<p>A multiple stop gas spring that has a second or stop piston assembly (66) in addition to a metering piston assembly (64), connected and movable with the gas spring shaft. The stop piston assembly (66) is preferably spaced axially from the metering piston assembly (64). The stop piston assembly may be utilized to stop movement of the shaft in one direction at preselected position(s) along the shaft's normal stroke, and also, or alternatively, to cause the shaft movement in the one direction to slow incrementally to a cushioned stop when the shaft approached the end of its stroke. The shaft may move in the other direction without any impediment to its movement or may stop in both directions.</p> |
