ABSTRACT:
A slide ring seal assembly includes first and second machine components each having an annular clamping face coaxial with the rotary axis of the assembly; and first and second slide rings including respective inner and outer peripheral clamping faces each surrounding the assembly axis. The slide rings together define an annular sliding surface surrounding the assembly axis. First and second elastic sealing rings are compressed between the respective clamping faces of the machine components and the slide rings. The first sealing ring and the clamping face of the first machine component together define a first sealing area and the second sealing ring and the clamping face of the second slide ring together define a second sealing area. Each sealing area is bordered by a boundary line distal from the annular sliding surface and by a boundary line proximal to the annular sliding surface. An imaginary line lying in a plane containing the assembly axis and connecting the distal boundary line of the first sealing area with the proximal boundary line of the second sealing area intersects the annular sliding surface approximately at a midpoint of its radially measured width.
