Description

내연기관에 대한 유냉피스톤
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 1 도는 이 발명에 따르는 피스톤의 단면으로 표시된 측면도임.

Claims (2)

  1. 냉각실이 인도 구멍들을 거쳐서 내부의 냉각실과 연결되어 있으며, 여기서 쉐이커로서 작용하고 있는 내부의 냉각실은 한편으로는 피스톤축(shaft)쪽을 가리키고 있는 반경방향의 폐쇄된 하부의 환형도관과 다른 한편으로는 피스톤 저면쪽을 가리키고 있는 반경방향으로 폐쇄되어 있는 상부의 환형도관을 가지며, 그리고 또 밖으로부터 안으로 향하여 관류하고 있는 냉각유를 위하여 사용되는 중앙의 배출개구를 설치하고 있는 그러한 외부의 환형의 냉각실을 가지는 내연기관을 위한 유냉피스톤에 있어서, 피스톤 저면(11)으로부터 나오고 있으며 내부의 냉각실(9)로 중앙으로 돌출하고 있는 돌출부(16)가 냉각유에 대한 전향-안내면을 형성하기 위하여 이 돌출부의 횡단면적에 있어서 피스톤축(15)과 수직인 평면과 관련하여 하부의 환형도관(10)의 방향쪽으로 확장되어 있는 것을 특징으로 하는 유냉피스톤.
  2. 제 1 항에 있어서, 돌출부(16)는 내부냉각실(9)쪽으로 개방된 요입부(17)가 형성되어 있는 것을 특징으로 하는 유냉피스톤.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
