본 고안은 엔진의 실린더에 장착되는 피스톤의 열부하를 감소시키기 위해 상기 피스톤 내부에 형성된 오일구멍구조에 관한 것이다.The present invention relates to an oil hole structure formed inside the piston to reduce the heat load of the piston mounted to the cylinder of the engine.
일반적으로 엔진의 실린더에 장착되는 피스톤의 머리부위는 연소실의 일부를 형성하고 실린더와 더불어 고온·고압을 받도록 되어 있는 까닭에 냉각수 내지는 외기로 직접 냉각할 수 없도록 되어 있으나 오일을 이용하여 냉각할 수가 있도록 되어 있다.Generally, the head of the piston mounted on the cylinder of the engine forms part of the combustion chamber and is subjected to high temperature and high pressure together with the cylinder, so it cannot be cooled directly with coolant or outside air, but can be cooled with oil. It is.
통상 피스톤의 열부하를 감소시키기 위해서 상기 피스톤의 머리부위에는 오일갤러리(Oil Gallery)가 형성되어 있으며, 이 오일 갤러리를 통해 오일이 유입되어 피스톤을 냉각시키는 바, 종래의 피스톤의 오일구멍은 제 3 도에 도시된 바와 같이 오일(16)을 피스톤의 오일공급구멍(13)으로 유입시킬때 오일(16)이 상기 피스톤의 오일갤러리(12)에 형성된 평면형태의 오일접촉연결부(14)에 직접 닫아 반사되어짐에 따라 유입되는 오일(16)의 흐름이 방해되어진 뿐만 아니라 더욱이 정확한 양의 오일이 피스톤의 오일갤러리(12)로 골고루 분배되지 못함에 따라 피스톤의 불균일한 냉각을 야기시키는 문제점이 있었다.In order to reduce the heat load of the piston, an oil gallery is formed at the head of the piston, and oil flows through the oil gallery to cool the piston. When the oil 16 is introduced into the oil supply hole 13 of the piston as shown in FIG. 16, the oil 16 directly closes and reflects on the planar oil contact connecting portion 14 formed in the oil gallery 12 of the piston. Not only is the flow of oil 16 introduced as it is impeded, moreover, there is a problem that causes the non-uniform cooling of the piston as well as the exact amount of oil is not evenly distributed to the oil gallery 12 of the piston.
이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출해 낸 것으로, 피스톤의 균일한 냉각을 도모하고 유입되는 오일의 원활한 흐름을 유도하는 엔진용 피스톤의 오일구멍구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to provide an oil hole structure of the piston for the engine to promote the uniform cooling of the piston and induce a smooth flow of oil.
상기와 같은 목적을 달성하기 위한 본 고안은 피스톤 헤드부 내부에 환형형상으로 형성된 오일갤러리와 이 오일갤러리에 연통되는 오일공급구멍을 갖추어 이루어진 피스톤의 오일구멍구조에 있어서, 상기 오일갤러리와 오일공급구멍의 접촉연결부에 유입되는 오일을 유도 안내하도록 라운드형상으로 돌출된 오일 안내돌기부가 형성되어 이루어져 있다.The present invention for achieving the above object in the oil hole structure of the piston having an oil gallery formed in an annular shape in the piston head portion and the oil supply hole communicating with the oil gallery, the oil gallery and the oil supply hole The oil guide protrusion protruding in a round shape is formed so as to guide the oil flowing into the contact connecting portion of the.
이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안에 따른 엔진용 피스톤의 오일구멍구조는 제 1 도 및 제 2 도에 도시된 바와 같이 피스톤(1)의 헤드부(1a) 내부에 환형으로 형성된 오일갤러리(2)와 이 오일갤러리(2)에 연통된 오일공급구멍(3)을 갖추어 이루어진 구조에 있어서, 상기 오일갤러리(2)와 오일공급구멍(3)의 접촉연결부(4)에 라운드형상으로 돌출된 오일안내돌기부(5)가 형성되어져 있는 것은 특징으로 한다.The oil hole structure of the piston for the engine according to the present invention is an oil gallery (2) and the oil gallery (2) formed in an annular shape inside the head (1a) of the piston (1) as shown in FIGS. In the structure consisting of an oil supply hole (3) connected to the), the oil guide projection (5) protruding in a round shape is formed in the contact connecting portion (4) of the oil gallery (2) and the oil supply hole (3) It is characterized by being done.
이와 같이 이루어진 본 고안은 제 2 도에 도시된 바와 같이 오일(6)이 화살표 방향으로 피스톤(1)의 오일공급구멍(3)을 따라 유입되어질때 이 오일(6)은 오일갤러리(2)에 형성된 라운드 형상으로 돌출형성된 오일안내돌기부(5)에 의해 사방으로 균일하게 안내되어 흘러 유입되어짐에 따라 피스톤(1)의 오일갤러리(2)에 정량적인 오일분배를 유도하여 냉각효과를 원활하게 수행할 수 있도록 되어 있다.The present invention made in this way, when the oil (6) is introduced along the oil supply hole (3) of the piston (1) in the direction of the arrow as shown in Figure 2 the oil (6) to the oil gallery (2) As it is uniformly guided and flows in all directions by the oil guide protrusion 5 protruding in the formed round shape, the cooling effect can be smoothly performed by inducing quantitative oil distribution to the oil gallery 2 of the piston 1. It is supposed to be.
상기와 같이 본 고안은 피스톤(1)의 오일갤러리(2)을 오일공급구멍(3)의 접촉연결부(4)에 오일안내돌기부(5)를 형성시킴으로서 피스톤(1)을 냉각시키는 오일의 정량적인 분배를 유도하여 피스톤의 냉각성능을 증대시킬 수 있는 잇점이 있다.As described above, the present invention provides a quantitative amount of oil for cooling the piston 1 by forming an oil guide protrusion 5 at the contact connecting portion 4 of the oil gallery 2 of the piston 1. There is an advantage that can increase the cooling performance of the piston by inducing distribution.
