Abstract
A liquid-sealed vibration insulator is comprised of a cylindrical elastic member integrally formed with an inner cylinder, first and second rings and an orifice ring located between the first and second rings. An outer cylinder is integrally connected to the elastic member through the first and second rings. A first liquid chamber is formed at a portion between the outer cylinder and the elastic member and between the first ring and the orifice ring, and a second liquid chamber is formed at a portion between the outer cylinder and the elastic member and between the orifice ring and the second ring. The first and second liquid chambers are fluidly communicated through an orifice passage defined by the orifice ring.
