Title:
ROTARY DAMPER, AUTO PART HAVING ROTARY DAMPER AND ROTATIONAL MOTION ASSISTANT MECHANISM
Document Type and Number:
Japanese Patent JP2009103306
Kind Code:
A
Abstract:

To provide a rotary damper capable of automatically adjusting exhibited braking force in correspondence with a variation in a load.

A fluid chamber 2 filled with a viscous fluid is formed in a casing 1, and a vane 3 is disposed in this fluid chamber 2. The vane 3 is formed with a fluid passage 5, and is provided with a valve 6 for automatically varying a flow rate of the viscous fluid passing through this fluid passage 5 in correspondence with a variation in the load. With this constitution, it is possible to automatically adjust the exhibited braking force in correspondence with the variation in the load caused by a variation in the rotational moment of a control object, to reduce a variation in a rotation speed of the control object to an extremely small value.
