The invention concerns a hydrodynamic coupling, The invention is characterized in that the storage chamber is designed as a confined chamber which is pressure-tight to the environment, having a control pressure port so as to forcibly displace the working medium in the storage chamber with a control pressure.

Hydrodynamic coupling

The invention concerns a compression device fitted with a drive unit; with a compressor driven by the drive unit, which compresses a gaseous compression medium; with a cooling device, comprising at least one fan wheel, which cools the compression medium; the fan wheel is in drive connection with the drive unit or a second drive unit additionally provided, in order to be thereby driven in rotation. The invention is characterized in that a hydrodynamic clutch is arranged in the drive connection, via which the fan wheel is driven hydrodynamically, and the drive power transmission of the hydrodynamic clutch can be modified in operation by pressurizing the hydrodynamic clutch with a control pressure medium, wherein the compression medium is the control pressure medium at the same time.
