Sealing system of a device for allowing the passage of a medium, in particular in the high pressure range

A sealing system of a device for allowing passage of a medium, comprising:

• a housing having a bore hole defined by a surface, and an annular pressure chamber formed within the bore hole which is chargeable with the medium,
• a component mounted within the housing to oscillate and/or rotate, the surface of the housing defining the bore hole and the component defining the pressure chamber around the component and between an outer surface of the component and the surface of the housing defining the bore hole, and
• a sealing element which surrounds a portion of the component and defines part of the pressure chamber, the sealing element having an inner surface in contact with the outer surface of the component at an end of the pressure chamber,
• wherein a metal seal is formed by the housing and a pressure disc surrounding the component, and so an outer region of the sealing element is tightly closed by the metal seal, and
• wherein the metal seal is formed by two opposing sealing surfaces of the housing and of the pressure disc, an angle of inclination of the opposing sealing surfaces differing from one another by a small angular amount, the opposing sealing surfaces forming a circular sealing edge at an inside edge alongside the bore hole and angling apart from one another in a direction outward from the bore hole.
