- 1. In a pressure accumulator including a rigid shell having an opening at one end thereof, a valve assembly mounted in the opening comprising: a tubular housing having an outer diameter less than the diameter of the opening and having a peripheral shoulder formed at the inner end thereof whose outer diameter is less than the diameter of the opening; a retaining ring formed of a plurality of arcuate segments mounted coaxially around the tubular housing and configured to engage said peripheral shoulder and also to engage the inner surface of the shell surrounding the opening; a resilient ring mounted concentrically around the inner end of the tubular housing and having an outer peripheral surface engaging the inner surface of the shell surrounding the opening, and said resilient ring further having a plurality of wedge-like portions, each extending radially inwardly with increasing transverse dimensions between the segments forming said retaining ring to constitute a mounting means for the resilient ring on the retaining ring.
- 2. The combination defined in claim 1, and which includes an O-ring seal mounted in said opening coaxially around the tubular housing adjacent to the retaining ring; a collar mounted in said opening coaxially around the tubular housing and engaging the O-ring; and a lock nut coaxially threaded to the tubular housing and engaging the collar to mount the valve assembly in the opening in said rigid shell.
