Described bloop is arranged on the exhaust port and is communicated with exhaust port.
Described wrap is positioned at the inner end that is at disk body center, and the other end is the outer end, and bloop is arranged at the tooth bottom of wrap inner end, and is communicated with through air vent and the pressing chamber that is arranged on the wrap.
Described bloop is one or more.
Described exhaust port is a step hole, comprises upper air-vent and following exhaust port, and described bloop is arranged on the upper air-vent step or is arranged at down on the exhaust port step.
Described air vent is for being communicated with bloop and the gas guide groove of center pressing chamber or the groove of cutting sth. askew.
The advantage of the utility model:
(1), the part refrigerant gas gets into bloop and behind the baffling of hole, flows out then, mixes minimizing gas, thereby the noise level of reduction compressor with refrigerant gas through exhaust port;
(2), bloop is arranged at the tooth bottom of exhaust port place or the wrap inner end of price fixing, can not influence the minimum cylinder volume efficient of compressor, and fabricating cost is low, easy to process.

Embodiment
See Fig. 1, a kind of scroll compressor, include housing 12, be arranged at rotating shaft 13 in the housing 12, be connected in rotating shaft 13 tops moving scroll 14 and with moving scroll engagement decide scroll 15;
See Fig. 2, Fig. 3; Decide scroll 15 and comprise disk body 1, the bottom of disk body 1 is provided with wrap 2, and its top is provided with the exhaust port of stepped shape; Exhaust port comprises upper air-vent 3 and following exhaust port 4; Space in the wrap is a pressing chamber 5, and pressing chamber 5 is interconnected with following exhaust port 4, and the step position that is positioned at exhaust port on the disk body is provided with the bloop 6 that is communicated with upper air-vent 3.
See Fig. 1, a kind of scroll compressor, include housing 12, be arranged at rotating shaft 13 in the housing 12, be connected in rotating shaft 13 tops moving scroll 14 and with moving scroll engagement decide scroll 15; See Fig. 4, Fig. 5; Decide scroll 15 and comprise disk body 1, the bottom of disk body 1 is provided with wrap 2, and its top is provided with the exhaust port of stepped shape; Exhaust port comprises upper air-vent 3 and following exhaust port 4; Space in the wrap is a pressing chamber 5, and pressing chamber 5 is interconnected with following exhaust port 4, and bloop 6 is arranged at the step position that is positioned at exhaust port on the disk body and is communicated with following exhaust port 4.
See Fig. 1, a kind of scroll compressor that has bloop, include housing 12, be arranged at rotating shaft 13 in the housing 12, be connected in rotating shaft 13 tops moving scroll 14 and with moving scroll engagement decide scroll 15; See Fig. 6, Fig. 8; Decide scroll 15 and comprise disk body 1, the bottom of disk body 1 is provided with wrap 2, and its top is provided with the exhaust port of stepped shape; Exhaust port comprises upper air-vent 3 and following exhaust port 4; Space in the wrap is a pressing chamber 5, and pressing chamber 5 is interconnected with following exhaust port 4, its bloop 6 be arranged at wrap 2 the inner end and pass through air vent 7 and be communicated with (see figure 7) with pressing chamber 5; Wrap 2 inner ends are made up of the positive circular arc of three shed repairs: first revises circular arc 9, second revises circular arc 10 and the 3rd correction circular arc 11 (see figure 9)s, and wherein the second correction circular arc 10 is not participated in compression, so bloop 6 can not influence the volumetric efficiency of compressor.
See Fig. 1, a kind of scroll compressor that has bloop, include housing 12, be arranged at rotating shaft 13 in the housing 12, be connected in rotating shaft 13 tops moving scroll 14 and with moving scroll engagement decide scroll 15; See Figure 10, a kind of scroll compressor comprises disk body 1 with deciding scroll; The bottom of disk body 1 is provided with wrap 2; Its top is provided with the exhaust port of stepped shape, and exhaust port comprises upper air-vent 3 and following exhaust port 4, and the space in the wrap is a pressing chamber 5; Pressing chamber 5 is interconnected with following exhaust port 4; Bloop 6 is arranged at the bottom of the inner end of wrap 2, and is communicated with (seeing Figure 11) through the groove 8 of cutting sth. askew with pressing chamber 5, and wrap 2 inner ends are made up of the positive circular arc of three shed repairs: first revises circular arc 9, second revises circular arc and the 3rd correction circular arc 11 (with the said part of Fig. 9); Wherein the second correction circular arc 10 is not participated in compression, so bloop 6 can not influence the volumetric efficiency of compressor.
Refrigerant gas is discharged compression chamber by exhaust port after compression is accomplished; Because the exhaust flow velocity is higher and exist gas will produce pneumatic noise at the exhaust port place; Influence the auditory effect of compressor and air-conditioning system; The frequency range that noise distributes be can test out through the noise testing apparatus, the aperture and the degree of depth offered according to what this frequency range was accurately decided bloop 6.Discharge portion gets into bloop 6 and behind the baffling of hole, flows out the noise that mixes counteracting needs elimination frequency range with the refrigerant gas through exhaust port then, thereby the noise that reduces compressor is equivalent.
