摘要:
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.

A copper alloy includes Si to facilitate deoxidation, and can be easily manufactured even when including elements such as Cr or Sn. The copper alloy has high conductivity and high workability without negatively affecting the tensile strength. The copper alloy contains 0.2 to 0.4 wt % of Cr, 0.05 to 0.15 wt % of Sn, 0.05 to 0.15 wt % of Zn, 0.01 to 0.30 wt % of Mg, 0.03 to 0.07 wt % of Si, with the remainder being Cu and inevitable impurities. A method for manufacturing the copper alloy includes obtaining a molten metal having the described composition; obtaining an ingot; heating the ingot at a temperature of 900-1000° C. to perform a hot rolling process; cold rolling; performing a first aging process at a temperature of 400-500° C. for 2 to 8 hours; cold rolling; and performing a second aging process at a temperature of 370-450° C. for 2 to 8 hours.
