Abstract
A rotary retardation device utilizing viscous fluid responsive to angular velocity in which the viscous fluid is retained in a cavity, one wall of which is a flexible deformable member, the fluid being sealed in the cavity, and a relatively movable rotary member bearing on the flexible member in a moving path to respond in rotation to the action of the viscous fluid in the cavity.
