    • A hermetic compressor capable of preventing malfunction due to impurities trapped between contact portions of a crankshaft and a crankshaft supporting frame when the crankshaft rotates in a hollow portion of the frame. The hermetic compressor comprises the frame having the hollow portion, the crankshaft rotatably inserted in the hollow portion, a balance weight provided at one end of the crankshaft, and a thrust portion formed at the frame to support the crankshaft. An impurities discharge passage is formed at an outer circumferential surface of the crankshaft that comes into frictional contact with the thrust portion of the frame to guide impurities, mixed with the oil, out of the crankshaft. Correspondingly, a plurality of discharge guiding grooves is formed at the thrust portion of the frame to guide the oil and the impurities, having passed through the impurities discharge passage of the crankshaft, out of the thrust portion.
    • 一种封闭式压缩机,其能够防止当曲轴在框架的中空部分中旋转时由于夹在曲轴的接触部分和曲轴支撑框架之间的杂质引起的故障。 封闭式压缩机包括具有中空部分的框架,可旋转地插入中空部分中的曲轴,设置在曲轴一端的平衡重,以及形成在框架处以支撑曲轴的止推部分。 在与框架的推力部摩擦接触的曲轴的外周面形成有杂质排出通道,以将与油混合的杂质引导出曲轴。 相应地,在框架的推力部分处形成有多个排出引导槽,以将已经通过曲轴的杂质排出通道的油和杂质引导出推力部分。
