摘要： An internal intermediate pressure type two-stage compression rotary compressor (10) is provided with an electrically driven element (14) disposed within a sealed vessel (12), and first and second rotary compression elements (32, 34) driven by the electrically driven element (14), and is structured such as to discharge CO2 refrigerant gas compressed at a first stage by the first rotary compression element (32) within the sealed vessel (12) and compress the discharged refrigerant gas having an intermediate pressure at a second stage by the second rotary compression element (34) via an accumulator (106). The rotary compression elements (32, 34) include upper and lower cylinders (38, 40), upper and lower rollers (46, 48) eccentrically rotating within the cylinder and upper and lower vanes (50, 52) brought into contact with the rollers so as to section the inner portions of the upper and lower cylinders into high pressure chambers and low pressure chambers. A ratio of volume between the upper and lower cylinders (38, 40) executing the compression operation at the first stage and the second stage is set to 1:0.65 so that an equilibrium pressure becomes equal to an intermediate pressure. Since a pressure change at a time of starting is reduced, an oil foaming is restricted and it, is possible to easily employ a withstand pressure design of a sealed vessel, it is possible to easily design a withstand pressure vessel and it is possible to reduce a weight of the pressure vessel.

摘要： A double-cylinder two-stage compression rotary compressor (10) comprising a first and a second compressors (32 , 34), driven by an electric motor (14), all accommodated in a sealed container (12). The first and the second compressor (32, 34) have respective first and second cylinders (40, 42) accommodating first and second rollers (48, 50), fitted on respective first and second eccentric cams (44, 46). The inner spaces of the first and second cylinders are partitioned by respective first and second vanes (52, 54) to form suction spaces and compression spaces. The two cylinders are separated by an intermediate partition panel (38), which has a central bore (36) for passing therethrough a shaft (16) of the motor (14). The center of the bore (36a) of the intermediate partition panel (38) facing the first roller (48) is offset away from the center-of the shaft (16) to an angular position having a central angle about the center of the shaft in the range of 90±45 degrees with reference to the first vane (52), and the center of the bore (36b) of the intermediate partition panel (38) facing the second roller (50) is offset about the center of the shaft (16) by an angle in the range of 270-360 degrees to increase the sealing areas of the rollers with the intermediate partition panel, thereby decreasing the leakage of the refrigerant gas and increasing volumetric efficiency and pressure efficiency of the compressor.

摘要： Refrigerant exiting a condenser (1) is diverted into first and second parts, with the first part passed to a first intercooler (6) via a first decompression means (3) while the second part is passed to an evaporator (8) via a second decompression means (7). The refrigerant passed to the second decompression means (7) undergoes heat exchange with the intercooler (6). The refrigerant discharged from the evaporator (8) is fed to a first stage low-pressure compression means (32). In the multi-stage compression apparatus, the refrigerant discharged-from the low-pressure compression means (32) is mixed or merged with the refrigerant exiting the intercooler (6) at a merging point (106), and then fed to a second stage high-pressure compression means (34). The displacement volume of the low-pressure compression means (32) is larger than that of the high-pressure compression means(34). Provided between the first intercooler (6) and the merging point (106) is a one-way valve (9) for permitting the flow only in the direction from the first intercooler (6) to the merging point (106). The inventive multi-stage compression refrigeration apparatus may perform refrigeration with suppressed temperature of refrigerant gas discharged from the high pressure compression means (34). The apparatus can attain its stable normal operating condition in a short time. Thus, the inventive refrigeration apparatus has an improved refrigeration efficiency.

摘要： A multi-stage compression refrigeration apparatus (10) includes a compressor having a first stage low-pressure compression means (32) and a second stage high-pressure compression means (34), a condenser (1), a first decompression means (3), an intercooler (6), a second decompression means (7), and an evaporator (8). The refrigerant discharged from the condenser (1) is diverted into first and second parts, with the first part passed to the intercooler (6) via the first decompression means (3) while the second part is passed to the evaporator (8) via the second decompressor (7). The refrigerant passed to the second decompressor (7) undergoes heat exchange with the intercooler (6). The refrigerant discharged from the evaporator (8) is fed to the low-pressure compression means (32). The refrigerant discharged from the intercooler (6) is fed to the high-pressure compression means (34) together with the refrigerant discharged from the low-pressure compression means. The apparatus further comprises a second intercooler (5) downstream of the evaporator (8) so that the second diverted part of the refrigerant may undergo heat exchange in the intercooler (5) prior to entering the evaporator. The inventive apparatus thus may perform refrigeration with an improved efficiency during an early stage of its startup.

摘要： Refrigerant compressed by a first stage compression elements (30) run by a motor (20) is discharged in the closed container (10) via a silencer chamber (35) to cool the motor (20) before the refrigerant is led to a second stage compression element (40). The refrigerant is discharged from the second stage compression element (40) out of the compressor after it is further compressed in the second compression element (40). Thus, the motor (20) is cooled in a simple cooling mechanism during normal operation of the compressor.

摘要： There is provided a rotary compressor capable of preventing deterioration of performance following plug fixing carried out to prevent falling-off of a spring member. The rotary compressor comprises a cylinder constituting a rotary compression element, a roller engaged with an eccentric portion formed in a rotary shaft of an electric element, and eccentrically rotated in the cylinder, a vane abutted on the roller to divide an inside of the cylinder into a low pressure chamber side and a high pressure chamber side, a spring member for always pressing the vane to the roller side, a housing portion of the spring member, formed in the cylinder, and opened to the vane side and a hermetically sealed container side, a plug positioned in the hermetically sealed container side of the spring member, and inserted into the housing portion to fit into a gap, and an O ring attached around the plug to seal a part between the plug and the housing portion. In this case, a space between the cylinder and the hermetically sealed container is set smaller than a distance from the O ring to an end of the plug on the hermetically sealed container side.
