Title (EN) VIBRATION-PROOFING DEVICE
(FR) DISPOSITIF ANTIVIBRATION
(JA) 防振装置
Abstract:
(EN) This vibration-proofing device comprises: a cylindrical body connected to a vibration receptor; a supporting body connected to a vibration generator; an elastic body by which the supporting body is mounted so as to be relatively movable to the cylindrical body; a first liquid chamber which is defined by an orifice passage and the elastic body; a second liquid chamber which communicates with the first liquid chamber through the orifice passage and circulates liquid therebetween; a first gas chamber with a diaphragm as a wall portion; a second gas chamber which is capable of communicating with the first gas chamber; and a switching portion which switches the communication state between the first gas chamber and the second gas chamber.
(FR) Dispositif antivibration comprenant : un corps cylindrique relié à un récepteur de vibrations ; un corps de support relié à un générateur de vibrations ; un corps élastique par lequel le corps de support est monté de manière à être relativement mobile par rapport au corps cylindrique ; une première chambre de liquide qui est délimitée par un passage d'orifice et le corps élastique ; une seconde chambre de liquide qui communique avec la première chambre de liquide par le biais du passage d'orifice et fait circuler du liquide entre celles-ci ; une première chambre à gaz ayant une membrane en tant que partie de paroi ; une seconde chambre à gaz qui peut communiquer avec la première chambre à gaz ; et une partie de commutation qui commute l'état de communication entre la première chambre à gaz et la seconde chambre à gaz.
(JA) 防振装置は、振動受部に連結される筒体と、振動発生部に連結される支持体と、支持体を筒体に相対移動可能に取付ける弾性体と、オリフィス通路と弾性体で区画された第1液室と、オリフィス通路を介して第1液室との間で液体が流通する第2液室と、ダイヤフラムを壁部とした第1気体室と、第1気体室と連通可能な第2気体室と、第1気体室と第2気体室の連通状態を切り替える切替部とを有する。
