Axis is not arranged on the same straight line, and is connected by the horizontally disposed groove 402 on compressor pump, so that silencers channel
40 form bending structure, and bending part of the sound wave in silencers channel 40 can be made to reflect, increase sound wave in silencers channel
Order of reflection in 40 changes the propagation characteristic of sound wave, increases the energy loss of air-flow, to reduce pneumatic noise.
It is understood that at least one of the first air duct 404, the second air duct 406, third air duct 408 and groove 402
The angle with predetermined angle α is formed between horizontal plane, wherein 0 ° of 180 ° of ＜ α ＜, selectable value is 30 °, 60 ° or 120 °, from
And order of reflection of the sound wave in silencers channel 40 can be further increased, ensure erasure effect.
Technical scheme of the present invention is described in detail above in association with attached drawing, the present invention provides a kind of compressor pump and rotations
Rotary compressor, using the groove 402 being formed on upper bearing (metal) 20, cylinder 10 and lower bearing 30, to increase on compressor pump
Noise-reducing structure divergence ratio and length, to make compressor pump have bigger sound-damping qualities and broader noise reduction frequency model
It encloses, improves the noise reduction of noise-reducing structure；The length that silencers channel 40 can also be extended according to actual needs simultaneously, to meet
The application scenarios of different noise reduction demands；In addition, the problems such as capable of eliminating main parts size height dimension and Assembly Interference, is to expansion
The influence of Theoretical Design length is unable to reach than doing little or expansion cavity length so that compressor pump has more noise reductions
Measure and expand noise reduction frequency range.
