Abstract
A viscous fan coupling unit is controlled by a bimetallic strip. The bimetallic strip is subdivided by an elongate slot into two partial strips. The partial strips are interconnected by end portions of the bimetallic strip and by a cross-piece. The cross-piece acts on a control pin of the viscous fan coupling. This bimetallic stream reacts immediately on temperature changes of the air strip passing around the bimetallic strip. By the slot internal stresses are avoided such that the bimetallic strip can provide larger deflection paths and larger control forces in response to temperature changes.
