Patent ID: 8783280

Claim:
A mechanical energy dissipation system for dissipating hydraulic hammer action in a moving tank containing a liquid load, having a rupture disk assembly for allowing some of the liquid load to escape from the tank before the tank is fractured from the hydraulic hammer action or BLEVE, comprising: a mechanical device of a relatively small size in comparison to the size of the tank, said device being sized and shaped to be located in the line of flow between the rupture disk of the rupture disk assembly and the liquid load, in the tank, said device when located in the line of flow presenting impact surfaces to the liquid flow from the tank to the rupture disk, dissipating the hydraulic hammer action of the liquid as it flows through said device, wherein said device includes a tubular body portion and a flange portion, and the tubular body portion is neither welded to the flange portion nor cast as a unitary unit with the flange portion, and wherein the tubular body portion is attached to the flange portion with a press fit and a snap ring.
