Abstract
A fluid-filled elastic mount wherein an elastic body which elastically connects an inner and an outer sleeve partially defines a pressure-receiving chamber filled with a non-compressible fluid, and an oscillating plate is provided to partially define an auxiliary fluid chamber which cooperates with the pressure-receiving chamber to form a fluid chamber. Two yoke members are connected to respective opposite pole faces of a permanent magnet disposed on one of opposite sides of the oscillating plate remote from the fluid chamber. The yoke members, which cooperate with the permanent magnet to define a closed magnetic circuit, define therebetween an annular gap in the magnetic circuit, in which is received an annular moving coil fixed to the oscillating plate. The coil is axially displaced in the gap to oscillate the oscillating plate upon energization of the coil.
