Abstract
A mounting structure disposed between a body and a power unit of a vehicle, including a cylindrical housing having two cavities on opposite side of a partition member, and a first and a second elastic member which close open ends of the cavities to form a first and a second variable-volume fluid chamber which are filled with an incompressible fluid. The first and second fluid chambers communicate with each other through an orifice which permits a restricted flow of the fluid therethrough. The elastic members and the orifice enable the mounting structure to damp or absorb vibrations applied thereto. The mounting structure comprises: portions defining at least one by-pass passage formed through the partition member to permit communication between the first and second fluid chambers; a rotary valve member disposed within the partition member and rotatable about its axis between its closed position in which the at least one by-pass passage is closed by the rotary valve member, and its open position in which the at least one by-pass passage is open; and a rotary actuator, responsive to an external signal, for operating the rotary valve member between the closed and open position.
