LIFTGATE HYDRAULIC CLOSURE CYLINDER

摘要

A liftgate system may include a closer cylinder assembly for use in opening and closing a deck. The closer cylinder assembly may have a hydraulic fluid portion on one side of a piston and an air (or other gas) portion on the other side of the piston. The deck is closed using hydraulic pressure in the hydraulic fluid portion to move the piston in one direction. The deck is assisted in opening using gas pressure in the gas portion to move the piston in another direction.
