PURPOSE:To cause a liquid-column resonance to a high-frequency vibration, forming a low-motion spring characteristics as well as to form a high damoing characteristic by means of flow resistance in an orifice to a low-frequency vibration, respectively. CONSTITUTION:A movable part 1 integrally formed with an upper connecting fitting 7 is installed in a main chamber 81. This movable part 1 consists of a rod 12, a disk part 11, a flange part 19, a piston 15 or the like, In addition, linkage 5 consisting of a lever 3 or the like to be engaged with the flange part 19 of this movable part 1. A cylinder part 85 with an intake port 89 being opened in the main chamber 81, while the piston 15 is inserted into, is installed therein. This cylinder part 85 is connected to an orifice 88 which is, in turn, connected to a sub-chamber 82. With this constitution, a low-motion spring constant is formed against a close noise, whereby a vibration is interrupted. Likewise, a high damping characteristic is formed against a engine shake, whereby the vibration is checked. |
