PROBLEM TO BE SOLVED: To solve the problem that high pressure refrigerant gas returns to a compression chamber side again and causes performance drop due to re-compression since compressed refrigerant gas remains in a space after completion of compression although a chamfered shape of the compression chamber side of a cylinder inner diameter is formed large to reach a discharge port for preventing liquid compression operation and communication between the discharge port and the space surrounded by a blade, a cylinder and a roller is provided in a rotary compressor of a conventional structure. SOLUTION: The chamfer shape of the compression chamber side of the cylinder inner diameter is formed smaller than of the rotary compressor of the conventional structure and a notch section is provided between the chamfer shape and the discharger port. Consequently, performances of the compressor are improved by reducing re-compression volume while preventing liquid compression operation. COPYRIGHT: (C)2011,JPO&INPIT
