SYSTEM AND APPARATUS TO SYNCHRONIZE A PLURALITY OF HYDRAULICALLY ACTUATED COMPONENTS

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.
