APPARATUS FOR REDUCING VIBRATION OF HYDRAULIC BREAKER

摘要

The present invention relates to a vibration reducing device of a hydraulic breaker comprising: a housing installed around an excavation tool; a cylinder installed in the housing; a damper piston capable of reciprocating in the cylinder; a beam vertically moving the damper piston in the cylinder when the excavation tool moves in a vertical direction by being connected between the damper piston and the excavation tool by a pin joint; and a working fluid filling an inside of the cylinder. The present invention efficiently reduces a vibration of the excavation tool using a hydraulic damper without significantly changing a form of an existing breaker.
