1. A gas spring assembly comprising;
a first end member; a piston assembly disposed in longitudinally-spaced relation to said first end member, said piston assembly including:
a piston base;a piston body supported on said piston base and including a longitudinally-extending axis, a first end, a second end spaced longitudinally from said first end, a side wall extending between said first and second ends and an end wall extending transverse to said side wall along said first end, said end wall including a first opening formed therethrough, and said side wall at least partially defining a second opening along said second end of said body that is adapted to receive at least a portion of said base; and,a support post extending longitudinally between opposing first and second ends of said piston body, said support post including a first end received within said first opening of said end wall of said piston body and a second end operatively connected to said piston base; a flexible wall extending between opposing first and second ends, said first end of said flexible wall operatively connected to said first end member such that a substantially fluid-tight seal is formed therebetween, said second end of said flexible wall disposed along said piston assembly such that a rolling-lobe is formed along said side wall of said piston body and a spring chamber is at least partially defined between said first end member and said piston assembly; an end closure received along said second end of said flexible wall and secured to said piston assembly such that at least a portion of said flexible wall is captured between said end closure and said end wall of said piston assembly, said end closure including a first wall portion with a third opening extending therethrough, said end closure positioned along said piston assembly such that said third opening is disposed in approximate alignment with said first opening of said end wall of said piston body; a connector fitting extending longitudinally between said end closure and said support post, said connector fitting including a first end disposed in abutting engagement with said end closure and a second end opposite said first end and operatively connected to said support post, said connector fitting including a passage wall extending longitudinally into said connector fitting from along said first end thereof to at least partially define a fitting passage having a passage axis, said passage wall including a first annular groove extending radially outward into said connector fitting; a jounce bumper supported on one of said end closure and said connector fitting, said jounce bumper including:
a bumper body with an end surface dimensioned to abuttingly engage said first end member;a bumper mounting surface facing opposite said end surface of said bumper body; and,a securement pin that extends longitudinally outward beyond said bumper mounting surface in a direction opposite said end surface of said bumper body, said securement pin including a second annular groove disposed therealong and extending radially inward into said securement pin, and said securement pin dimensioned for receipt into said fitting passage such that said first and second annular grooves can be at least approximately aligned with one another; and, a retaining member at least partially received within said first and second annular grooves to retain said jounce bumper on said one of said end closure and said connector fitting such that said jounce bumper is indefinitely rotatable about said passage axis while substantially restricting axial displacement of said jounce bumper to a substantially-fixed axial position relative to said piston assembly during said rotation. |
