Abstract
A fluid-filled cylindrical elastic mount having an elastic body interposed between inner and outer sleeves and cooperating with the outer sleeve to define two fluid chambers which communicate with each other through two orifice passages. An orifice-defining structure is interposed between the outer sleeve and the elastic body, so as to cover at least one of the two chambers, and has a circumferential recess open in the radially outward direction of the outer sleeve. The orifice-defining structure has two windows formed therethrough in the radial direction, and a rubber filler in the recess. The filler has two grooves one of which cooperates with one of the windows and the outer sleeve to define a first orifice passage for communication between the two chambers, and the other of which cooperates with the outer sleeve to define a second orifice passage which permits flow of a fluid between the two chambers, through elastic displacement of a flexible diaphragm which closes the other window. The two orifice passages are tuned to damp or isolate vibrations in different frequency bands.
