Abstract: A hermetic rotary compressor operates two cylinders simultaneously in the regular operation; however it halts operating one of the cylinders when it selects an operation with a half capacity. A vane room of the halted cylinder is air-tightly sealed with respect to lubricant atmosphere in a hermetic case. An oil-supplying groove is provided to a vane groove of the halted cylinder, and lubricant is supplied to the oil-supplying groove in order to lubricate the vane.

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.

Abstract: In a two-cylinder type hermetic rotary compressor, a first cylinder is always compressed and operated since a spring member biases a first vane. A pressure introducing pipe is connected to a second vane room arranged in a second cylinder. The second cylinder is stopped in operation and is operated by introducing sucking pressure or discharge pressure from the pressure introducing pipe. A discharge pressure introducing pipe connected to a portion of a hermetic case below the oil face of lubricating oil is connected to the pressure introducing pipe.

Abstract: A hermetic compressor comprises a hermetic container, an electric motor and a compressing mechanism installed inside of the hermetic container, lubricating oil and refrigerant gas enclosed within the hermetic container, a first temperature detector disposed to a predetermined location within the hermetic container, and a second temperature detector disposed to a location adjacent to a surface of the lubricating oil in the hermetic container. The predetermined location where the first temperature detector is disposed is one of a location near an upper end and another location near a lower end within a space inside the hermetic container, and an amount of the lubricating oil in the hermetic container is determined according to temperatures detected by the first temperature detector and the second temperature detector.
