A filling level sensing device for a liquid reservoir, in particular for a compensation tank of a vehicle brake system, includes at least one float, at least one sensor element connected to the at least one float, and at least two sensors for detecting the position of the at least one sensor element. The float may be designed to come into contact with the liquid in the liquid reservoir. At least one of the two sensors may sense a change in the filling level of the liquid reservoir depending on the position of the at least one sensor element relative to the at least two sensors.

A vehicle fluid reservoir system has a fluid tank that contains a vehicle fluid and a light source in an interior of the fluid tank that illuminates the interior of the tank and the surface of fluid in the tank. The illumination of the surface of fluid in the tank is visible from outside the tank, enabling a quick and easy determination of the level of fluid inside the tank. A switch is operatively communicated with the light source. The switch is operable to control the light source to emit light and illuminate the interior of the tank and the fluid surface in the interior of the tank, and to control the light source not to emit light.

A fluid container for supplying a consuming device with a working fluid, including at least one connector piece having a shut-off valve arranged therein for preventing undesired escaping of the working fluid from the fluid container. In order to increase safety against undesired emptying of the fluid container, it is provided that the valve closure body, in the closed state of the shut-off valve, is accommodated in the fluid container completely inside a contour formed by an outer edge of the connector piece, and provision is made, for support against the valve closure body, of a support, which, upon insertion of the connector piece into the receiving seat, engages at least regionally into the connecting duct and in this way displaces the valve closure body in the connecting duct.

A fluid container for a hydraulic unit comprises a container housing which has at least one connection part, which can be shut off by means of a shut-off device arranged in the fluid container. The container housing has at least one internal chamber and a channel for connecting the internal chamber to the hydraulic unit. The connection part and the shut-off device are combined in a separate module, which is connected to the container housing.

A hydraulic disc braking system is disclosed. The system has a manually operated control device for a cyclist to issue a braking command. The system has a master cylinder assembly having a membrane dividing the hydraulic fluid tank into a variable volume filled chamber and a complementarily variable volume empty chamber. A membrane detector senses the presence of the membrane relative to a predetermined position in the tank and/or a meter measures the distance of the membrane from the ceiling of tank.

The present disclosure pertains to a coupling device for coupling a fluid reservoir for a brake fluid with a brake actuation device. The coupling device includes at least one coupling extension provided at the fluid reservoir with a first recess, a second recess configured in the area of an edge of the brake actuation device as well as a hole configured in the brake actuation device and open to the second recess, a bridge element crossing the second recess along the edge of the brake actuation device and a coupling element with at least one striker, wherein, when the fluid reservoir is coupled to the brake actuation device, the hole is aligned with the first recess along a central longitudinal axis of the striker and the striker passes through the first recess and engages with the hole. The present disclosure also pertains to a vehicle brake system equipped with such a coupling device.
