Abstract
A system and method is provided for an adjustable spring plunger bumper with high initial load and low final load. The spring plunger bumper includes an exterior body surrounding a plunger. The plunger has a plunger indent into which a displacement ball is induced by a ramp sleeve biased by a ramp sleeve spring. As the plunger is displaced relative to the exterior body, the displacement ball contacts a lower displacement ball inclined surface, which provides a high initial load resisting the displacement of the plunger. However, as the displacement of the plunger continues, the displacement ball comes into contact with a smooth lower displacement ball indent surface which provides a lower load. A return spring is positioned between the plunger and the exterior body to return them to their initial position relative to each other when the displacement of the plunger is removed.
