Abstract (en)
[origin: EP2530324A2] According to one embodiment, a rotary compressor sucks in refrigerant gas from the low pressure side of a refrigeration cycle and discharges compressed refrigerant gas to the high pressure side. The rotary compressor includes a first compressing unit (12S) and a second compressing unit (12T) arranged one on top of another with a partition board (140) therebetween. The partition board (140) is provided with a vertical hole (141) and a horizontal hole (143). After the front end (144a) of an injection copper tube (144) to inject a refrigerant liquid is loose fit in the horizontal hole (143), an injection liner (145) having an outer diameter larger than the inner diameter of the injection copper tube (144) is inserted into the injection copper tube (144) from the back end (144b) and is pressed up to the front end (144a) to increase the diameter of the front end (144a) of the injection copper tube (144) such that the injection copper tube (144) is tight fit in the horizontal hole (143).
