PRESSURE COMPENSATED ACTIVE SUSPENSION ACTUATOR SYSTEM

Active suspension actuator systems including an actuator with a compression volume and an extension volume are described. In some embodiments, the system includes one or more flow control devices in fluid communication with the compression volume and/or the extension volume of the actuator. In some instances, a flow control device may include a pressure balanced blow-off valve (PBOV). In some embodiments, the system includes a high capacity bidirectional base valve. In some embodiments, two or more flow control devices cooperate to, for example, damp low amplitude oscillations in the extension and/or compression volumes, and to allow the build-up of pump generated differential pressures while discharging rapid road induced differential pressure spikes between the extension and compression volumes. 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
