摘要： Applicants' teachings relate to a system and apparatus to synchronize a plurality of hydraulically actuated components. In various embodiments of applicants' teachings, for example, but not limited to, in an automotive vehicle lift rack, a system and apparatus are disclosed to synchronize the platforms of the lift so that they are coplanar, and in some embodiments, maintained in a generally level configuration. The system comprises a hydraulic fluid reservoir, and at least two hydraulically actuated components in fluid communication by a first fluid flow path with the hydraulic fluid reservoir. Moreover, in accordance with various embodiments of applicants' teachings, a discharge valve is provided, the discharge valve in selective fluid communication by a second fluid flow path with a hydraulic fluid reservoir and the hydraulically actuated components. Moreover, in accordance with various embodiments of applicants' teachings, the system further comprises a control unit responsive to relative displacement of the at least two hydraulically actuated components. The control unit to selectively control the discharge valve, so that in response to the relative displacement of the at least two hydraulically actuated components the control unit activates the discharge valve to allow at least a portion of the hydraulic fluid to flow away by the second fluid flow path from at least one of the hydraulically actuated components and to synchronize the hydraulically actuated components.
摘要翻译：申请人的教导涉及使多个液压致动部件同步的系统和装置。在申请人的教导的各种实施例中，例如但不限于在机动车辆升降机架中，公开了一种使升降机的平台同步的系统和装置，使得它们是共面的，并且在一些实施例中，保持在一般水平配置。该系统包括液压流体储存器和通过第一流体流动路径与液压流体储存器流体连通的至少两个液压致动部件。此外，根据申请人的教导的各种实施例，提供排放阀，排出阀通过第二流体流路与液压流体储存器和液压致动部件选择性流体连通。此外，根据申请人的教导的各种实施例，系统还包括响应于至少两个液压致动部件的相对位移的控制单元。所述控制单元选择性地控制所述排放阀，使得响应于所述至少两个液压致动部件的相对位移，所述控制单元启动所述排出阀，以允许至少一部分所述液压流体被所述第二流体从至少一个液压致动部件的流动路径并使液压致动部件同步。
