Filling end fitting for use in e.g. cylindrical gas tank filled with e.g. natural gas in e.g. road vehicle, has central body or flange body including blocking unit that is rotated around longitudinal axis with respect to inner liner

摘要

The fitting has a central body or a flange body (3) extending along a longitudinal axis (X) perpendicular to a wall of a gas tank in an anchoring area (4) of an inner liner (1). The central body or the flange body is partly drowned in the anchoring area of the inner liner by rotational molding. The central body or flange body includes a rotational blocking unit (11) that is rotated around the longitudinal axis with respect to the inner liner. The central body or flange body is made of metallic material.
