Claims

[Scope of utility model registration request]

If at least a part of the suction pipe connecting the compressor and the accumulator is made up of multiple pipes, and each pipe has a different length and/or diameter, an on-off valve may be inserted in the middle of each pipe to improve compression. A rotary compressor, characterized in that the on-off valve is selectively opened and closed according to operating conditions of the machine.
