Liquid filled vibration isolating device

摘要

This invention is aimed to obtain a liquid filled vibration isolating device, which is able to facilitate assembling procedure without adversely affecting shape or dimension of a caulked portion and without deteriorating mounting performance or reliability, and is able to promote vibration isolating effect both at a low frequency region and at a medium and high frequency region. To achieve this end, the vibration isolating device comprised of a rubber vibration isolating base body that connected with main-body metal fitting; and a two liquid chamber between the vibration isolating base body and a first diaphragm fixed to the main-body partitioned by a partition member and communicated with each other by an orifice; wherein the partition member is comprised of a ring-like partition-plate metal fitting that forms a first orifice, and a rubber orifice member that is attached to inner edge of partition-plate metal fitting and forms a second orifice, and an insert metal fitting butts on the rubber orifice member; and wherein one end of the second orifice is opened to the liquid chamber, other end of the second orifice is occluded by a second diaphragm; and the partition member is fixedly caulked to the main-body metal fitting along with the first diaphragm.
