Abstract
A dry rotary damper includes a housing defining an internal chamber, the housing having a closed base portion, a top portion with a through opening, and a rotor-engaging internal surface. A rotor has a shaft rotatably passing through the opening and an engagement surface in sliding frictional engagement with the rotor-engaging internal surface of the housing. A deflection member is mounted within the chamber. An edge part of the deflection member impinges upon the rotor and the deflection member is deflected for resiliently urging the engagement surface into frictional engagement with the rotor-engaging internal surface of the housing.
