Methods and assemblies for retaining an internal component of a valve within an external component thereof using a retention o-ring and groove geometry

Abstract

An example valve includes: an external component having a longitudinal cavity therein, wherein the external component comprises a first annular groove disposed on an interior peripheral surface of the external component, and wherein the first annular groove is bounded by two annular surfaces; an internal component disposed, at least partially, in the longitudinal cavity of the external component, wherein the internal component comprises a second annular groove disposed on an exterior peripheral surface of the internal component, wherein the second annular groove is bounded by two respective annular surfaces, wherein the second annular groove is aligned with the first annular groove, such that the first annular groove and the second annular groove form an annular space therebetween; and a retention O-ring disposed in the annular space formed between the first annular groove and the second annular groove.
