Definitions

• the invention relates to a fuel tank for a motor vehicle with a refueling vent and a operational venting having venting device with a venting line of the refueling vent and with one to in designated areas of the fuel tank ge ⁇ led vent line of the operational venting, wherein the refueling vent and the operating ventilation via a line with a Activated carbon filter are connected.
• Such fuel tanks are commonly used in today's motor vehicles and are known in practice.
• Be ⁇ operating venting allows escape of fuel vapors during operation of the motor vehicle and a subsequent flow of air at a consumption of the fuel.
• the refueling vent ⁇ derives from the charged fuel displaced air from the fuel tank through the charcoal filter.
• the charcoal filter communicates with the environment to allow pressure equalization.
• the operating ventilation and refueling are laboriously mounted on the fuel tank.
• the invention is based on the problem of designing a Kraftstoffbe ⁇ container with a venting device so that the fuel tank with the venting device is particularly easy to assemble and manufacture.
• the refueling vent and the operating vent have a common container and that the container each has a chamber for the refueling vent and the strigentlüf ⁇ tion.
• the essential components of the operating ventilation and the refueling vent can be preassembled into a structural unit and used in the fuel tank according to the invention.
• the common, the chambered container can also particularly easy fer ⁇ term.
• the separation of the container in the two chambers allows reliable management of the fuel vapors through the activated carbon filter.
• the chambers are preferably completely separated from each other.
• the construction work for the venting device can be kept particularly low when the refueling vent and the operating vent each have a valve and when the valves are connected to the leading to the activated carbon filter line.
• the valves thereby prevent liquid fuel from reaching the activated carbon filter and damaging it.
• control of the refueling ventilation designed according to another advantageous embodiment of the invention structurally particularly simple if at least one of the valves is designed as a float valve.
• An emptying of the chambers of the ventilation device ges ⁇ taltet particularly simple if the refueling vent and the operational venting each have an ejector on ⁇ and when suction of suction jet pumps are connected to a respective chamber of the refueling vent and the operation ⁇ vent.
• the suction ⁇ jet pumps from a within the fuel tank on ordered fuel pump supplied with fuel as a propellant.
• the chambers of the breather ⁇ processing device during operation of the motor vehicle are always empty. Therefore, designed as a float valves valves to close the lines to the activated carbon filter even in a rollover of the motor vehicle.
• the valves of the venting device therefore also serve as so-called roll-over valves.
• An escape of fuel vapors from the fuel tank can be kept particularly low when the container is disposed within the fuel tank.
• the number of sealing points of the fuel tank is kept particularly low.
• a particularly accurate limitation of feedable the fuel tank amount of fuel is ensured when the vent line of the refueling vent is performed up to a designated cut-off point of the fuel tank and when the tank is below the cut-off is angeord ⁇ net.
• the vent of the fuel tank is closed when the shutdown point. Then no more air can escape from the fuel tank and thus no fuel can be refilled.
• the shut-off point is set thanks to the invention of the free end of the vent line of the refueling vent.
