The invention relates to a valve assembly (1) for a gas tank (2), comprising a housing (3) in which a gas path (4) is formed, which branches in the housing (3) into an extraction path (5) with an integrated shut-off valve (6) and a filling path (7) with an integrated check valve (8), the check valve (8) comprising an axially movable valve element (11) and a closing spring (9), the spring force of the closing spring acts on the valve element (11) in the direction of the valve seat (10). According to the invention, at least one permanent magnet (17), the magnetic force of which acts in the opening direction, is integrated in the region of the non-return valve (8), preferably in the housing (3) and/or in the valve element (11). The invention also relates to a gas tank (2) having such a valve assembly (1) and to a gas tank system having such a gas tank (2).

    本发明涉及一种用于燃气罐(2)的阀组件(1),包括壳体(3),在所述壳体中构造有燃气路径(4),所述燃气路径在所述壳体(3)内分支成具有集成的截止阀(6)的抽取路径(5)和具有集成的止回阀(8)的充注路径(7),其中,所述止回阀(8)包括可轴向运动的阀元件(11)以及关闭弹簧(9),所述关闭弹簧的弹簧力朝向阀座(10)的方向作用在所述阀元件(11)上。根据本发明,至少一个永磁体(17)集成在所述止回阀(8)的区域中,优选集成在所述壳体(3)中和/或所述阀元件(11)中,所述至少一个永磁体的磁力沿打开方向作用。本发明还涉及一种具有所述阀组件(1)的燃气罐(2)以及一种具有所述燃气罐(2)的燃气罐系统。
