ABSTRACT:
In a bimetal-actuated damper a loop-shaped bimetal element engages a damper element. One end of the loop is fixedly fastened while the other end of the loop is movably connected with the damper element. This improves temperature-dependent response and sensitivity of the damper and prevents damage from overheating or permanent change of operating characteristics.
