Abstract
Official abstract text for this publication.
A pressure vessel includes a pressure vessel body provided with a flow channel through which a fluid is caused to flow, having a rectangular cross-sectional shape, and formed to extend in a direction of flow of the fluid, a body flange provided at at least one end side of the pressure vessel body in a longitudinal direction and having a circular cross-sectional shape, and a connecting member connecting the pressure vessel body and the body flange to each other, and the connecting member has a body-flange connected portion connected to the body flange, having a circular cross-sectional shape, and formed in a cylindrical shape, a pressure-vessel-body connected portion connected to the pressure vessel body, being larger in outer shape than the body-flange connected portion, and formed in a cylindrical shape, and a connecting portion connecting the body-flange connected portion and the pressure-vessel-body connected portion to each other and formed in a cylindrical shape with a shape changing to be gradually smaller from the pressure-vessel-body connected portion toward the body-flange connected portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A pressure vessel comprising: a pressure vessel body provided with a flow channel through which a fluid is capable of flowing, having a rectangular cross-sectional shape, and formed to extend in a longitudinal direction; a body flange provided at at least one end side of the pressure vessel body in the longitudinal direction and having a circular cross-sectional shape; and a connecting member connecting the pressure vessel body and the body flange to each other, wherein the connecting member has a body-flange connected portion connected to the body flange and having a circular cross-sectional shape, a pressure-vessel-body connected portion connected to the pressure vessel body, being larger in cross section than the body-flange connected portion, and having a circular cross section, and a connecting portion connecting the body-flange connected portion and the pressure-vessel-body connected portion to each other and formed in a conical, hemispherical, or semi-elliptical shape with a size changing to be gradually smaller from the pressure-vessel-body connected portion toward the body-flange connected portion, wherein the pressure-vessel-body connected portion is formed such that one end side of the pressure vessel body is insertable and fittable in the pressure-vessel-body connected portion. 2. The pressure vessel according to claim 1 , wherein the body-flange connected portion is formed to extend in the longitudinal direction of the pressure vessel body. 3. The pressure vessel according to claim 1 , wherein the body-flange connected portion is formed to extend in the longitudinal direction of the pressure vessel body, and the body-flange connected portion is provided with a space to dispose a component. 4. The pressure vessel according to claim 1 , wherein the connecting portion is formed in a semi-spherical or semi-ellipsoidal shape. 5. The pressure vessel according to claim 1 , wherein the pressure-vessel-body connected portion is larger in outer shape than the pressure vessel body. 6. The pressure vessel according to claim 1 , wherein the body-flange connected portion is partly inserted and fitted in an opening portion of the body flange. 7. The pressure vessel according to claim 1 , further comprising: a lid member provided with a lid flange, wherein the body flange and the lid flange are fastened with a fastening member.
