Claim 0:
1. A compressor comprising:
a compressor main body which houses a plurality of compression mechanism units and an electric motor unit driving the plurality of compression mechanism units in a case;
an accumulator supported by the compressor main body and including a refrigerant introduction part at an upper portion thereof; and
three suction pipes penetrating a bottom portion of the accumulator, having one end sides which open inside the accumulator, and having the other end sides connected to three suction ports provided in the case, wherein
the three suction pipes are a first suction pipe, a second suction pipe, and a third suction pipe,
the three suction pipes are disposed at a portion penetrating the bottom portion of the accumulator so that a first center of a first flow path cross section of the first suction pipe, a second center of a second flow path cross section of the second suction pipe, and a third center of a third flow path cross section of the third suction pipe are positioned at vertices of a triangle with all three angles acute as viewed from above the accumulator,
the first suction pipe is disposed so that a first distance between the first center and a center of the compressor main body is smaller than a second distance between the second center and the center of the compressor main body and a third distance between the third center and the center of the compressor main body,
the other end side of the first suction pipe is connected to a first suction port which is positioned uppermost among the three suction ports,
the three suction pipes include main curved pipe parts which are curved from below the accumulator toward the three suction ports,
a second virtual plane on which a central axis of the main curved pipe part of the second suction pipe is disposed and a third virtual plane on which a central axis of the triam curved pipe part of the third suction pipe is disposed are inclined to opposite sides from each other with respect to a first virtual plane on which a central axis of the main curved pipe part of the first suction pipe is disposed,
the other end side of the third suction pipe is connected to a third suction port which is positioned lowermost among the three suction ports,
θ2<θ3 is established when an inclination angle of the second virtual plane with respect to the first virtual plane is θ2 and an inclination angle of the third virtual plane with respect to the first virtual plane is θ3, and
a center of the accumulator is located on the first virtual plane, and inside the triangle whose vertices are the first center, the second center, and the third center on the bottom surface of the accumulator.
