Abstract

본 발명은 로터리 밀폐형 압축기의 베인 및 실린더 슬롯 마모감소장치에 관한 것으로 특히 압축시 베인 양단에 걸리는 냉매압 차이로 인한 베인과 실린더 슬롯의 국부적인 집중하중을 제거하여 그 부분의 마멸을 방지하도록 한 것으로서, 압축실에서 압축된 냉매를 실린더 슬롯과 베인 사이로 유입시켜 냉매에 의하여 국부적인 집중하중을 방지할 수 있도록 한 냉매 유입수단은 일단이 압축실과 통하도록 실린더에 형성한 유입공과, 상기 유입공의 타단은 실린더 슬롯과 베인 사이에 형성된 공간부와 통하도록 구비한 것이다.The present invention relates to a vane and cylinder slot wear reduction device of a rotary hermetic compressor, in particular, to prevent local wear of the vanes and cylinder slots due to the difference in refrigerant pressure across the vanes during compression. Refrigerant inlet means for introducing the refrigerant compressed in the compression chamber between the cylinder slot and the vanes to prevent local concentrated load by the refrigerant is the inlet hole formed in the cylinder so that one end is in communication with the compression chamber, and the other end of the inlet hole Is provided to communicate with the space formed between the cylinder slot and the vane.
