Title:
DAMPER DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/037007
Kind Code:
A1
Abstract:
A damper device is provided with a cylinder body and a piston body and, by mounting either the cylinder body and/or the piston body to an object to be damped, damps the movement or relative movement of the object to be damped. A communication hole for connecting the inside and outside of the cylinder body is formed in a portion located deep inside the cylinder body. The damper device is also provided with a valve element. The valve element moves from a reference position while allowing at least a part thereof to be deformed by a pressure change caused by the movement or relative movement of the piston body, and by doing so, the valve element reduces the flow rate of fluid passing through the communication hole.
