<p>PURPOSE:To improve an anti-vibratory characteristic in a range of high frequency in an anti-vibratory supporter applied as an engine mount and etc. by a method wherein liquid is poured into a major sealed chamber and sub-sealed chamber made of rubber resilient means and a movable partition wall is arranged between both chambers. CONSTITUTION:Major sealed chamber 4 is formed in the cylindrical rubber resilient means 3 provided, at its both ends, with one fixing fitting 1 connected to a schassis and another fixing fitting 2 connected to the engine. Sub-sealed chamber 6 enclosed by an enclosure 5 made of rubber resilient means is formed at a side opposite to the fixing fitting 2 and the major sealed chamber 4, then liquid 7 is filled in both chambers 4 and 6. To the fixing fitting 2 is fixed a pressing fitting 9 having a circular groove 10 at an opposite side of the chamber 4, and a partition wall 11 is movbaly installed in the groove 10. The partition wall 11 has a smaller diameter than that of the chamber 4, and held in the groove 11 by radial projected legs 11a and thereby both chambers 4 and 6 are communicated with each other through arcular pass-through holes 12.</p> |
