Abstract:
1. A gas spring assembly comprising: a flexible wall having a longitudinal axis, said flexible wall extending peripherally about said longitudinal axis between opposing first and second ends and at least partially defining a spring chamber; a first end member operatively connected in a substantially fluid-tight manner across said first end of said flexible wall; and, a second end member spaced longitudinally from said first end member and operatively connected in a substantially fluid-tight manner across said second end of said flexible wall, said second end member including an outer side wall having an outer surface with a first plurality of corrugations, an inner side wall having an inner surface and an opposing outer surface with a second plurality of corrugations, said first plurality of corrugations disposed peripherally about said longitudinal axis and extending longitudinally along said outer side wall such that said first plurality of corrugations are exposed along said outer surface of said outer side wall, and said second plurality of corrugations disposed peripherally about said longitudinal axis and extending longitudinally along said inner side wall such that said second plurality of corrugations are exposed along at least one of said inner and outer surfaces of said inner side wall; said second end member having a cross-sectional profile in a reference plane oriented transverse to said longitudinal axis in which at least said first plurality of corrugations include a curved wall portion having wall portion curvature and an outermost tangential extent, said second end member having an end member curvature defined by a plurality of said outermost tangential extents and approximating an outermost periphery of said second end member in said reference plane, said end member curvature being different than said wall portion curvature of said curved wall portions.
