|1. (WO2018163444) PRESSURE BUFFERING DEVICE|
|Title:||PRESSURE BUFFERING DEVICE|
This pressure buffering device is provided with: a cylinder which houses a fluid; a piston which forms a flow path through which the fluid flows accompanying a rod moving in a prescribed direction relative to the cylinder; a valve which is elastic and which opens and closes the flow path of the piston; a movement permitting unit which permits moving the valve position between a contact position contacting the piston and a withdrawn position spaced away from the piston; a limiting unit which limits flexural deformation of the valve in the withdrawn position; and an applying unit which is elastic and applies to the valve a weight that is unequal in the circumferential direction of the valve and that is directed towards the piston.
