A system and method configured to direct the braking energy from a high-pressure port at the motor side of a hydraulic circuit to emergency steering, braking, accumulator(s) charging, and/or various work functions. The system and method are also configured to return hydraulic fluid back to the same high-pressure port when the motor is running as a pump.

A brake assembly includes a reservoir body adapted to store a brake fluid and defining a cylinder bore, and a piston adapted to reciprocate inside the cylinder bore. The brake assembly also includes a base bracket pivotably coupled to a reservoir body and adapted to be mounted to a handlebar, and a handle pivotally coupled to the base bracket and adapted to pivot relative to the base bracket. A drive link is pivotable coupled to the reservoir body and is configured to pivot relative to the reservoir body to advance the piston inside the cylinder bore in response to the pressing of the handle. The handle is configured to be set at a plurality of angular positions with respect to the reservoir body by pivoting the base bracket relative to the reservoir body.

A coupling arrangement between a fluid reservoir and a main brake cylinder for a motor vehicle brake system includes two coupling arms with one coupling aperture each on one of the fluid reservoir or main brake cylinder. The other of the fluid reservoir or main brake cylinder has a mounting portion with a receiving aperture. The coupling apertures and the receiving aperture are aligned with each other along a common axis and accept a coupling bolt. The coupling bolt is configured with a cylindrical shank portion and at least one radially protruding detent projection. At least one of the coupling arms includes a support portion, which has a support surface that radially supports the cylindrical shank portion. Part of the support portion is configured to be elastically deformable with the detent projection to produce a detent connection. The remaining part of the support portion is configured to be substantially deformation-resistant.

A hydraulic fluid container for a hydraulic brake system, includes a hydraulic interface for connecting the hydraulic fluid container to another component. The hydraulic fluid container has a container housing, and the interface includes at least one connector arranged on the container housing, the connector received in a receiving seat of the other component. The connector has a channel which ensures a hydraulic connection between an interior of the container housing and the other component. A blocking device for blocking the hydraulic connection is provided, wherein the blocking device is opened when the connector is received in the receiving seat, the blocking device having a movable valve piston and a sealing element. The aim of the invention is to improve the blocking device and reduce the space requirement and assembly complexity. This is achieved in that the sealing element is designed to secure the position of the valve piston.

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.
