Title:
DAMPER
Document Type and Number:
WIPO Patent Application WO/2020/149224
Kind Code:
A1
Abstract:
The present invention is such that during a reverse step, a check valve seated in an annular seat part (second seat part) is quickly opened, whereby a working fluid in a downstream chamber can be quickly introduced into a back-pressure chamber. Therefore, it is possible to suppress response delays in damping force due to the check valve sticking to a relief valve.
