Title:
LIQUID-SEAL VIBRATION ISOLATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/067992
Kind Code:
A1
Abstract:
A suspension type liquid-seal vibration isolating device, wherein a support load is exerted to a second installation member (12) disposed inside a tubular first installation member (10) in such a direction that the member (12) is extracted in axial direction, a partition part (30) partitioning a lower side main liquid chamber (32) from an upper side auxiliary liquid chamber (34) is formed of a piston-like member (36) and a cylinder-like member (38) displaceable so as to vary the volumes of both liquid chambers (32) and (34) according to the elastic deformation of a vibration isolating base body (14) when vibration is applied thereto to develop a vibration isolating performance in a wide frequency range, MR fluid (40) having a viscosity varying according to the intensity of a magnetic field is sealingly held between both the piston-like member (36) and the cylinder-like member (38), and an electromagnet (46) capable of controlling the intensity of the magnetic field is installed in the piston-like member (36).
