Damper having silicone impregnated and silicone containing components
Abstract:
A damper for damping movement of an object is formed from silicone impregnated or silicone containing components. The damper includes a housing having walls defining a well and a rotor positioned in the housing within the well. The rotor is positioned to define a space between the rotor and the walls. One or more seals is positioned between the housing and the rotor to isolate the space from the environment. A damping fluid is present in the well between the rotor and the housing for damping rotation of the rotor relative to the housing. The housing, the rotor and the seals are formed from silicone containing or silicone impregnated materials. The damping fluid is also a silicone based material.
