PROBLEM TO BE SOLVED: To damp engine idling vibration composed of a low frequency by high damping force. SOLUTION: This liquid sealed type vibration control device is composed of an insulator 3 for cutting off vibration from a vibrating body, a main chamber 5 forming a chamber wall out of a part of the insulator 3 and sealing liquid, an auxiliary chamber 6 forming a part of the chamber wall out of a first diaphragm 4 opposed to this main chamber and communicating with the main chamber 5 by a first orifice 7, a second orifice 9 of a double winding form for communicating the auxiliary chamber 6 with a third liquid chamber 8, an orifice forming member 11 forming the first and second orifices, and a liquid chamber forming member 12 forming the third liquid chamber 8 in its inside central part and provided with a second diaphragm 20 for defining a part between the liquid chamber and the main chamber 5. A partition wall 93 between inside-outside passages 9a and 9b of the second orifice 9, is formed of a rubber-like member. COPYRIGHT: (C)2006,JPO&NCIPI |
