  • Hermetic motor-driven compressor
    Patent number: 6680550
    Abstract: In a hermetic motor-driven compressor, a first gas passage is formed by a space between a linear section in a motor stator and a hermetic container, and a second gas passage in parallel with the first gas passage is formed by through holes in the motor stator. The through holes constituting the second gas passage are disposed outside of a circle inscribed in the linear section in the stator. The through hole is shaped like a bow, and an arch shape of the outer periphery thereof has a curvature larger than that of the outer circumference of the stator.
