CLOSURE DEVICE FOR STREAMING MEDIA, IN PARTICULAR HIGH PRESSURE LIQUIDS

摘要

It is known to construct a closure means for high pressure fluids in such a way that the forces acting on it compensate each other. According to the invention such a closure means is improved in such a way that it can be removed from the path of the closure means, in order to allow a free streaming of the fluid. For this purpose the closure means is either moved in the interior of the casing, or it surrounds the casing like a sleeve.
