Abstract
A slide ring seal for sealing a machine component relative to a pressurized media. A slide ring is provided which is axially slidably mountable on the machine component. A bellows is arranged for surrounding an axial portion of the machine component. The bellows has one axial end connected with the slide ring and a second axial end. The bellows includes a sealing member at the second axial end for sealing the machine component with respect to the pressurized media. The bellows has a region between the slide ring and the sealing member which, in a relaxed state of the bellows, has a shape approximately corresponding to the contour of the region that will develop when the bellows is subjected to operating pressures in an installed state of the slide ring seal. A compression spring is arranged to be concentrically mounted on the machine component with respect to the slide ring and the bellows and is disposed between the slide ring and the sealing member.
