Shown in Fig. 2, Fig. 3 and Fig. 4, described the second flange 7 has center hole 75 and the pilot hole 71 for holding pin 10 be connected with bent axle, be provided with oil groove 75a on the inwall of this center hole 75, in this pilot hole 71, being equipped with can axially movable pin 10, the head of this pin 10 can insert in described lock groove 91, with by the second vane slot 63 lockings, the afterbody of this pin 10 is equipped with elastic reset member (being preferably spring 11).Preferably, the center line eccentric setting of the center line of described lock groove 91 and described pin 10, can guarantee that like this second slide plate 9 and roller break away from fully, pin 10 is when locked the second slide plate 9 simultaneously, the top of pin 10 does not contact with the bottom of lock groove 91, guarantee that enough mineralization pressure chambeies, space are arranged at the top of pin 10 when needs pin 10 breaks away from lock groove 91.
Pressure difference mechanism is for producing pressure difference between the head at described pin 10 and afterbody.Utilize like this pressure reduction of pin 10 heads and afterbody to make pin 10 fore and aft motion in pin 10 holes, with locking optionally or unclamp the second slide plate.For fear of the Leakage Gas in the gap (the A place in Fig. 2) between pin 10 and pin 10 holes and the gap (the B place in Fig. 2) between pin 10 afterbodys and lower cover plate 8, be provided with the first oil supply gallery 73a that is communicated with described pilot hole 71 and described oil groove 75a on second flange 7 of the present embodiment.Preferably, for convenient processing, described the first oil supply gallery 73a comprises the second oil circuit 73b radially that arrange and the first oil circuit 73a that be communicated with described oil groove 75a and this first oil circuit 73a of connection and described pilot hole 71.Further preferably, described the second oil circuit 73b is the groove (be preferably rectangle groove) of opening towards described second level cylinder 6.In addition, the second oil supply gallery 74 that is communicated with described pilot hole 71 and described housing 1 inner chamber also can be set on the second flange 7.Preferably, described the second oil supply gallery 74 extends to the side of opposite side in the face of the side axial of described second level cylinder 6 from described the second flange 7.In the situation that pasta falls is not very low, refrigeration oil just can enter two gap locations by the second oil supply gallery 74, thereby reaches oil sealing like this.
The pressure difference mechanism of the present embodiment comprises the enclosed cavity 64 that is arranged on described the second vane slot 63 afterbodys and be communicated with described lock groove 91 and described housing 1 inner chamber, be arranged on described pin 10 back to the pressure chamber of its head one side, be communicated with this pressure chamber and described the second intakeport 61 be connected air flue and pressure switching device 13, described the second intakeport 61 is communicated with the relief opening of described liquor separator 12 and the inner chamber of described housing 1 by described pressure switching device 13 selectivity.Preferably, pressure switching device 13 is three-way valve, a port of pressure switching device 13 is connected with another relief opening of liquor separator 12, and second port of pressure switching device 13 is connected with the second intakeport 61, and the 3rd port of pressure switching device 13 is connected with outlet pipe 1a.When the second intakeport 61 is communicated with the relief opening of liquor separator 12, the afterbody of pin 10 is low pressure, poor with the head mineralization pressure of pin 10, and now, pin 10 and the second slide plate 9 unclamp, the operation of compressor twin-stage; When the second intakeport 61 is communicated with outlet pipe 1a, the afterbody of pin 10 is high pressure, with the head of pin 10, there is no pressure difference, and now, pin 10 is by the second slide plate 9 lockings under the effect of spring 11, and the compressor single-stage is moved.
Pressure difference mechanism, except the structure that adopts the present embodiment, can also adopt other structures, and as the formerly patent application mentioned in background technique, (application number: the structure adopted 201220232315.5) does not repeat them here.
Preferably, the afterbody at described pin 10 is provided with for placing the first spring eye 10a of spring 11.Be provided with second spring eye 81 corresponding with the first spring eye 10a on lower cover plate 8, the lower end of spring 11 is placed in the second spring eye 81.Described pilot hole 71 and described the second spring eye 81 mineralization pressure chambeies by described pin 10 belows, pressure chamber is connected with described intakeport through connecting air flue, connect air flue and be used for transmission of pressure, the gas that there is uniform pressure in pin 10 afterbodys and the second intakeport 61 like this.Preferably, described connection air flue comprises and is arranged on the first attachment hole 62 on described second level cylinder 6 and that be connected with described the second intakeport 61, is arranged on the second attachment hole 72 on described the second flange 7 and that be connected with described the first attachment hole 62, is arranged on the 3rd attachment hole 82 on described lower cover plate 8 and that be connected with described the second attachment hole 72 and is arranged on the 4th attachment hole 83 of described the 3rd attachment hole 82 of connection on described lower cover plate 8 and described the second spring eye 81.
Below further the working principle of the embodiment of the present invention is carried out to brief description:
1. twin-tub operation
The pressure that refrigerant enters the first intakeport 41 and the second intakeport 61, the first intakepories 41 and the second intakeport 61 places by liquor separator 12 is low pressure.Want while moving due to twin-tub that depended on pressure is poor depresses pin 10, admittedly while starting shooting owing to not forming needed pressure reduction, the second slide plate 9 also is in lockup state, now the state of compressor in the single cylinder operation.After operation a period of time, the pressure in housing 1 raises, and now the second intakeport 61 places are low pressure, and under the effect of pressure difference, pin 10 moves down so, and the locking of the second slide plate 9 is disengaged, resume operation, and the operation of compressor twin-tub.
The two-stage variable-capacity compressor of the embodiment of the present invention, due to the oil supply gallery be provided with on the second flange 7 for the gap fuel feeding between pin 10 and pilot hole 71, can guarantee to have refrigeration oil between pin 10 and pin 10 holes always, make compressor can realize the smooth switching of single twin-tub, guarantee that the performance of compressor can not degenerate simultaneously.
2. single cylinder operation
Refrigerant is divided into two-way by liquor separator 12, one tunnel directly enters the first intakeport 41, one tunnel is blocked through pressure switching device 13, now the pressurized gas of outlet pipe 1a enter the second intakeport 61 through pressure switching device 13, the second intakeport 61 places are high pressure, and pin 10 afterbodys communicate with the second intakeport 61 by connecting air flue.Gu pin 10 afterbodys are also high pressure, and suitable with the pressure of housing 1, pin 10 moves up under the effect of Returnning spring 11, locking the second slide plate 9, the running of compressor single cylinder.
In another embodiment of the present invention, provide a kind of air conditioner with above-mentioned two-stage variable-capacity compressor.
The above embodiment has only expressed several mode of execution of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
