使多个液压致动部件同步的系统和装置
摘要：
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。在申请人教导的多种实施方式中，例如但不局限于机动车辆提升架，公开了使提升架的平台同步的系统和方法，以使得它们共面，其中在一些实施方式中是保持大体上水平的构造。所述系统包括液压流体储存器和通过第一流体流动通路与液压流体储存器流体连通的至少两个液压致动部件。而且，根据申请人教导的多种实施方式，设置有排出阀，所述排出阀通过第二流体流动通路与液压流体储存器和液压致动部件选择性流体连通。而且，根据申请人教导的多种实施方式，所述系统还包括响应所述至少两个液压致动部件的相对位移的控制单元。控制单元选择性控制排出阀，使得响应至少两个液压致动部件的相对位移，控制单元使排出阀致动以使至少一部分液压流体可以通过第二流体流动通路离开液压致动部件中的至少一个以及使液压致动部件同步。
摘要（英）：

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.
