Claim Text:
1. Rotating mechanical seal arrangement for sealing a product side at a rotating component, comprising: a first rotating mechanical seal with a first rotating slide ring and a first stationary slide ring which define a first sealing gap between them; a second rotating mechanical seal with a second rotating slide ring and a second stationary slide ring which define a second sealing gap between them; a fluid space which is limited by the first and second rotating mechanical seals; wherein the first rotating mechanical seal is lubricated with a product medium of the product side, and wherein the second rotating mechanical seal is lubricated with a liquid quench medium of a quench supply unit, the quench medium being located in the fluid space; a quench outlet via which quench medium may be discharged from the fluid space; a gas outlet via which a gas located in the fluid space may be discharged; and a throttle device which is arranged in the fluid space between the first rotating mechanical seal and the second rotating mechanical seal and divides the fluid space into a product-side fluid space region and an atmosphere-side fluid space; wherein the gas outlet is arranged at the product-side fluid space region and the quench outlet is arranged at the atmosphere-side fluid space region, wherein the throttle device includes a rotating ring disk, wherein an orifice of the gas outlet to the fluid space is arranged on a first diameter (D
