Abstract
A gas spring assembly includes an end member, a piston assembly and a flexible sleeve secured therebetween. An end closure secures an end of the flexible sleeve to the piston assembly. A connector fitting connects the end closure to a support post of the piston assembly. The connector fitting includes a fitting passage and a first annular groove. A jounce bumper assembly is supported on the connector fitting. The jounce bumper assembly includes a bumper body and a bumper mount. The bumper mount includes securement pin having a second annular groove. A retaining member is received within the first and second annular grooves such that the jounce bumper assembly can freely rotate relative to the connector fitting while substantially restricting axial displacement of the jounce bumper assembly relative to the piston assembly during such rotation.
