Flexible spring member and end closure assemblies (FEA) include a flexible spring member (200) defining a spring chamber (202). An end closure body (502) includes an outer peripheral surface portion (512) and an elongated damping passage (522) extending axially into end closure wall (506) in a spiral arrangement about longitudinal axis (AX). End closure body (502) is positioned along an end (208) of flexible spring member (200) with flexible wall (204) permanently attached along outer peripheral surface portion (512) such that a substantially fluid-tight joint is formed between flexible spring member (200) and end closure body (502). Gas spring and gas damper assemblies (AS1) as well as methods of assembly are also included.

    L'invention concerne des ensembles fermeture d'extrémité et élément ressort flexible (FEA) comprenant un élément ressort flexible (200) délimitant une chambre de ressort (202). Un corps de fermeture d'extrémité (502) comprend une partie de surface périphérique externe (512) et un passage d'amortissement allongé (522) s'étendant axialement dans une paroi de fermeture d'extrémité (506) dans un agencement en spirale autour d'un axe longitudinal (AX). Le corps de fermeture d'extrémité (502) est positionné le long d'une extrémité (208) d'un élément ressort flexible (200) avec une paroi flexible (204) fixée de façon permanente le long de la partie de surface périphérique externe (512) de telle sorte qu'un joint sensiblement étanche aux fluides soit formé entre l'élément ressort flexible (200) et le corps de fermeture d'extrémité (502). L'invention concerne également des ensembles amortisseur à gaz et ressort à gaz (AS1) ainsi que des procédés d'assemblage.
