An active suspension actuator system is described that includes an actuator having a compressed volume and an expanded volume. In some embodiments, the system includes one or more flow control devices in fluid communication with a compressed volume and/or an expanded volume of the actuator. In some examples, the flow control device may include a pressure balanced drain valve (PBOV). In some embodiments, the system includes a high capacity bi-directional base valve. In some embodiments, two or more flow control devices cooperate to dampen low amplitude oscillations, e.g., in an extended volume and/or a compression volume, and to allow pump-generated pressure differences to increase while spiking the road-induced rapid pressure difference between the compression volume and the extended volume.

    描述了包括致动器的主动悬架致动器系统,该致动器具有压缩容积和扩展容积。在一些实施方式中,该系统包括与致动器的压缩容积和/或扩展容积流体连通的一个或更多个流动控制装置。在一些实例中,流动控制装置可以包括压力平衡排放阀(PBOV)。在一些实施方式中,系统包括高容量双向基部阀。在一些实施方式中,两个或更多个流动控制装置进行合作以对例如扩展容积和/或压缩容积中的低幅度振荡进行阻尼,并且允许泵产生的压力差增加,同时将道路引起的压缩容积与扩展容积之间的快速压力差尖峰排放。
