Talk:Fluid coupling

Vulcan-Sinclair
I had always assumed that the Vulcan-Sinclair hydraulic coupling (popular on early British diesel locomotives) was a product of the Vulcan Foundry in England. However, it appears that it was actually A. G. Vulcan in Germany. I don't know enough German to translate the German Wikipedia articles but, if somebody else can, it would be interesting. The relevant articles are. Biscuittin (talk) 18:19, 15 November 2009 (UTC)

Hello! I want to shop a fluid hydraulik coupling Type MD 32 and power 24 kW ,1460RPM with capacity 5.2 L I want to know how much are the price Best wishes Mahir Mahir Alhaydar (talk) 13:48, 29 January 2019 (UTC)

Slip - Efficiency
"The very best efficiency a fluid coupling can achieve is 94 percent" Where does this 94 percent number comes from??? Shouldn't this be completely dependend on the actual slip, used fluid, construction and size of the coupling, etc. ?? GuntherS (talk) 14:24, 8 May 2012 (UTC)
 * This is a theoretical limit. Issues like fluid internal friction reduce the actual efficiency down from this figure.
 * The proof isn't simple, but does deserve inclusion. It might be in Fottinger's patents, or it will be in a decent undergrad-level fluid dynamics textbook. Andy Dingley (talk) 16:00, 8 May 2012 (UTC)

Hydrokinetic?
The device being discussed is formally known as a hydrodynamic coupling. The term “hydraulic coupling” is ambiguous as best, as it doesn’t differentiate between hydrodynamic and hydrostatic.
