ABSTRACT:
A hydraulic coupling is provided which has a primary blade wheel and a secondary blade wheel confining an operating space, said primary wheel having a first delay chamber connected by channels with the operating space located relatively close to the coupling axis and a second delay chamber, predominantly located further away from the coupling axis than the radially outer limitation of the operating space, the second delay chamber being connected with the operating space by large diameter ports, preferably by the radially outer annular gap between the blade wheels.
