In oil pocket 30, the relatively low lubricating oil of temperature can be to cold in the first cylinder or the second cylinder by heat transfer in Oil Guide chamber 30
Matchmaker is cooled down, and so as to reduce the temperature of refrigerant, improves the efficiency of compressor.
Specifically, Oil Guide chamber 30 is arranged on the suction hole of close first cylinder of body 10 and/or close to the second cylinder
The position of suction hole.Cylinder produces suction superheat in the suction muffler of the position of suction hole and close suction hole at work
Problem.By the way that Oil Guide chamber 30 to be arranged on to the suction hole close to the first cylinder of body 10 or the suction hole close to second cylinder
Position, suction superheat can be prevented by the cooling effect of lubricating oil.The temperature of refrigerant can be so reduced, so as to improve compression
The volumetric efficiency and efficiency of machine.Oil Guide chamber 30 is set at the same time close to the suction hole of the first cylinder and the suction hole of the second cylinder
Position, two cylinder suction superheats can be prevented simultaneously.
As shown in figure 1, Oil Guide chamber 30 is sector structure.Oil Guide chamber 30 is arranged to sector structure, Oil Guide chamber can be increased
30 volume, so that the more lubricating oil of the memory storage of Oil Guide chamber 30, and can match with the shape of the intake region of cylinder,
So as to improve the cooling effect to refrigerant.Lubricating oil in the present embodiment can be understood as the refrigeration oil in compressor.
In the present embodiment, the angle between two end faces of sector structure can be arranged to 180 ° to 220 °, with the air-breathing with cylinder
Region matches.
