Vibration isolating apparatus

摘要

A partitioning member (28) is disposed within an outer cylinder metal fitting (16). A space which is defined by the partitioning member and an elastic body forms a main liquid chamber (30). The main liquid chamber and a first auxiliary liquid chamber (32) are disposed with the partitioning member therebetween. A shake orifice (64) and an idle orifice (60) are formed at the partitioning member and the idle orifice is opened and closed by a rotor. A second diaphragm (82) is disposed at the first auxiliary liquid chamber side and a clearance between the second diaphragm and the lower surface of the partitioning member forms a second auxiliary liquid chamber (86). When shake vibration which is low frequency vibration is generated, the vibration is damped and absorbed by the shake orifice. When idle vibration is generated, the idle orifice is opened and the high frequency vibration is absorbed. <IMAGE>
