摘要： A liquid sealed vibration isolating device has an elastically movable diaphragm capable of preventing elastic deformation of a relief valve to realize high damping while preventing a cavitation phenomenon. The relief valve is provided in the elastic movable diaphragm arranged in a partition member in order to open and close a leak passage so as to prevent occurrence of the cavitation phenomenon. The relief valve is integrally formed with a fixing portion of the elastic movable diaphragm. There is provided an upwardly open concavity that the relief valve faces. The relief valve is made thicker and provided with an opening and closing adjustment groove at a basal portion of its inclined wall. The opening and closing adjustment groove is formed with a locally thin bending portion functioning as a starting point of bending in an opening and closing operation of the relief valve.

摘要： To form a relief valve for preventing the generation of the cavitation phenomenon into a simple and accurately operable structure, there are provided a central thin wall portion and a fixing portion in an elastic diaphragm provided in the partition member to have the fixing portion fixed in position. A relief valve is integrally formed with an outer peripheral portion of the fixing portion. The relief valve is provided with an inclined surface formed on the side of a secondary liquid chamber and a recessed portion opened on the side of a primary liquid chamber and has a difference in rigidity in the circumferential direction. When the primary liquid chamber turns negative pressure, a hydraulic liquid in the secondary liquid chamber opens the relief valve and leaks to the primary liquid chamber so as to prevent the generation of the cavitation phenomenon.

摘要： To block the transmission to a vehicle body side of the vibration due to the cavitation phenomenon occurred in a primary liquid chamber so as to prevent the generation of noises, at the same time, to make the device compact, and to improve the fitting accuracy to obtain the reliable positioning, a first metallic fitting and a second metallic fitting are connected by an insulator. A primary liquid chamber and a secondary liquid chamber formed inwardly are partitioned by a partition member and communicated therebetween by an orifice passage. The partition member is floatingly supported between an extended portion of the insulator and an outer peripheral thick wall portion of a diaphragm, and the tuning is performed to generate the rigid resonance at the predetermined frequency. An outer ring is provided in the outer peripheral thick wall portion so as to be securely fixed by a fixing portion formed by bending an end of an outer cylindrical fitting. The floatingly supporting structure does not become large-sized and complicated since the partition member is simply floatingly supported.
