DEVICE FOR BUFFERING THE CLOSING IMPACT OF FURNITURE DOORS

摘要

Disclosed herein is a device for buffering the closing impact of furniture doors. A valve (40) is mounted around a piston rod (23) of a piston (20) in such a fashion that an oil gap (41) is defined between the outer peripheral surface of the valve (40) and the inner peripheral surface of a cylinder (10), the valve having a recessed oil passageway (47) formed on an axial end surface thereof. A protrusion element (50) is integrally formed with a front end portion of the valve (40). The protrusion element (50) has a plurality of oil grooves (51) formed longitudinally on the outer periphery thereof. A check valve (60) is mounted on the outer circumferential surface of the protrusion element (50) in such a fashion as to slidingly reciprocate along the compression direction of oil. whereby when an external load is exerted to the piston (20), the check valve (60) moves along with the protrusion element (50) and simultaneously oil contained in the oil chamber (11) flows through the recessed oil passageway (47) of the valve (40) and the oil gap (41) via the oil grooves (51) defined between the protrusion element (50) and the check valve (60) to thereby absorb an impact generated during the closing of the furniture door.
