Embodiment
Below with reference to accompanying drawing and combine embodiment to specify the utility model.
Shown in Fig. 1 to 3, the variable compressor according to the utility model comprises: cylinder 10, and cylinder 10 lower end surfaces are provided with relief opening 11; Lower flange 20, lower flange 20 is fixedly installed on the lower end of cylinder 10, and lower flange 20 is provided with the vent 21 corresponding with relief opening 11; Lower flange 20 is provided with the valve block 22 of opening or closing vent 21; Valve block 22 downsides are provided with baffle plate 23, and the end away from vent 21 of baffle plate 23 is fixed on the lower flange 20, and baffle plate 23 is corresponding to having the gap between end of vent 21 and the vent 21; Baffle plate 23 is provided with the calutron 25 of control valve block 22 motions near an end of vent 21.Through on the baffle plate 23 of valve block 22 bottoms, calutron 25 being set; When valve block 22 is opened, through calutron 25 valve block 22 is adsorbed on the baffle plate 23, can guarantee that exhaust ports is in long opening state; The exhaust resistance that is produced when preventing valve block 22 frequent vibration improves the bypass effect.
Preferably, as shown in Figure 3, lower flange 20 is provided with groove, and baffle plate 23 and valve block 22 are arranged in the groove, and are fixed on the lower flange through rivet 24.Baffle plate 23 to away from the bending of vent 21 directions, makes valve block 22 that certain activity space can be arranged near an end of vent 21.
Shown in Fig. 2 and 3, calutron 25 comprises the iron core 25a that is installed on the baffle plate 23, and iron core 25a can weld perhaps through being threaded on the baffle plate 23; Be wound with coil 25b on the iron core 25a; Coil 25b is entwined by the copper cash that is surrounded by isolation layer, preferably, is entwined by enameled cable.
The distance that calutron 25 control valve blocks 22 leave vent 21 is H, wherein 2.2mm≤H≤3.6mm.When the angle of opening when valve block was big more, exhaust resistance was more little, but carried out next round when air-breathing when the pump housing, and the air-breathing backflow of valve block open place generation also can be big more; The angle of opening when valve block more hour, exhaust resistance is big more, but can reduce air-breathing backflow this moment.To sum up, and combine the variation of compressor operating volume size, the optimum valve block lift amount of design is between 2.2～3.6mm, between 16.8 °～17 ° of the corresponding valve block opening angles.
As shown in Figure 4, the bottom of lower flange 20 is provided with flange cover 27, and flange cover 27 forms closed cavity with lower flange 20, and the sidewall of flange cover 27 is provided with through hole radially, is connected with bypass tube 28 in the through hole.As shown in Figure 5, the intakeport that the other end of bypass tube 28 is connected compressor liquor separator 40 forms bypass circulation, and refrigerant is drawn compressor 30.Refrigerant is introduced the liquor separator intakeport through bypass circulation, finally reaches the bypass effect.Preferably, bypass tube 28 is provided with solenoid valve 50, the switching of control bypass tube 28, and bypass tube 28 is a copper pipe.
When refrigerant is compressed to a certain degree in compression chamber, through the vent 21 that the relief opening of cylinder lower end surface 11 arrives on the lower flanges, press off valve block 22 after; Meanwhile controller connects power supply, and when controller controling circuit was communicated with, electric current arrived among the coil 25b through lead; By electric magnetisation, hot-wire coil 25b and iron core 25a produce electromagnetic force, and magnetic force can be adsorbed on the valve block that is pressed off 22 on the baffle plate 23; Avoid the backflow that produces because of valve block 22 surgings; And then effectively improving the bypass effect, refrigerant flow in the airtight cavity of flange cover 27 and lower flange 20 formation, solenoid valve 50 unlatchings this moment; Refrigerant flow back into the intakeport place of liquor separator 40 through bypass tube 28, thereby reaches the bypass effect.
If in the time of need closing bypass, then solenoid valve 50 cuts out, controller cuts off the electric current of coil 25b, and coil 25b and iron core 25a do not produce magnetic field, and valve block can be got back to closed state.When initial, still have the part refrigerant to get in the cavity of flange cover and lower flange formation, but along with the refrigerant that gets into increases; Airtight cavity pressure inside raises, when pressure acquires a certain degree, when promptly descend the inside and outside pressure of relief opening equal; Valve block will no longer be pressed off, promptly can not bypass.
