Lotus is acted on foot pad 30, and the stress of elastomer 340 in liquid 350 is simultaneously shunk, and by the Momentum absorption of vibration and is changed into
Heat, heat are spread out of by the side wall of container 310, so as to play the effect of damping, can prevented caused by compressor 100
Vibration is transferred on sheet metal component, it is possible thereby to reduce the work noise of compressor 100.Compressor 100 passes through the He of dampening assembly 20
The mode of multiple combined shock absorptions of foot pad 30, can play good damping effect, reduce the work of compressor 100 to greatest extent
Noise.
