본 고안은 엔진오일분리기에 관한 것으로, 엔진오일분리기에서 블로우바이가스(Blow By Gas)로 부터의 오일이 분리되어지도록 된 엔진오일분리기의 오일드레인구조에 관한 것이다.The present invention relates to an engine oil separator, and relates to an oil drain structure of an engine oil separator in which oil from blow by gas is separated from the engine oil separator.

일반적으로 엔진오일분리기(Engine Oil Seperator)란 엔진운전중에 발생되는 연소가스가 피스톤링과 실린더구멍사이의 틈새 내지는 밸브가이드와 밸브사이의 틈새로 새어나온 엔진오일의 미세입자와 혼합되어진 블로우바이가스로부터 분리시키는 역할을 수행하는 바, 종래에도 이같은 블로우바이가스에서 오일을 분리시키는 엔진오일분리기가 제안되어 엔진에 장착되어 있는데, 종래의 구조는 그 대부분이 엔진오일분리기의 입구쪽으로 유입되는 블로우바이가스로부터 분리된 엔진오일이 드레인구멍을 통하여 드레인되어질 때 블로우바이가스의 역류에 의하여 분리되었던 오일의 일부가 다시 블로우바이가스와 혼합되어지는 문제가 있었다.In general, an engine oil separator is composed of a blow-by gas in which combustion gas generated during engine operation is mixed with fine particles of engine oil leaked into a gap between a piston ring and a cylinder hole or a gap between a valve guide and a valve. The engine oil separator which separates the oil from the blow-by gas has been proposed and mounted in the engine. However, the conventional structure is mainly provided from the blow-by gas flowing into the inlet of the engine oil separator. When the separated engine oil is drained through the drain hole, a part of the oil separated by the reverse flow of the blow-by gas is mixed with the blow-by gas again.

이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 엔진오일 분리기에서 분리된 오일이 블로우바이가스의 역류현상에 의해 다시 블로우바이가스와 혼합되지 않도록 효과적으로 드레인시킬 수 있도록 된 엔진오일분리기의 오일드레인구조를 제공함에 그 목적이 있다.The present invention is devised to solve the above problems, the oil of the engine oil separator which can effectively drain so that the oil separated in the engine oil separator is not mixed with the blow-by gas again by the backflow phenomenon of the blow-by gas The purpose is to provide an oil drain structure.

상기와 같은 목적을 달성하기 위한 본 고안은 헤드커버의 내부 상부면에 부착된 입구를 갖는 엔진오일분리기에 이 입구보다 아래쪽에 위치하는 오일드레인구멍부를 형성시키되, 이 오일드레인구멍부에는 오일드레인안내홈이 형성되어 있으면서 오일저장홈을 갖춘 오일드레인플러그가 상기 드레인구멍부의 나선부에 체결되어진 것이다.The present invention for achieving the above object is to form an oil drain hole located below the inlet in the engine oil separator having an inlet attached to the inner upper surface of the head cover, the oil drain hole in the oil drain guide The oil drain plug having the groove and the oil storage groove is fastened to the spiral portion of the drain hole.

이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안이 적용된 엔진헤드커버의 단면도이고, 제2도 a, b는 본 고안에 따른 오일드레인플러그의 평면도와 단면도로서, 본 고안은 헤드커버(1)의 내부상부면에 부착된 입구(2)를 갖춘 엔진오일분리기(3)에 있어서, 상기 엔진오일분리기(3)의 입구(1)보다 아래쪽에 오일드레인구멍부(4)를 형성시키되, 이 오일드레인구멍부(4)에는 다수개의 오일드레인안내홈(5)이 형성되어 있으면서 오일저장홈(6)을 갖춘 오일드레인플러그(7)가 상기 오일드레인구멍부(4)와 나선식으로 체결되어지는 구조로 되어 있다.1 is a cross-sectional view of the engine head cover to which the present invention is applied, and FIG. 2 is a plan view and a cross-sectional view of the oil drain plug according to the present invention, and the present invention has an inlet attached to an inner upper surface of the head cover 1. In the engine oil separator (3) provided with (2), an oil drain hole portion (4) is formed below the inlet (1) of the engine oil separator (3). The two oil drain guide grooves 5 are formed, and the oil drain plug 7 having the oil storage grooves 6 is helically fastened to the oil drain hole portions 4.

여기서 상기 오일드레인플러그(7)에는 그 하부 머리쪽에 오일저장홈(6)이 형성되고 이 오일저장홈(6)에 연통되면서 오일드레인플러그(7)의 몸체(7a)의 길이방향을 따라 다수개의 오일드레인안내홈(5)이 형성되어져 있다.Here, the oil drain plug 7 has an oil storage groove 6 formed at the lower head thereof and communicates with the oil storage groove 6 along the longitudinal direction of the body 7a of the oil drain plug 7. An oil drain guide groove 5 is formed.

따라서, 이 오일드레인플러그(7)가 상기 오일분리기(3)의 오일드레인구멍부(4)에 체결되어 장착되어짐에 따라 블로우바이가스에 내포된 오일(8)이 분리되어 이오일드레인플러그(7)의 오일드레인안내홈(5)을 따라 사기 오일저장홈(6)에 고여진다.Accordingly, as the oil drain plug 7 is fastened and mounted to the oil drain hole 4 of the oil separator 3, the oil 8 contained in the blow-by gas is separated and the oil drain plug 7 Along the oil drain guide groove (5) of the oil storage groove (6).

즉, 이를 좀더 설명하면 블로우바이가스가 상기 오일분리기(3)의 입구쪽으로 유입되어진후 이 블로우바이가스에서 분리된 오일(8)은 상기 엔진오일분리기(3)의 오일드레인구멍부(4)에 장착된 오일드레인플러그(7)의 오일드레인안내홈(5)을 거쳐 오일저장홈(6)에 고여지는데, 이 엔진오일분리기(3)와 외부쪽의 압력차로 인해 상기 오일(8)이 드레인되어지므로, 블로우바이가스의 역류현상이 발생하지 않는다.In other words, when the blow-by gas is introduced into the inlet of the oil separator 3, the oil 8 separated from the blow-by gas is transferred to the oil drain hole 4 of the engine oil separator 3. The oil drain groove (5) of the mounted oil drain plug (7) is passed to the oil storage groove (6), the oil (8) due to the pressure difference between the engine oil separator (3) and the external drain As a result, the reverse flow phenomenon of the blow-by gas does not occur.

이상 설명한 바와 같이 본 고안에 의하면, 상기 엔진오일분리기(3)의 오일드레인구멍부(4)에 장착된 오일드레인안내홈(5)과 오일저장홈(6)을 갖춘 오일드레인플러그(7)에 의해 블로우바이가스가 역류되지 않아 분리된 오일을 효율적으로 드레인 시킬 수 있게 된다.As described above, according to the present invention, the oil drain plug 7 having the oil drain guide groove 5 and the oil storage groove 6 mounted on the oil drain hole 4 of the engine oil separator 3 is provided. As a result, the blow-by gas is not flowed back so that the separated oil can be efficiently drained.
