Description
본 고안은 피스톤, 특히 터보차저 엔진용 피스톤의 냉각구조 개선에 관한 것이다.The present invention relates to an improvement in the cooling structure of pistons, in particular pistons for turbocharged engines.
종래 도 2 에 도시하는 것과같이 터보차저 엔진의 경우 피스톤(10) 냉각을 위하여 몸체 내부에 오일냉각 갤러리(11)가 형성되어 있다.As shown in FIG. 2, in the case of a turbocharged engine, an oil cooling gallery 11 is formed inside the body for cooling the piston 10.
그러나 종래의 경우 A-A 단면도(도 3)를 통해 확인되듯이 오일냉각 갤러리(11)의 오일 유입구(12)는 하면에 하나가 형성되어 있는데 반하여 오일 출구부(13),(14)는 두곳에 형성되어 있기 때문에 오일 출구부(13),(14) 사이의 오일냉각 갤러리가 형성되어 있지 아니한 피스톤 몸체부에 과열을 유발하게 되는 문제점이 있다.However, in the conventional case, one oil inlet 12 of the oil cooling gallery 11 is formed at the lower surface thereof, whereas the oil outlets 13 and 14 are formed at two places, as confirmed by the AA cross-sectional view (FIG. 3). Therefore, there is a problem that causes overheating of the piston body portion in which the oil cooling gallery between the oil outlet portions 13 and 14 is not formed.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는바는 피스톤의 전체 부위에 걸쳐 냉각 효과를 고르게 유지되도록 하는 피스톤 냉각구조를 제공하는데 있다.Accordingly, the present invention has been proposed in view of the above problems, and its object is to provide a piston cooling structure for maintaining the cooling effect evenly over the entire portion of the piston.
본 고안은 상기한 목적을 달성하기 위하여,The present invention to achieve the above object,
피스톤 몸체 내부에 오일을 순환시켜 냉각하는 냉각구조에 있어서,In the cooling structure for cooling by circulating oil inside the piston body,
피스톤 몸체 내부를 360℃ 전원주 방향에 걸쳐 연통하는 고리형의 오일냉각 갤러리와;An annular oil-cooled gallery communicating the interior of the piston body over a 360 ° C power main direction;
상기 오일냉각 갤러리에 오일을 유입시키도록 피스톤 하면으로 부터 천공되는 오일 유입구와; 및An oil inlet formed from a lower surface of a piston to introduce oil into the oil cooling gallery; And
상기 오일 유입구의 반대측의 오일냉각 갤러리 상에 오일을 배출하기 위해 마련되는 오일 유출구와; 를 포함하여 구성되는 것임을 특징으로 한다.An oil outlet provided for discharging oil on the oil cooling gallery opposite the oil inlet; Characterized in that comprises a.

※ 도면의 주요부분에 대한 부호의 설명※ Explanation of code for main part of drawing
1 : 피스톤2 : 오일냉각 갤러리1: Piston 2: Oil Cooling Gallery
3 : 오일 유입구4 : 오일 출구부3: oil inlet 4: oil outlet
이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1 은 본 고안에 의한 피스톤의 냉각구조를 나타내는 피스톤의 저면도이다.1 is a bottom view of a piston showing a cooling structure of a piston according to the present invention.
도면중 부호 1은 피스톤이며 피스톤(1) 몸체내에는 360℃ 전원주 방향에 걸쳐 연통하는 고리형상의 오일냉각 갤러리(2)가 형성되어 있으며 그의 일측에는 피스톤(1)의 저면을 향해 보다 정확히는 오일 분사 방향을 향한 방향으로 오일 유입구(3)가 천공되어 있으며 오일 유입구(3)의 반대측인 오일냉각 갤러리(2) 상에는 하나의 오일 유출구(4)가 천공되어 있다.In the drawing, reference numeral 1 denotes a piston, and in the body of the piston 1, an annular oil-cooling gallery 2 is formed which communicates with the power source in the direction of 360 ° C, and on one side thereof, oil injection is more precisely directed toward the bottom of the piston 1. The oil inlet 3 is perforated in the direction toward the direction, and one oil outlet 4 is perforated on the oil cooling gallery 2 opposite to the oil inlet 3.
이에따라 오일제트로부터 분사되는 오일이 오일 유입구(3)를 통해 오일냉각 갤러리(2)로 들어가 오일냉각 갤러리(2)를 따라 좌우로 갈라져 반바퀴 돌아 나가면서 피스톤(1)을 냉각한 후 오일 유출구(4)를 통해 낙하되어 오일팬으로 회수되어지게 된다.Accordingly, the oil jetted from the oil jet enters the oil cooling gallery (2) through the oil inlet (3), splits left and right along the oil cooling gallery (2), and rotates half a turn to cool the piston (1), and then the oil outlet ( It is dropped through 4) and recovered to the oil pan.
이상과 같은 본 고안에 의한 피스톤의 냉각구조에 의하면,According to the cooling structure of the piston according to the present invention as described above,
오일냉각 갤러리를 피스톤 몸체내에 360℃ 전원주 방향에 걸쳐 링형상으로 연통하도록 마련하고 상호 대향되는 위치에 오일 유입구와 오일 배출구를 하나씩 설치하는 것에 의해서 피스톤의 전체 원주면에 걸쳐서 냉각 효과가 미치지 않는 부분이 없게 되므로 피스톤의 냉각 효율이 향상되며 종래에 비해 20∼50℃ 정도의 냉각 효과를 가져오게 된다.The oil cooling gallery is provided in the piston body so as to communicate in a ring shape in the direction of the main power of 360 ° C, and the oil inlet and the oil outlet are installed in opposite positions one by one so that the cooling effect is not applied over the entire circumferential surface of the piston. Since there is no cooling efficiency of the piston is improved and brings about 20 to 50 ℃ cooling effect compared to the prior art.
