A motion stabilizer for yieldingly urging a relatively movable load member toward a normal or centered position relative to another load member includes a telescoping body that shortens (retracts) as the load members move toward one another and lengthens (extends) as the load members move apart. A reaction unit is mounted within an axially extending internal chamber defined within the body. The reaction unit has a normal length and a displaced length. The reaction unit may include a spring such as a gas spring or coil spring, and the spring may operate in compression or in expansion. The reaction unit may provide damping. Depending of the characteristics of the reaction unit, the displaced length may be either longer or shorter than the normal length. The telescoping members of the body are constructed and arranged to displace the reaction unit away from the normal length and in the same direction toward the displaced length in response to both lengthening and shortening of the body, providing a stroke doubling effect. |
