Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can be mutually combined.
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Embodiment one：
As shown in Figs. 4-6, the cylinder of the rotor-type compressor of the present embodiment includes vane slot 1, exhaust outlet 2 and air discharge duct 3.
Vane slot 1 is arranged on the internal perisporium of cylinder；Exhaust outlet 2 is arranged on the internal perisporium of cylinder, and positioned at the side of vane slot 1；
Air discharge duct 3 is arranged on the internal perisporium of cylinder, and extends to vane slot 1 by exhaust outlet 2.
In the present embodiment, the roller of compressor after exhaust outlet 2 is turned over, then to vane slot 1 direction rotate when formed press again
Refrigerant in contracting space is guided to exhaust outlet 2 through air discharge duct 3 discharges, it is to avoid gas being vented the presence of enclosed volume because producing again
Second compression.Therefore, the refrigerant in recompression space advantageously accounted for low-pressure side leak the problem of.
Exhaust outlet 2 is arranged on axial one end of cylinder.Exhaust outlet 2 is the groove for the upper edge for being arranged on cylinder, for by gas
The refrigerant discharge of compression in cylinder.
In the present embodiment, the second end of air discharge duct 3 is located at the position close to one end for being provided with exhaust outlet 2 of cylinder.It can subtract
The length of few air discharge duct 3, reduces processing capacity, is conducive to improving processing efficiency.
Alternatively, the first end of air discharge duct 3 is connected with exhaust outlet 2, and the second end of air discharge duct 3 is located at the axial middle part of cylinder.
So that the above-mentioned axial direction in compression stroke smoothly can be discharged through air discharge duct 3 everywhere.
In the present embodiment, the second end of air discharge duct 3 is connected with vane slot 1.Air discharge duct 3 is extended and communicated as vane slot 1,
Avoid remaining refrigerant in above-mentioned recompression space.
In the present embodiment, air discharge duct 3 is curved.In exhaust outlet 2 to vane slot 1 between the two limited distance, increase row
The development length of air drain 3, in favor of collecting the refrigerant in above-mentioned recompression space, and is discharged it.
The air discharge duct 3 come is cut in cylinder inner peripheral surface can be processed as arc, and deep-slotted chip breaker size is the smaller the better, such as Fig. 4 to 6
It is shown.The enclosed volume for constituting above-mentioned recompression space is communicated with exhaust outlet 2, eliminates the adverse effect of exhaust enclosed volume,
Avoid gas to compress once again, reduce power, while reducing from slide plate both ends of the surface or the high pressure chest of R faces generation to low pressure chamber
Amount of leakage.
The enclosed volume that the leading edge angle of exhaust outlet 2 is constituted is turned on steam vent, and the gas in enclosed volume is discharged in time,
Avoid gas to compress once again, reduce compressor power consumption.
Implementation is as follows：A groove is cut in the leading edge angle Φ inside cylinder inner circles of exhaust outlet 2, to constitute air discharge duct 3,
Enclosed volume is turned on exhaust outlet 2, gas has both been can be avoided and has compressed once again, compressor power consumption is reduced, substantially reduces simultaneously
Pressure in enclosed volume is vented, exhaust enclosed volume and the pressure difference of low-pressure side are reduced, so as to reduce by slide plate both ends of the surface or R
The high pressure chest that face is produced is to low pressure chamber amount of leakage.
By the program, compressor horsepower can be not only reduced, while reducing compressor leakage coefficient, compressor efficiency is improved.
