US 11,598,482 B2 · High-pressure vessel

Abstract

A high-pressure vessel that includes a cylinder, at least one half-shell, and a substantially rotationally symmetrical insert member. The cylinder, forming a middle region of the high-pressure vessel, is composed of a multilayer composite plastic having a first barrier layer. The at least one half-shell is formed at an axial end of the cylinder, and is composed of a multilayer composite plastic having a second barrier layer. The substantially rotationally symmetrical insert member has a foot member at an end thereof which faces an interior of the high-pressure vessel. The foot member has a diameter that is greater than a diameter of a middle region of the insert member. The foot member is configured to substantially form a hollow cone or hollow cylinder and at least a first groove or recess filled with the multilayer composite plastic of the at least one half-shell, and which is configured to extend around at least in certain portions on an inner circumference of the foot member.
