Abstract: An air-damping mount, in which a displaceable bellows plate is mounted in order to define a damping chamber. A rigid or displaceable partition plate having at least a through-hole is mounted in the damping chamber, and thereby partitions the damping chamber into an upper chamber and a lower chamber. At least an orifice tube is mounted on and connected with the through-hole so as to allow the upper and lower chambers to fluidly communicate with each other. Thereby, the air-damping engine mount can reduce engine vibration by means of flow resistance of air occurring when the air passes through the through-hole and the orifice tube and by means of displacement of the displaceable bellows plate caused by a change in pressure of the lower chamber, and thus remarkably improve a damping effect of the engine vibration.
