Patent ID: 8413994

Claim:
A sealing system between two mutually moving components for sealing a high pressure side with respect to a low pressure side, wherein an outer component has a sealing configuration annular groove opening towards an inner component and facing the low pressure side and a first annular groove opening towards the inner component and facing the high pressure side, the sealing system comprising: a sealing configuration disposed in the sealing configuration annular groove, said sealing configuration having a sealing configuration sealing ring seating on the inner component and made from an elastically deformable material as well as a sealing configuration preloading ring radially surrounding said sealing configuration sealing ring and sealing the sealing configuration annular groove, the sealing configuration preloading ring made from an elastically deformable material; and a first pressure relief element disposed in the first annular groove, said first pressure relief element having a first sealing ring seating on the inner component and made from an elastically deformable material as well as a first preloading ring radially surrounding said first sealing ring and sealing the first angular groove, said first preloading ring made from an elastically deformable material, wherein said first pressure relief element has at least one first connecting channel associated therewith by means of which a first intermediate space, disposed between said sealing configuration and said first pressure relief element, is connected to the high pressure side, wherein each said first connecting channel is closed in a pressure configuration P ZA <P H and is open in a pressure relief configuration P ZA ≧P H +P Acrit , wherein P H is the hydraulic pressure on the high pressure side, P ZA the hydraulic pressure in said first intermediate space and P Acrit a pressure increase quantity which, when exceeded, leads to opening of said first connecting channel, wherein P Acrit is defined by deformation of said first preloading ring in an axial direction.
