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 made of a compensating tank and a master cylinder for a hydraulic motor vehicle brake system, wherein the compensating tank has two fastening attachments, each with an opening, wherein openings align with an opening in the master cylinder, and the compensating tank is fastened by a detachable connection by a fastening pin that extends through the aligned openings. In order to improve the installation and possible dismantling of the fastening pin, and at the same time to maintain an optimized assembly weight, the invention proposes that the fastening pin be made of plastic and interact in a positive- or force-locking manner with at least one of the openings of the fastening attachments.

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: An assembly includes a fluid reservoir and a master cylinder for a motor vehicle hydraulic brake system, the fluid reservoir being fastened to the master cylinder by a releasable connection and including at least one connection fitting, which is received in a corresponding connection aperture of the master cylinder. The fluid reservoir includes one or more components, which under a defined force applied to the fluid reservoir, allow a movement of at least one part of the fluid reservoir in the direction of the master cylinder.

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 motor vehicle hydraulic brake system fluid reservoir for use with an electronic control unit. The hydraulic brake system fluid reservoir has a housing including a reservoir interior space having at least one fluid chamber, and a device for monitoring a reservoir filling level including a switch unit, which with a contact carrier projects into a guide sleeve, which extends into a separate chamber of the reservoir interior space. A sensor element or switch element is arranged on the contact carrier and is operable by a pickup carried on the guide sleeve at a switching point, at which the switch unit generates a signal for the electronic control unit. The separate chamber is connected to the fluid chamber by way of a fluid connection. Valve means are also provided, which serves to control the fluid flow between the separate chamber and the fluid chamber.

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.
