    • A dynamic control valve system adapted for inflatable restraint systems for vehicles includes a control valve having an inlet in fluid communication with a source of pressurized fluid, and an outlet in fluid communication with an inlet of the air bag. The control valve includes a valve member actuatable between a flow preventing position and a position spaced away from the flow preventing position. The control valve supplies the high pressure fluid through the control valve to the inflatable restraint for inflating the inflatable restraint when the valve member is moved away from its flow preventing position. The control valve includes a valve spool which cooperates with a valve casing to define a plurality of flow paths. Consequently, the actuation of the valve member between closed and open positions is substantially independent of forces produced by flow of the high pressure fluid through the valve. In one embodiment, the valve member, when unactuated, is maintained in its first position without mechanical bias. In another embodiment, the control valve includes a bias structure for biasing the valve member toward its closed position. In one embodiment, the valve member is moved between the first and second positions based upon at least one vehicle parameter or occupant parameter. Such parameters may be selected from, for example, vehicle deceleration, vehicle acceleration, and/or the presence, weight and/or position of an occupant of the vehicle.
    • 适用于车辆的可充气约束系统的动态控制阀系统包括具有与加压流体源流体连通的入口的控制阀以及与气囊的入口流体连通的出口。 控制阀包括可在防流动位置和与防止流动位置间隔开的位置之间致动的阀构件。 控制阀将高压流体通过控制阀提供给充气式约束装置,以在阀构件远离其防止流动位置时使充气式约束件膨胀。 控制阀包括与阀壳配合以限定多个流路的阀芯。 因此,阀构件在闭合位置和打开位置之间的致动基本上与通过阀的高压流体的流动产生的力无关。 在一个实施例中,阀构件未被致动时保持在其第一位置而没有机械偏置。 在另一个实施例中,控制阀包括用于将阀构件偏压到其关闭位置的偏置结构。 在一个实施例中,阀构件基于至少一个车辆参数或乘员参数在第一和第二位置之间移动。 这样的参数可以选自例如车辆减速,车辆加速度和/或车辆的乘员的存在,重量和/或位置。
