Beschreibung
Zusammenfassung:	The invention relates to a mechanical seal arrangement, in particular a retarder-mechanical seal arrangement, comprising a first mechanical seal (2) with a first rotating slide ring (3) and a first stationary slide ring (4) which define a first sealing gap (5) in between them, an additional seal (6), a cooling medium space (7) which is filled with a cooling medium and extends all the way to the sealing gap of the first mechanical seal (2), wherein the first mechanical seal (2) seals the cooling medium space against an environment, a cooling medium access (8) into the cooling medium space (7) for supplying cooling medium, and a cooling medium exit (9) from the cooling medium space (7) for draining cooling medium, wherein the additional seal (6) is arranged in the cooling medium access (8), and wherein the additional seal (6) is configured to open when a pressure inside the cooling medium access (8) rises above a first pressure (P1) inside the cooling medium space (7), and to close at a second pressure (P0) inside the cooling medium access (8) that is lower than the first pressure (P1) inside the cooling medium space.
