Patent attributes
A two-stage rotary compressor includes a sealed cylindrical compressor housing that includes first, second and third communication holes separately arranged sequentially in an axial direction on an outer peripheral wall, an accumulator held on an outer side of the housing, a low-pressure connecting pipe that connects a bottom communication hole of the accumulator and the second communication hole, and an intermediate connecting pipe that connects the first and third communication holes. The second and third communication holes are arranged at nearly the same circumferential direction position of the housing. The accumulator is held at nearly the same circumferential direction position as the second communication hole. The first communication hole is arranged at a circumferential direction position different from the second and third communication holes to ensure that the low-pressure connecting pipe and the intermediate connecting pipe two dimensionally bent in a circular arc shape do not interfere with each other.
