Piston 320 is combined together with container 310, then (does not show the upper end of piston rod 330 in figure through the through hole in mounting seat 40
Go out), screwed and be connected with the external screw thread on piston rod 330 using nut, thus foot pad 30 is fixed in mounting seat 40.
As Figure 1-Figure 2, upwardly recessed consolidate is provided with according to some embodiments of the present invention, the exterior bottom wall of container 310
Determine space 3110, the internal perisporium of fixed space 3110 is provided with matching thread, so as to facilitate foot pad 30 and the metal plate on air conditioner
The assembling of golden part.In the specific example of the present invention, the fixed space 3110 in the exterior bottom wall of container 310 is formed as cylinder
Hole, the internal perisporium of fixed space 3110 are provided with internal thread, when the sheet metal component on foot pad 30 and air conditioner assembles, on sheet metal component
Threaded post screw and be connected with fixed space 3110.
Air conditioner according to embodiments of the present invention, including compressor according to the above embodiment of the present invention 100.
Air conditioner according to embodiments of the present invention, by setting above-mentioned compressor 100, compressor 100 is provided with damping group
Part 20 and multiple foots pad 30, vibration can be transferred to by housing 10 when compressor 100 works, caused by compressor 100 subtracts
Component 20 is shaken, flexible component 240 can reduce the vibratory output being transferred on damping chamber 230 to vibrating into row buffering.Damping chamber
Multiple metallic particles 220 in 230 are in the presence of vibration, between the inwall of metallic particles 220 and damping chamber 230 and metal
Constantly it can be collided and be rubbed between particle 220 and metallic particles 220.Phase between metallic particles 220 and metallic particles 220
Mutually collision can balance out partial vibration kinetic energy, and the friction between metallic particles 220 and metallic particles 220 can change into heat
Can, heat discharges compressor 100 by damping shell 210, so as to play the effect of damping.Further, compressor 100 produces
Raw vibration forms downward dynamic impact loading on foot pad 30, and the stress of elastomer 340 in liquid 350 is simultaneously carried out
Shrink, by the Momentum absorption of vibration and change into heat, heat is spread out of by the side wall of container 310, so as to play damping
Effect, can prevent that vibration is transferred on sheet metal component caused by compressor 100, it is possible thereby to reduce the work of compressor 100
Noise.Compressor 100 can play good damping effect, most by way of dampening assembly 20 and multiple foots pad 30 combine
The work noise of the reduction compressor 100 of limits.
