In order to improve a compensation reservoir for a hydraulic operating system, in particular for a hydraulic brake system or a clutch system, comprising a housing in the interior of which a storage chamber which is provided for storing hydraulic medium is bounded by a separating element which changes its shape in accordance with a volume of the storage chamber, it is proposed that the housing engages over the separating element in all of its shapes, which correspond to possible volumes of the storage chamber, in a protective manner, that a filling level-indicating region of the separating element changes its position in the housing when the volume which is taken up by the hydraulic medium which is stored in the storage chamber changes, and this position in each case represents a filling level-indicating position, and that the filling level-indicating position which is situated within the housing is visible from outside the housing through a viewing region of the housing.

A method and a system are provided for adjusting a pressure of a medium to a target pressure. The method includes: providing a pneumatic structure in which the medium is at a medium pressure that is a starting pressure; providing an adsorptive material operable within a range of temperatures that is proportionate with a range of medium pressures at which the pneumatic structure is operable; and adjusting a temperature of the adsorptive material to effect an adjustment of the medium pressure to the target pressure for performing a selected function. The system performs the method and includes the absorptive material and at least one regulator for adjusting the temperature of the adsorptive material.

A vehicle braking system includes a primary system including at least one pneumatic brake pipe control valve, and a secondary back-up system configured to facilitate vehicle braking without human intervention. The secondary back-up system includes a first air reservoir coupled to supply pressurized air to the at least one pneumatic brake pipe control valve, a second air reservoir, a choke adapted to allow airflow at a specified airflow rate, and a solenoid valve adapted to selectively couple and decouple the first air reservoir and the second air reservoir via the choke, according to an energization state of the solenoid valve.

A hydraulic block, the upper side of which is provided with a brake-fluid reservoir which is fixed in place on the front surface and on the rear surface of the block by fastening apparatus/device (arrangement). The front fastening apparatus/device (arrangement) is formed by a tab that projects from the underside of the reservoir, this tab being screwed to the front surface of the block. The rear fastening apparatus/device (arrangement) is made up of a tab, which projects from the rear side of the reservoir and is formed by a hook that is supported by a carrier that is fastened to the rear side of the hydraulic block and forms a support for the tab, as well as a clamp, which connects the tab to the hook.

A fluid system for a vehicle is provided. The fluid system is configured to couple to a chassis of the vehicle. A frame assembly of the fluid system is configured to couple with the chassis directly or with another component that is coupled, directly or indirectly, with the chassis. A cowling of the fluid system can enclose a fuel pressure vessel and an auxiliary fluid vessel. The auxiliary fluid vessel is configured to be placed in fluid communication with the component powered or operated by the fluid therein.

A brake-actuating device for a vehicle brake system comprises a fluid reservoir and a master cylinder arrangement. The fluid reservoir has an outlet connection, and the master cylinder arrangement has an inlet connection. The outlet connection of the fluid reservoir and the inlet connection of the master cylinder arrangement, in the connected-together state, define at least one axially overlapping connection region through which a fluid channel for the feed of fluid from the fluid reservoir into the master cylinder arrangement extends. Furthermore, the brake-actuating device comprises a sealing element, which is arranged in the connection region and seals off the latter to the outside, and a filter element for filtering the fluid to be fed to the master cylinder arrangement. The sealing element holds the filter element in a predetermined position in the fluid channel.
