Abstract
A rotary damper comprises a housing, a disc-shaped rotor which is supported within the housing so as to be rotatably and axially displaced in the housing, the rotor including an axially aligned annular friction surface which coacts with a coaxial annular friction surface inside the housing, and a spring within the housing which axially presses the rotor against the friction surface of the housing.
