ABSTRACT:
A liquid spring unit operable in both tension and compression includes a liquid spring having a cylinder, a piston, a seal between the cylinder and piston, and compressible liquid in the cylinder. A cylinder extension has diametrically opposed slots therein. A sleeve slidably mounts the cylinder and has diametrically opposed slots in alignment with the slots in the cylinder extension. A link is attached to the piston and has pintles received in the pairs of aligned slots. A first load-receiving member is attached to the sleeve and a second load-receiving member bears on the link to force the piston into the cylinder when the load-receiving members are moved toward each other and causes the cylinder to be moved onto the piston when the load-receiving members are pulled away from each other. A mechanical spring structure having a lower spring force than the liquid spring is interposed between the first and second load-receiving members for attenuating low amplitude forces.
