Abstract
A rotary compressor includes: a compressor body including an airtight container that has a refrigerant intake opening and a refrigerant discharge opening, a refrigerant compression unit that has a cylinder and a rotary piston housed in the cylinder and that is provided in the airtight container, and an electric motor that drives the rotary piston and is provided in the airtight container; and an accumulator configured to separate a refrigerant suctioned into the refrigerant intake opening into gas and liquid. The accumulator and the refrigerant intake opening are connected via a refrigerant intake pipe, a suction opening of the refrigerant intake pipe is arranged to be opened to the inside of the accumulator, an injection pipe for pouring the refrigerant into the rotary compressor is inserted into the accumulator from above, and a discharge opening of the injection pipe is drawn to face the suction opening of the refrigerant intake pipe in a refrigerant gas space of the accumulator.
