摘要： A two stage rotary compressor is disclosed and includes first and second cylinders (38,40) separated by an intermediate partition plate (36) and first and second compressing elements (42,44) disposed in the first and second cylinders (38,40) respectfully, the compressing elements (42,44) being formed on a rotary shaft (16) spaced from each other by a portion of the shaft (90) that extends through an aperture (36a) in the intermediate partition plate (36). The portion (90) of the shaft (16) between the compressing elements (42,44) has a larger cross-sectional area than the cross sectional area of the remainder of the shaft (16).

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.
