A dome-shaped pressure vessel (36), contained in a pumping segment (10) for incorporation into a fluid delivery system, with an optimal shape for interfacing with a pressure sensing element (200), and which is capable of uniformly distributing pressure across its interfacing structure (130) and being optimally pre-loaded against the pressure sensing element. The pumping segment (10) includes a lateral restraint (150) to inhibit rupture of the unloaded pressure vessel (36) when experiencing high internal pressures.
L'invention se rapporte à un récipient sous pression en forme de dôme (36), contenu dans un segment de pompage (10) destiné à être incorporé dans un système de refoulement de fluide. Ledit récipient présente une forme optimale pour se raccorder à un élément détecteur de pression (200), permet une répartition uniforme de la pression au niveau de sa structure de raccordement (130) et subit une pré-contrainte optimale à l'encontre de l'élément détecteur de pression. Ce segment de pompage (10) comporte une butée latérale (150) destinée à empêcher, lors de pressions internes élevées, la rupture du récipient sous pression (36) non chargé.
