Abstract
A temperature compensated fluid filled damper is provided which in a preferred embodiment is a rotary damper which includes a housing for receiving a rotor having a surface for engaging a viscous fluid sealed within the housing. The housing includes a temperature compensating member positioned adjacent the rotor surface and which is made of a material which has a coefficient of thermal expansion different than that of the rotor to provide a varying gap width between the surface of the rotor and the temperature compensating member such that as the temperature changes the drag provided to the rotor by the gap change varies inversely to the drag provided by the viscous fluid.
