Abstract
Description
Claims (2)
- 상부 외주연에 피스톤 링 및 탑링(14)을 수용하기 위한 링그루브(15)가 형성되는 피스톤에 있어서,상기한 피스톤(12)의 상면(12a)과 탑링(14)이 안착되는 링그루브(15)가 연통되도록 하는 연결구멍(20)을 방사상으로 복수개 형성하되, 상기 연결구멍(20)의 출구측이 탑링(14)의 직상방에 위치하도록 하여 폭발 말기시 연결구멍(20)을 통해 공급되는 연소압에 의해 탑링(14)의 상면이 가압되어 탑링(14)의 오일 긁어내림 동작이 원활해지도록 한 것을 특징으로 하는 탑링의 기능을 향상하기 위한 피스톤 구조.
- 제 1 항에 있어서,상기한 연결구멍(20)은 피스톤(11) 상면(12a)의 중심을 기준으로 90°방향으로 4개가 형성되는 것을 특징으로 하는 탑링의 기능을 향상하기 위한 피스톤 구조.
