and which is sealed off by a sealing element which extends radially around the connector piece. In order to offer a simple, inexpensive and pressure-tight interface between connector piece in a receiving bore, it is proposed that a form fit transversely with respect to the direction of the longitudinal axis of the connector piece is formed by a displacement of the material of the sealing element during the installation of the connector piece in the receiving bore.

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.

Abstract: The invention relates to an assembly including a pressure medium reservoir and a manually actuable master cylinder, in particular for a hydraulic motorcycle brake system, wherein the pressure medium reservoir is connected permanently to the master cylinder by at least one pressure medium connection, wherein the master cylinder has at least one pressure chamber, which can be connected to wheel brakes. According to the invention, provision is made for a protection device to be arranged in the region of the pressure medium connection, the device preventing air from penetrating into the pressure chamber and allowing air to escape in the direction of the pressure medium reservoir.

Abstract: The invention relates to a reservoir, in particular for hydraulic motor vehicle brake systems, having one or more pressure medium chambers, a filler neck for filling the reservoir with pressure medium and a pressure medium passage, which is connected to the filler neck and has an opening facing the pressure medium chamber. In order to provide a reservoir which reliably prevents the pressure medium from leaking when the vehicle is in extreme positions and which, at the same time, can be produced in a simple and inexpensive manner, the proposal according to the invention is that the pressure medium passage be provided as a lateral channel which extends in the longitudinal direction along the reservoir, starting from the filler neck, and be formed by walls of an upper part and of a lower part of the reservoir.

Abstract: A compensation tank for hydraulic motor vehicle brake systems, including a tank housing having at least one pressure medium chamber which can be filled with pressure medium via a filler neck, and a cap which can be fastened to the filler neck by a threaded connection having a cap thread and a tank thread. The cap and the tank housing each have a respective stop, which stops permit a predetermined positioning of the cap in relation to the tank housing.

Abstract: A pressure medium container for hydraulic motor vehicle braking systems, with at least one chamber which can be filled with a liquid medium via a filler neck, and with a cover which can be fastened to the filler neck and has means for equalizing the pressure between the chamber and the atmosphere, wherein a sealing element is provided to prevent the liquid medium from emerging from the chamber. The sealing element has a space exposed to the atmosphere and has one or more openings facing the chamber, the space being configured such that liquid medium penetrating the space undergoes an increase in surface area, while its volume remains constant, when displaced by means of a further gaseous medium, and, when a threshold surface tension is reached, the liquid medium is forced back into the chamber such that the gaseous medium can flow into the atmosphere via the sealing element.

Abstract: A method for optimizing the switching behaviour of a tank warning device of a compensation tank, in particular for a hydraulic motor-vehicle brake system, with a housing and the tank warning device for monitoring the tank filling level of the compensation tank. The tank warning device including a switching unit with a reed contact as a switching element, which can be switched by means of a magnet at a switching point S at which the switching unit generates a signal for an electronic control unit. A compensation tank including a tank warning device which has been optimized in terms of switching by means of a method according to the invention is also disclosed. The reed contact and the magnet are matched to one another in a manner optimized in terms of switching in such a way that the magnet switches at a single switching lobe of the reed contact.
