Here first it should be noted that, in description of the invention: " inside and outside " direction is the position based on compression chamber 11, the direction of contiguous compression chamber 11 is " introversion ", is " extroversion " away from the direction of compression chamber 11.
As shown in Figure 2, the diameter D of outer section 131 of suction port 13 is greater than the diameter d of Inner section 132, and the axis Z1 of outer section 131 of suction port 13 does not overlap with the axis Z2 of Inner section 132.Because the diameter D of outer section 131 is greater than the diameter d of Inner section 132, can make like this gas entering from suction port 13 flow into more swimmingly in compression chamber 11, can make thus the inhalation resistance loss of suction port 13 reduce.For the volumetric efficiency of the compression chamber 11 that makes cylinder 10 is improved, can reduce between suction port 13 and vane slot 12 in week distance upwards, thereby can increase the volume of effective compression volume of compression chamber 11, and then can make the volumetric efficiency of the compression chamber 11 of cylinder 10 be improved, therefore, reduce the diameter d of Inner section 132, and the axis Z2 that makes Inner section 132 and the axis Z1 of outer section 131 setting that do not overlap, thereby can avoid the structures such as suction port 13 and vane slot 12 around, screw hole, positioning hole to interfere.Can make thus rotary compressor 100 more efficient, energy-conservation.
Wherein, outer section 131 and the diameter of Inner section 132 of suction port 13, under the prerequisite not interfering in structures such as guaranteeing suction port 13 and the vane slot 12 around it, screw hole, positioning hole, can be designed into large as far as possible, the direction that simultaneously position of outer section 131 and Inner section 132 can be close to vane slot 12 as far as possible.
