摘要： PURPOSE:To effectively reduce shake as well as shoveling vibration by providing a wall body with large expansion elastic modulus on the outside of a rubber vibration isolator, by forming a pressure chamber between this wall body and the rubber vibration isolator, and by changing internal pressure of the pressure chamber according to vibration input. CONSTITUTION:When shake vibration is detected, a pressure changing device 3 returns liquid in a pressure chamber P, a wall body 2 is made freely deformable, and a rubber vibration isolator 1 is deformed accompanying vibration input. Then, as liquid in a main liquid chamber A flows to an auxiliary liquid chamber B via a contracted flow passage F, a vibration damping force is generated. When shoveling vibration is detected, the pressure changing device 3 supplies liquid to the pressure chamber P and expands the wall body 2, but when it is expanded to a certain extent, the expansion is prevented by a cloth 21, and expansion elastic modulus gets larger. At this time, the rubber vibration isolator 1 is deformed downward and internal pressure in the main liquid chamber A is increased so as to seal the liquid in the pressure chamber P. In this state, apparent expansion elastic modulus of the rubber vibration isolator 1 gets larger due to contribution of the expansion elastic modulus of the wall body 2, damping peak is moved to the low frequency side, and a damping coefficient of the shoveling vibration zone gets larger.

摘要： PURPOSE:To aim at the damping of large magnitude vibration and the absorptive abatement of high-frequency vibration by installing a main liquid chamber making a vibration proof rubber body of its chamber wall, a sub-liquid chamber making a rubber sheet of its chamber wall and a throttle passage interconnecting these chambers all in a cylinder body, and making a vibration reed and a thin-wall part of the chamber wall jut out to the inside of the main liquid chamber, respectively. CONSTITUTION:When large magnitude vibration of low frequency is inputted, an inner cylinder 1 is largely subjected to relative displacement with an outer cylinder 2 whereby volume of a main liquid chamber A varies, and a sealed liquid flows into a sub-liquid chamber B via a throttle passage 51. At this time, periodic damping is carried out by flow resistance received by the sealed liquid and liquid resonance of the sealed liquid in the throttle passage. On the other hand, a volumetric change in the main liquid chamber A is little to a small magnitude vibration of high frequency. In this case, the sealed liquid existing between chamber walls of a tip of a vibration reed 61 and the main liquid chamber A produces liquid resonance by this vibration reed 61 vibrating as one body with the inner cylinder 1, thus this liquid resonance serves as a vibration absorptive action. Since this liquid resonance is effectively produced because a part of the chamber wall is formed into a thin-wall part 31.
