ABSTRACT:
An adjustable high torque damper device is provided which can be easily and rapidly adjusted so as to produce variable amounts of torque over a predetermined range. The damper device includes a plurality of co-mating concentric rings formed on a stator housing and a rotor. As a cap is screwed into or out of the housing, the distances between the rotor concentric rings and the stator concentric rings are selectively and gradually increased and decreased to thereby decrease or increase the amount of torque.
