Title:
OIL DAMPER SYSTEM
Document Type and Number:
Japanese Patent JP2023108941
Kind Code:
A
Abstract:
To provide an oil damper system which enables improvement of maintainability of an oil damper whose damping performance is changed.SOLUTION: A damping valve unit 10 is provided at a uniflow type cylinder unit, has a valve body 14 which is biased by a pressure-adjusting spring 16, and is configured to absorb energy through action in which a working fluid F flowing from a working fluid outflow chamber of the cylinder unit to an outer cylinder moves the valve body against a spring force. The pressure-adjusting spring of the damping valve unit is formed as return means which returns a control oil f to control cylinder units so that control piston rods are respectively returned to initial positions.SELECTED DRAWING: Figure 4
