ABSTRACT:
In a two-cylinder type hermetic rotary compressor, a first cylinder continually operates due to a spring member biasing a first vane. A pressure introducing pipe is connected to a second vane room arranged in a second cylinder. The second cylinder stops and starts operation by introducing sucking pressure or discharge pressure from the pressure introducing pipe. A discharge pressure introducing pipe that is connected to a portion of a hermetic case below the oil face of the lubricating oil is connected to the pressure introducing pipe.
