FLUESSIGKEITSREIBUNGSSKUPPLUNG.

摘要

In a viscous fluid coupling the space between first, second and third relatively rotatable members (4, 5, 3) is divided by a wall (10) into two operating chambers (11, 12) containing viscous fluid. A pump (13) moves fluid between the two chambers (11, 12) when there is relative rotation between the first and second members (4, 5).
