380SL (107.045) V8-3.8L (116.960) (1982)
the result that the transfer bore is gradually exposed and the circulation of the viscous oil is re-established (A, cut-in position).
With decreasing coolant temperature the bimetallic strip (1) will gradually cool down and its changing shape will increasingly displace the spring plate
(3) by way of the pin (2) in the direction of the primary disk (4) until the spring plate closes the transfer bore (5) not later than at a coolant temperature of
approx. 95 °c The circulation of the viscous oil is interrupted, the viscofan clutch will disengage.
