Abstract:
1. A snubber, comprising: a body containing fluid; a piston, including a piston rod, adapted to slide within the fluid in the body; a lockup valve positioned outside of the piston rod wherein under operating conditions the lockup valve is unlocked enabling the piston to move freely, and wherein under a predetermined set of conditions the lockup valve is locked limiting the motion of the piston; a main reservoir defined by the body and containing fluid, and a second reservoir defined within the piston rod containing a reserve of fluid, wherein the lockup valve divides at least a portion of the body into a first chamber and a second chamber, wherein under the predetermined set of conditions the lockup valve prevents fluid flow between the two chambers, and wherein under the predetermined set of conditions, the lockup valve is lockable outside of the piston rod and enabled to remain locked when there is a difference in fluid pressure between the two chambers.
