    Abstract: A defroster restrains a vane jump that takes place when an evaporator is defrosted in a refrigerant circuit using a so-called internal intermediate-pressure type double-stage compression rotary compressor (10). The defroster includes a rotary compressor (10) that discharges a refrigerant gas that has been compressed by a first rotary compressing unit (32) into a hermetic vessel (12) and further compresses the discharged intermediate-pressure refrigerant gas, a gas cooler (154), an expansion valve (156), and an evaporator (157). To defrost the evaporator (157), the refrigerant gas discharged from the second rotary compressing unit (34) is introduced into the evaporator (157) without decompressing it by the expansion valve (156). Furthermore, the refrigerant gas discharged from the first rotary compressing unit (32) is introduced into the evaporator (157). At the same time, an electromotive unit (14) of the rotary compressor (10) is run at a predetermined number of revolutions. The inertial force of a vane (50) at the foregoing number of revolutions is set to be smaller than the urging force of a spring (76).

    Abstract: A multi-stage compression type rotary compressor is provided to prevent an exhaust valve of a second rotary compression element from being broken due to a pressure between stepped portions in a second stage. A multi-stage compression type rotary compressor(10) comprises a driving unit(14) in a sealing container(12), and first and second rotary compression elements(32,34) driven by the driving unit. Refrigerant gas of a medium pressure compressed by the first rotary compression element is exhausted to the second rotary compression element. A communicating passage(100) communicates a passage of the refrigerant gas compressed by the first rotary compression element with a refrigerant exhaust side of the second rotary compression element. The communicating passage is opened and closed by a valve device. If a pressure difference between the refrigerant gas of a medium pressure and refrigerant gas of the refrigerant exhaust side of the second rotary compression element exceeds a predetermined maximum limit, the valve device opens the communicating passage.

    Abstract: A method for manufacturing a multi-stage compression type rotary compressor is provided to simplify the structure of a vane for dividing a cylinder into a low pressure chamber and a high pressure chamber. A method for manufacturing a multi-stage compression type rotary compressor(10) comprises a step of exhausting refrigerant gas compressed by a first rotary compression element(32) to a second rotary compression element(34). The first and second rotary compression elements are driven by a driving unit(14) in a sealing container(12). The first and second rotary compression elements include first and second cylinders(38,40), and first and second rollers(46,48), respectively. The first and second rollers are inserted into first and second eccentric units(42,44) formed at a rotating shaft(16) of the driving unit. An inner diameter of a corresponding cylinder is changed without varying a thickness of the first cylinder, so that a displacement volume ratio of the first and second rotary compression elements is set.
