Claims

[Claims for Utility Model Registration] (1) An electric element is housed in the upper part of the airtight container, and a compression element driven by its vertical axis is housed in the lower part. 2, which is taken out laterally from each of the upper and lower cylinders, bent upward, and opened upward into the suction accumulator, to connect the inside of each of these cylinders and the inside of the suction accumulator disposed adjacent to the closed container. 1. A two-cylinder rotary compressor that is connected to each other independently by two suction pipes, characterized in that the two suction pipes have approximately the same line resistance. (2) A two-cylinder rotary compressor according to claim 1, in which the two suction pipes have substantially the same resistance by making the opening ends of the two suction pipes have different vertical positions. (3) A two-cylinder rotary compressor according to claim 1 or 2, in which the two suction pipes have different bending radii so that the pipe line resistance is substantially the same. (4) A two-cylinder rotary compressor according to claim 1, in which the two suction pipes have different inner diameters and lengths so that the line resistance is approximately equal. (5) The suction pipe connected to the inner lower cylinder of the above two suction pipes has a larger inner diameter and longer length than the suction pipe connected to the upper cylinder, so that both suction pipes in the above suction accumulator are A two-cylinder rotary compressor according to claim 4, characterized in that the vertical positions of the opening ends of the suction pipes are approximately equal.
