Abstract
An economical to manufacture and simple to install and remove gas charged fluid pressure accumulator including a cup-shaped accumulator body with an integral dome at one end and an integral in-turned annular lip at the other end, a piston slidably disposed in the accumulator body, and an external screw thread on the accumulator body. The accumulator body is screwed into a threaded counterbore until the annular lip bears against a bottom wall of the counterbore with a fluid port of the manifold inside of the projection of the lip on the bottom wall. A seal ring in a groove in the bottom wall of the counterbore bears against the annular lip to seal the chamber of the accumulator defined between the bottom wall and the piston.
