US Patent 7748968 Two-cylinder rotary compressor with suction pipes

In a two-cylinder rotary compressor, two compressing sections accommodated in a compressor body and an accumulator are connected to each other by two suction pipes each formed with an L-shaped bend part in the intermediate pipe part thereof. To reduce a pressure loss caused by the flow resistance of a refrigerant sucked from the accumulator into the compressor, the L-shaped bend parts of the two suction pipes are arranged on different imaginary planes including the center axis line of the compressor body.
