Abstract
Provided is a pressure vessel intended for storing up a fluid having high pressure, and more specifically, to a pressure vessel capable of enabling a sealing pad made of an elastic material to effectively prevent the fluid from flowing out from a bonding portion of a nozzle and a liner. The pressure vessel includes: a liner formed to be hollow so as to enable its inside to be filled with the fluid; a nozzle combined with one side of the liner, or each end portion of both sides so as to enable a coupling part having a cylindrical shape to be located in the inside of the liner; a sealing pad having a ring-like shape configured to enable the coupling part to pass through its center, and formed of an elastic material; and a sealing nut coupled to the coupling part from a lower portion of the sealing pad.
