Embodiment
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in figure 4, according to rotary compressor of the present utility model, including cylinder body 40 and rotating shaft, rotating shaft is concentric shafts,
Cylinder body 40 has cylinder chamber, and cylinder chamber is with respect to rotating shaft eccentric setting, and between the internal perisporium of cylinder chamber and the periphery wall of rotating shaft
Form crescent working chamber A.The utility model is concentric shafts due to rotating shaft, by cylinder chamber with respect to rotating shaft eccentric setting, so that
Crescent working chamber is formed between the internal perisporium of cylinder chamber and the periphery wall of rotating shaft.Namely the utility model is removing rotor eccentricity
Portion, realizes and rotates compression so that pump housing operating can be relatively steady, can effectively reduce compressor noise.
Specifically, vane slot is provided with rotating shaft, slide plate 50 is slidably disposed in vane slot, is provided with vane slot
Corresponding spring 70, so that the outer end of slide plate 50 keeps fitting with the inner peripheral surface of cylinder chamber, and then crescent working chamber is divided
It is divided into suction muffler and compression chamber.
Preferably, in the utility model, because cylinder body 40 need not set vane slot, cylinder body 40 can use Q shape cylinders
Body, advantageously reduces the volume of compressor, so that compressor can be with smallerization.
Further, with reference to shown in Fig. 3 to 5, rotary compressor also includes upper flange 30 and lower flange 60, upper flange 30
Be provided with lower flange 60 with rotating shaft coordinate axis hole 31, and stationary housing 40 multiple fixing holes 32, multiple fixing holes
32 are distributed on the eccentric circumference of relative rotating shaft.Namely in the utility model, upper flange 30 and lower flange 60 and existing flange
Difference, circumference residing for multiple fixing holes 32 and flange endoporus decentraction, fixing hole 32 is corresponding with the screw hole of cylinder.
After assembling, connected between upper flange 30 and lower flange 60 and cylinder body 40 for decentraction, upper flange 30 and lower flange 60
It is connected with rotating shaft to be concentric；As shown in Figure 4, the inner round wall of cylinder body 40 cooperatively forms crescent working chamber A with rotating shaft, with prior art
In compressor with rolling rotor crescent moon working chamber unlike, this month teeth cavity shaped position during compressor operating shape position
Put holding constant.Fundamental diagram as shown in Figure 6, crescent moon working chamber is divided into suction muffler and compression chamber by slide plate 50；Air-breathing
Mouth 41 is located at rotating shaft and both sides at the minimum clearance of cylinder body 40 with exhaust outlet；Slide plate 50 rotation while along vane slot translation,
And it is in close contact under the pressure of spring 70 with the inwall of cylinder body 40.Usually, air entry 41 is arranged on cylinder body 40, exhaust outlet
It is arranged on upper flange 30.
In the utility model, rotating shaft can use integrated formed structure, i.e., set in rotating shaft and the corresponding part of cylinder body 40
