Abstract
A compressor includes a casing, a compression mechanism, and a refrigerant introduction tube. The casing includes a cylindrical portion surrounding an axis line. The compression mechanism includes a compression chamber. The compression mechanism is welded to the cylindrical portion at a first welding point. The refrigerant introduction tube is configured to guide a refrigerant to the compression chamber. The refrigerant introduction tube overlaps with the first welding point in a plan view seen along a direction in which the axis line extends.
Claims13
A compressor comprising:
- a casing including a cylindrical portion surrounding an axis line;
- a compression mechanism including a compression chamber, the compression mechanism being welded to the cylindrical portion at a first welding point;
- a suction tube configured to guide refrigerant having a low pressure to the compression chamber;
- a discharge tube configured to guide refrigerant having a high pressure to outside the casing;
- and
- an injection tube configured to guide refrigerant having an intermediate pressure to the compression chamber, the intermediate pressure being between the low pressure and the high pressure, and the injection tube overlapping with the first welding point in a plan view seen along a direction in which the axis line extends,
- the injection tube extending along a line segment connecting the axis line and the first welding point.
