Problems solved by technology

Correspondingly, a blockage of the valve device or solenoid valve can occur, so that a ventilation connection can no longer be established subsequently
Accordingly, the tank cannot be ventilated and / or ventilated only insufficiently, so that impermissibly high or low pressures occur in the tank and thus lead to damage to the tank

Embodiment Construction

[0022] figure 1 The tank system 1 of a motor vehicle is schematically shown. The storage tank system has a storage tank 2 and a storage tank ventilation device 3. In particular, a valve device 4 and a filter device 5 are assigned to the tank ventilation device 3. The valve device 4 consists of an on-off valve 6 which has a cross-sectional adjustment element 7 and an actuator 8 connected to the cross-sectional adjustment element, ie, for example, an armature with an associated coil. In the latter case, the on-off valve 6 acts as a magnetic valve. In addition, the valve device 4 has two opposite pressure limiting valves 9 and 10. The pressure limiting valves are parallel to each other and also to the switching valve 6. The filter device 5 is present in the ventilation connection 11, which is shown, for example, by a ventilation connection line, which is connected on one side to the tank 2 and on the other side to the filter device 5 . In addition, an outlet safety device 12 ...

Abstract

The invention relates to a method for operating a tank device (1) of a motor vehicle. The tank device (1) has a tank (2) and a tank ventilating device (3) with at least one control valve (6) to which an excitation current can be applied, and the control valve (6) opens only when the excitation current exceeds an excitation current threshold over a specified period of time. An excitation current which is greater than the excitation current threshold is also at least temporarily applied to the control valve (6) for heating purposes in a first operating mode when ventilation of the tank (2) is not specified by a controller of the tank device (1). The invention further relates to a tank device (1) of a motor vehicle.

Description

Technical field [0001] The present invention relates to a method for operating a storage tank system of a motor vehicle, wherein the storage tank system has a storage tank and a storage tank ventilation device, and the storage tank ventilation device has at least one switch valve that can be applied by an excitation current only when When the excitation current exceeds the excitation current threshold for a certain period of time, the on-off valve opens. In addition, the present invention also relates to a tank system of a motor vehicle. Background technique [0002] Methods of the aforementioned type are known from the prior art. For example, the tank of the tank system may be a fuel tank or an auxiliary material tank, where the auxiliary material is especially a reducing agent. Usually there is always a fluid in the tank, that is, for example, fuel or auxiliary materials, which are in liquid form and possibly also in gaseous form. The gaseous fluid is mixed with the air loca...
