LIQUID SEALING TYPE VIBRATION ISOLATION DEVICE

摘要

PURPOSE:To obtain an excellent vibration attenuating property by cutting off a burr of an elastic body so as to prevent a generation of flowing resistance of a liquid passing through an orifice. CONSTITUTION:While an elastic body 4 furnishing a recess 5 at the upper end 4a is provided on the outer peripheral surface of an inner tube 3 surrounded by an outer tube 1 in a concentrical condition, a partition plate 10 to partition the above recess 5 into a main liquid chamber 8 and a sub-liquid chamber 9 is provided, and furthermore, a hard quality of circular arc form installing member 21 furnishing an orifice 11 to replace and let flow the operating liquid in the main and the sub-liquid chambers 8 and 9 at the periphery is provided. And furthermore, cutters 23 and 23 at both ends 22a and 22b of the main body 22 of the installing member 21 have been extended in the direction of the upper end 4a of the elastic body 4 positioned higher than the outer end edges 4d and 4e of the connection of the elastic body 4.
