Beschreibung
Zusammenfassung:	The present invention relates to a piston of an engine having a double gallery, wherein each gallery, which uniformly fills oil therein during operation, individually sprays oil. A piston of an engine having a double gallery according to the present invention is a piston (30) installed to be elevated within a cylinder block (10) of an engine. Here, an oil gallery (31A)(31B) formed in a circular arc shape such that oil may flow within the piston (30) is formed within the piston (30). Moreover, each of the oil gallery (31A)(31B) takes charge of spraying the oil by an oil jet (12A)(12B) installed at the cylinder block (10) in the same quantity as the oil gallery (31A)(31B). 본 발명은 작동 중 내부에 오일이 고르게 충전되도록 하는 각 갤러리마다 별도로 오일이 분사되도록 한 이중 갤러리가 형성되는 엔진의 피스톤에 관한 것이다. 본 발명에 따른 이중 갤러리가 형성되는 엔진의 피스톤은, 엔진의 실린더 블록(10)의 내부에 승강가능하게 설치되는 피스톤(30)에 있어서, 상기 피스톤(30)의 내부에 상기 피스톤(30)의 내부에서 오일이 유동할 수 있도록 원호형으로 형성되는 오일갤러리(31A)(31B)가 형성되고, 상기 실린더 블록(10)의 설치되고 상기 오일갤러리(31A)(31B)와 같은 수로 설치되는 오일젯(12A)(12B)에 의해 상기 각 오일갤러리(31A)(31B)에 전담하여 오일이 분사되는 것을 특징으로 한다.
