Document Type and Number:
Japanese Patent JP2012021466
Kind Code:
A
Abstract:
To provide a rotary compressor equipped with the dug part for improving the compressor efficiency by the volume reduction of a discharge opening arranged in a cylinder or a closing member, wherein the formation of the dug part is prevented, efficiency and reliability of the compressor are enhanced, the force of a spring generated in an arm part of the discharge valve closing the discharge opening is reduced, and the efficiency of the compressor is enhanced.
