| 摘要 |
The invention relates to a hydraulic device comprising a tubular housing containing a rod to which a plunger is rigidly secured that separates an upper chamber and a lower chamber both filled with a hydraulic fluid, such that, as the plunger and the rod move, they move together in a relative manner axially inside the tubular housing, moving the hydraulic fluid from one chamber to the other and varying the volumes thereof. The invention also comprises a spring that operates under compression resisting the movement of the plunger in one direction when it moves toward a maximum extension position of the hydraulic device. The device also comprises an open elastic ring, the ends of which define an adjustable intermediate passage for the hydraulic fluid in order to adjust damping at the end of the maximum extension of the hydraulic device and in other relative positions. |
