Patent number: 11255417Abstract: A hydrodynamic coupling arrangement has a housing connected to pressure medium lines for conducting pressure medium into or out of a pressure space sealed by a piston of a clutch device relative to a toroidal space of a hydrodynamic circuit provided in the housing. A rotatable area is provided for axially displaceably receiving a radially inner piston hub of the piston of the clutch device, and at least one through-opening which is rotatable relative to the housing is provided in a through-opening area for producing at least one flow connection between at least one pressure medium line and the pressure space.
