LIQUID SEALED VIBRATION ISOLATOR

摘要

PROBLEM TO BE SOLVED: To provide a liquid sealed vibration isolator improved in service life of rubber walls forming liquid chambers. SOLUTION: A pair of rubber-like elastic bodies 8 positioned in both sides of an inside cylinder 1 are interposed between the inside cylinder 1 and an outside cylinder 2, and a pair of liquid chambers 4 and an orifice 5 for communicating both the liquid chambers 4 with each other are formed between the inside cylinder 1 and the outside cylinder 5. The liquid chamber 4 is a liquid sealed vibration isolator formed by separately covering between both the rubber-like elastic bodies in the circumferential direction of the inside and the outside cylinders 1 and 2 with a pair of opposite rubber walls 10 from both the axially outward sides of the inside and outside cylinders 1 and 2. One rubber wall 10A is curved for projection toward the other rubber wall 10B side, and the other rubber wall 10B is curved for projection toward the one rubber wall 10A. COPYRIGHT: (C)2004,JPO
