This reservoir tank is provided with a reservoir body formed in the shape of a hollow box inside which a hydraulic fluid is stored, and is connected to a vehicle master cylinder in such a way that brake fluid flows into and out of the same. The reservoir body is provided with a top plate portion formed in the shape of a plate. A flow path portion having one or a plurality of flow paths formed in a serpentine fashion and opening downward in a vertical direction is provided in a protruding manner on an inner wall surface of the top plate portion, and a slit is provided on a downstream side of the flow path.

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 brake device includes a first flow path unit guiding a braking hydraulic pressure by connecting some of wheel cylinder units and a master cylinder unit; a second flow path unit guiding a braking hydraulic pressure by connecting the others of the wheel cylinder units and the master cylinder unit; a third flow path unit connecting a reservoir and pump units, and connected with the first flow path unit; a fourth flow path unit connecting the reservoir and the pump units, and connected with the second flow path unit; a fifth flow path unit connecting the reservoir and the first flow path unit; a sixth flow path unit connecting the reservoir and the second flow path unit; a seventh flow path unit selectively connecting the first and second flow path units; and an eighth flow path unit connecting the second flow path unit and the reservoir.

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 leak control device includes a reservoir fluidly coupled with a brake pipe of a vehicle brake system. The leak control device also includes a conduit fluidly coupled with the reservoir and having an orifice that directs fluid out of the reservoir at a leak rate. The leak control device includes a valve fluidly coupled with and disposed between the reservoir and the conduit. The valve may open and direct the fluid out of the reservoir and out of the vehicle brake system at the leak rate responsive to a pressure of the fluid in the brake pipe being no less than a pressure of the fluid in the reservoir.

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.
