PRESSURE DAMPING DEVICE

摘要

A pressure damping device includes a cylinder, a partitioning section, a flow channel formation section, a valve section a bypass channel and a throttle section. The flow channel formation section forms a flow channel, through which the fluid flows, in conjunction with a movement of the partitioning section. The valve section controls a flow of the fluid in the flow channel of the flow channel formation section. The bypass channel forms a flow of the fluid that bypasses the flow of the fluid flowing through the flow channel while opening the valve section. The throttle section that throttles the flow of the fluid through the bypass channel further on an outer side than the valve section with respect to the flow channel formation section.

1. A pressure damping device comprising:
a cylinder that extends from one side toward another side and that houses a fluid; a partitioning section that is provided so as to be movable in an axial direction in the cylinder and that partitions a space in the cylinder into a first chamber and a second chamber; a flow channel formation section in which a flow channel, through which the fluid flows, is formed in conjunction with a movement of the partitioning section; a valve section that controls a flow of the fluid in the flow channel of the flow channel formation section; a bypass channel that forms a flow of the fluid that bypasses the flow of the fluid flowing through the flow channel while opening the valve section; and a throttle section that throttles the flow of the fluid through the bypass channel further on an outer side than the valve section with respect to the flow channel formation section.
