The invention relates to a valve for an airbag system for a motor vehicle comprising: a housing (20), which extends along a longitudinal axis (21) and surrounds a cavity (22) having a taper (17) and surrounds a control chamber (5); an electrically switchable pilot valve (15), which selectively closes or opens a pilot opening (6) of the control chamber (5); a piston (3), which is arranged in the cavity (22) and can be moved along the longitudinal axis (21) relative to the housing (20); an equalization line (4, 18), which connects an inlet (1) of the valve (100) to the control chamber (5) for fluid communication, wherein: a sealing seat (2) is formed at the taper (17) in order to block a gas flow from the inlet (1) to an outlet (14) of the valve in a closed position, in which the piston (3)is in contact with the sealing seat (2), and to allow said gas flow in further positions; the control chamber (5) is arranged on a first side (24) of the piston (3) facing away from the sealing seat (2); and the piston (3) has a first diameter (25) on a side (23) facing the sealing seat (2) and a second diameter (26) on the first side (24), the first diameter (25) being less than the second diameter (26).

    本发明涉及用于机动车辆安全气囊系统的阀,它具有:‑壳体(20),该壳体沿纵向轴线(21)延伸并围绕具有渐缩部分(17)的空腔(22)以及围绕控制室(5),‑可电气切换的先导阀(15),该先导阀选择性地封闭或开通控制室(5)的先导孔(6),‑活塞(3),该活塞设置在空腔(22)中并且能沿纵向轴线(21)相对于壳体(20)移动,‑平衡管路(4、18),该平衡管路将阀(100)的输入端(1)与控制室(5)相连接以实现流体连通,其中,‑在渐缩部分(17)上设置有密封座(2),该密封座在活塞(3)与密封座(2)相接触的封闭位置阻止从阀(100)的输入端(1)流向输出端(14)的气流,而在其他位置开通该气流,‑控制室(5)设置在活塞(3)的背离密封座(2)的第一侧(24),并且‑活塞(3)在面向密封座(2)的一侧(23)具有第一直径(25),在第一侧(24)具有第二直径(26),其中,第一直径(25)小于第二直径(26)。
