Vibration isolator with diaphragms in each side wall

摘要: A main liquid chamber communicates with a first auxiliary and second via limiting passage passage, respectively. The chambers are located adjacent air diaphragms, As solenoid valve is changed over, the made to communicate negative pressure of an engine or atmospheric pressure. disposed in hollow cylindrical member. When frequencies vibrations below predetermined frequency, transmitted chamber, causing diaphragm be brought into close contact fixed inner wall chamber. result, passing through absorbs vibrations. become high, becomes incapable absorbing vibrations, imparted For this reason, deformable, so that passes absorb In addition, third accompanying can provided high-frequency length shorter than resonance higher passage.
