Protection device of a control spring of a rotating member

摘要

The guard esp. for a spring (5) between a rotary arm (1) and a flange (4) , consists of a sleeve (9) which surrounds the spring and forms a sealed housing around it between the arm and flange. In a variant of the design, the sleeve can be made in one piece with the arm or the flange. The ends of the spring are turned outwards to form two pins (6,7) which engage with corresponding holes in the arm and flange, and the sealed housing formed by the sleeve can be filled with grease.
