Abstract

본 발명은 왕복동식 압축기의 오일 흡입 방지장치에 관한 것으로, 제 3 도 내지 제 6 도에 도시한 바와 같이, 스코치 요크 방식 압축기에 있어서, 크랭크 축(4)의 상단부가 슬라이더 쉘(14)의 내부에 위치하여, 상기 크랭크 축(4)의 상단부가 슬라이더 쉘(14)에 의해 일부 또는 전부 막힌 구조로 되고, 상기 슬라이더 쉘(14)의 크랭크 축(4) 상단부를 벗어난 피스톤(2) 방향에 급유공(15)이 형성되며, 슬라이더 쉘(14)의 일단부가 막힌 구조로 구성되어 있었으며, 이러한 본 발명은 기존 구조에서 슬라이더 쉘 및 크랭크 축 단면부로 부터 오일이 배출되어 구조물을 타고 들어가거나 공중에 비산되어 흡입 파이프로 바로 들러가느 많은 양의 오일로 인해 압축기의 신뢰성 저하 및 열 싸이클 효율 저하가 유발하는 문제점이 있었으나, 본 발명은 이러한 결함을 방지하여 신뢰성이 높고 효율이 높은 냉동, 열 싸이클을 제공할 수 있게 되는 이점이 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil suction preventing device for a reciprocating compressor. As shown in FIGS. 3 to 6, in the scotch yoke type compressor, the upper end of the crankshaft (4) is inside the slider shell (14). The upper end of the crankshaft 4 is partially or completely blocked by the slider shell 14, and is directed toward the piston 2 beyond the upper end of the crankshaft 4 of the slider shell 14; A hole 15 is formed, and one end of the slider shell 14 is formed in a closed structure. In the present invention, the oil is discharged from the slider shell and the crank shaft end surface in the existing structure, and enters the structure or scatters in the air. Due to the large amount of oil that flows directly into the suction pipe, there is a problem that the reliability of the compressor and the thermal cycle efficiency are deteriorated, but the present invention prevents such defects. There is an advantage to be able to provide a highly reliable and efficient refrigeration, heat cycle.
