Problems solved by technology

[0005] However, if the vent has a fluid-carrying connection between the vent line and the filler pipe, there is the problem that fuel can flow from the fuel pump if the fuel pump nozzle allows continuous flow, ie if there is a fault that causes the fuel pump nozzle to not close. The nozzle passes via the filler pipe and the fluid delivery connection to the ventilation line and thus to e.g. the fuel vapor filter

Embodiment Construction

[0039] figure 1 A ventilation device according to the invention is shown having a valve device 3 mounted on a filling pipe 6 of a tank device.

[0040] The filling pipe 6 extends from the upper end, which is designed as a tank stub, as far as a tank connection 17, where the filling tube 6 can be connected or connected to a tank (not shown) of the tank arrangement.

[0041] The vent outlet line 2 can likewise be connected via the tank connection 17 to the tank of the tank arrangement, and the vent inlet line 1 can also be indirectly connected to the tank of the tank arrangement. In this case, the ventilation inlet line 1 forms a line branching off from a refueling ventilation line 18 with a tank connection 17 via a compensating tank 19 . The larger, ie unbranched, portion of the refueling vent line 18 forms a fuel vapor filter line 20 and may be connected to a charcoal filter or via charcoal filter connection 21 to some other fuel delivery filter.

[0042] The arrows shown in...

Abstract

A valve device for a ventilation device of a tank installation of a motor vehicle, wherein the valve device (3) comprises an inlet (4) connectable to a ventilation inlet line (1) of the ventilation device and a ventilation outlet connectable to the ventilation device a tank outlet (5) of the pipeline (2), and a filling pipe outlet (7) capable of being connected to a filling pipe (6) of the tank device, wherein the valve device (3) also includes a tank valve seat (8 ) and a filling pipe valve with a filling pipe valve seat (9), wherein the inlet (4) and the tank outlet (5) can be opened and closed by the tank valve, and the inlet (4) is connected to the filling pipe valve. The connection between the pipe outlet (7) can be opened and closed by means of the filling pipe valve, the ventilation device including such a valve device and the tank device including this through this.

Description

technical field [0001] The invention relates to a valve arrangement for a ventilation arrangement of a storage tank arrangement of a motor vehicle, a ventilation arrangement comprising the valve arrangement, and a storage tank arrangement comprising the ventilation arrangement. Background technique [0002] Venting devices are used in fuel tanks of motor vehicles in order to remove from the tank the gases generated in the tank during the operation of the tank or during refueling of the tank (exhaust gas), or to remove the required gas ( Especially air) is supplied to the storage tank (intake air). For this purpose, a vent line leads out of the storage tank and the gas is led to the outside via intermediate stages such as vapor traps and make-up tanks, eg usually via a fuel vapor filter such as an activated carbon filter. In this case, it is conceivable to open the vent line only during refueling operations (refueling vent line), or to exclusively or additionally open the va...
