Abstract:
1. A pressure vessel connection arrangement comprising: a pressure vessel having a substantially continuous wall defining a hollow structure, the hollow structure being on a first surface of the substantially continuous wall, a second surface of the substantially continuous wall provided with a hemi-spherical segment recess configured and disposed to face a complementary hemi-spherical segment recess in a component to which the substantially continuous wall is connected; an alignment configuration between the pressure vessel and the component, in which the hemi-spherical segment recess configured and the complementary hemi-spherical segment recess are face to face; a misalignment configuration between the pressure vessel and the component, in which the hemi-spherical segment recess configured and the complementary hemi-spherical segment recess are not face to face; and one rounded element snugly fitted in a space formed between the hemi-spherical segment recess and the complementary hemi-spherical segment recess, the one rounded element ensuring that the hemi-spherical segment recess and the complementary hemi-spherical segment recess remain in the alignment configuration.
