A brake system with a wheel brake has a fluid reservoir and a valve assembly in fluid communication with the reservoir via a first conduit. The valve assembly is in fluid communication with the wheel brake via a second conduit. The valve assembly includes a bypass valve which only permits fluid flow from the first conduit to the second conduit when the fluid pressure within the first conduit is above a predetermined pressure level above atmospheric pressure. The valve assembly further includes a check valve in a parallel path arrangement relative to the bypass valve such that the check valve permits fluid flow from the second conduit to the first conduit, and prevents fluid flow from the first conduit to the second conduit. The brake system further includes a first source of pressurized fluid providing fluid pressure for actuating the wheel brake, wherein the first source of pressurized fluid is selectively in fluid communication with the second conduit.

A fluid container having at least one internal chamber for receiving a fluid, and having at least one connector for hydraulically connecting the internal chamber to a downstream hydraulic apparatus, wherein the connector at the end thereof toward the internal chamber has a mouth portion. In order to propose an improved fluid container by way of which high volumetric flows can also pass through the connector at high throughflow rates with low losses and reduced resistance, it is proposed that an escape value of the connector is provided so as to be larger than 0.82, and the mouth portion in relation to a container wall region that directly surrounds the mouth portion is at least in portions designed so as to be raised in the direction of the internal chamber.

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.
