Abstract

본 발명은 압축기의 윤활구조에 관한 것으로, 오일이 흡입머플러를 통해 실린더로 흡입되는 것을 방지하기 위해, 크랭크축(5)의 오일통로(5a)와 연통되게 슬라이더(20)와 크랭크축(5) 외주면에 오일유로가 형성되고, 피스톤(10)의 슬라이더쉘(11)에 오일주입구(11a)가 형성되며, 피스톤(10)은 외주면에 내부와 관통되게 윤활구멍(10a)이 형성되고, 슬라이더쉘(11)쪽 상단 외주면에 오일흡입구(11b)가 형성되고, 하부에 오일배출구(11c)가 형성되도록 구성하여, 크랭크핀(5b) 상단에서 피스톤(10) 슬라이더쉘(11)의 오일주입구(11a)를 통해 피스톤(10) 외주면 윤활을 하고, 크랭크핀(5b)과 슬라이더(20)의 오일유로(20a)를 통해 이송되는 오일이 피스톤(10) 내부로 보내져, 윤활구멍(10a)을 통해 피스톤(10)의 외주면과 실린더(7) 사이의 윤활을 하게 되며, 피스톤(10) 내에 일정량 이상의 오일이 유입되면 오일 배출구(10c)를 통해 배출되도록 하므로, 오일이 비산되는 것을 방지하는 밀폐형 전동압축기의 윤활구조이다.The present invention relates to the lubrication structure of the compressor, in order to prevent the oil is sucked into the cylinder through the suction muffler, the slider 20 and the crankshaft (5) in communication with the oil passage (5a) of the crankshaft (5) An oil flow path is formed on the outer circumferential surface, an oil inlet 11a is formed on the slider shell 11 of the piston 10, and a lubrication hole 10a is formed on the outer circumferential surface to penetrate the inside, and the slider shell An oil inlet 11b is formed at an outer circumferential surface of the upper side of 11 and an oil outlet 11c is formed at a lower portion thereof, and an oil inlet 11a of the slider shell 11 of the piston 10 is formed at the upper end of the crank pin 5b. Lubrication of the outer circumferential surface of the piston (10) through the), and the oil transported through the oil passage (20a) of the crank pin (5b) and the slider 20 is sent into the piston (10), the piston through the lubrication hole (10a) Lubricating between the outer circumferential surface of (10) and the cylinder (7), a certain amount of When the oil is introduced so that the discharge through the oil discharge port (10c), a lubricating structure of a hermetic electric compressor that prevents oil scattering.
