Abstract:
1. A shock absorber comprising: a pressure tube defining a fluid chamber; a piston assembly slidably disposed within said fluid chamber, said piston assembly dividing said fluid chamber into an upper working chamber and a lower working chamber; a piston rod attached to said piston assembly, said piston rod extending through one of said upper and lower working chambers; a jounce bumper cap disposed at an end of said pressure tube, said piston rod extending through a through bore defined by said jounce bumper cap; a jounce bumper nose retaining feature disposed around said through bore defined by said jounce bumper cap; an elastomeric jounce bumper disposed around said piston rod, said elastomeric jounce bumper having a nose configured to engage said jounce bumper nose retaining feature, said jounce bumper nose retaining feature extending toward said elastomeric jounce bumper to increase a cross-sectional thickness of said jounce bumper cap; wherein engagement between said nose of said elastomeric jounce bumper and said jounce bumper nose retaining feature during a compression movement of said shock absorber restricts radial movement of said nose with respect to said jounce bumper nose retaining feature.
