DOME-SHAPED PRESSURE VESSEL AND METHOD FOR OPTIMIZING SAME

摘要

A pumping segment for incorporation into a fluid delivery system, the segment having a dome-shaped pressure vessel with an optimal shape for interfacing with a pressure sensing element, and which is capable of uniformly distributing pressure across its interfacing structure and being optimally pre-loaded against the pressure sensing element. The pumping segment including a lateral restraint to inhibit rupture of the unloaded pressure vessel when experiencing high internal pressures.
