摘要： PROBLEM TO BE SOLVED: To provide a further compact and inexpensive hydraulic circuit, causing no operational anxiety on the risk side, capable of exhibiting superior and stable performance, and capable of exhibiting effectiveness even from a microvibration level, in a damping coefficient switching type hydraulic damper capable of always reliably exhibiting energy absorbing capacity exceeding an ordinary hydraulic damper, while automatically switching a damping coefficient without requiring external energy supply at all.
SOLUTION: The damping coefficient switching type hydraulic damper uses pressure stored in a buffer 21 for driving force of an opening-closing valve 6. The buffer 21 and a low pressure accumulator 7 are connected by a flow passage having a switching valve 42. The switching valve 42 is automatically switched by differential pressure between right-left hydraulic chambers, and opens in a neutral position when the differential pressure between the right-left hydraulic chambers becomes zero, and reliably prevents a malfunction on the dangerous side where the opening-closing valve 6 continuously maintains an open state when pressure remains in the buffer 21 by completely releasing hydraulic pressure in the buffer 21.
