Provided is a tank neck unit (100, 110) for a vehicle that includes a tank neck (142, 165), a throughflow path (140) and a nonreturn valve(28). The tank neck (142, 165) is designed for a predetermined maximum pressure which is greater than a permissible operating pressure of a pressure accumulator system arranged in the vehicle. The tank neck unit (100, 110) has a shut-off valve (SV, 120), wherein the shut-off valve (SV, 120) is arranged in the throughflow path (140) between the tank neck (142, 165) and an outlet region of the tank neck unit (100, 110), the shut-off valve (SV, 120) being designed to prevent an increase in pressure of the pressure accumulator system arranged in the vehicle beyond the permissible operating pressure. A tank system for a vehicle includes a tank neck unit (100, 110), pressure lines (66) and at least one pressure accumulator vessel (S). |
