| description | PROBLEM TO BE SOLVED: To provide an active damper that can prevent vibration transmission from an unsprung part (supporting frame) to a sprung part (damping object) in a high frequency range where a response of a pump motor cannot be followed, without increasing extra control or unnecessary loss in a conventional manner.SOLUTION: An active damper includes a hydraulic cylinder interposed between a damping object and a supporting frame; a hydraulic pump discharging hydraulic fluid to the hydraulic cylinder; a pump motor driving the hydraulic pump; and an accumulator connected to a hydraulic-oil supply channel in communication between the hydraulic cylinder and the hydraulic pump. |
