Pressure tank i.e. hydrogen tank, for gaseous medium i.e. hydrogen, in motor vehicle, has extraction device and ring-like seal that exhibits triangular cross-section, where seal is pressed on stop surface

摘要

The tank (1) has an extraction device (2) i.e. cylinder valve, and a ring-like seal that exhibits a triangular cross-section. The seal made of polyetheretherketone material is pressed on a stop surface (6). The seal is arranged for the tank and/or the device during screwing the tank with the device over a thread such that a compression force in a radial direction (P) is caused due to a bent side surface of the seal by screwing the device in an axial direction. The seal having an isosceles shape has side pieces (5, 5a) with a right angle. A sealing surface is formed at the tank.
