Abstract
Description
Claims (4)
- 피스톤(2)의 외주연에 상측으로부터 톱링(10), 세컨드링(11), 오일링이 순차적으로 결합되어 있는 피스톤에 있어서,상기 톱링(10)이 결합되는 제 1 링홈(12)의 내측 상단에 단턱(14)을 형성하고, 상기 단턱(14)에 형합되도록 톱링(10)의 내측에 단차부(15)를 형성하여 톱링(10)의 무게가 감소하도록 하여 톱링(10)의 관성력 감소에 의해 피스톤(2) 하강시 톱링(10)의 부상기간이 감소되도록 구성되어지되,상기한 톱링(10)과 제 1 링홈(12) 간의 바깥쪽 사이드클리어런스(C) 보다 단턱(14)과 단차부(15) 간의 안쪽 사이드클리어런스(C1)이 더 작게 하여 톱링(10)의 부상 높이가 감소하도록 한 것을 특징으로 하는 블로바이가스량 감소를 위한 피스톤링구조.
- 제 1 항에 있어서,상기 안쪽 사이드 크리어런스(C1)는 C/2인 것을 특징으로 하는 블로바이가스량 감소를 위한 피스톤링구조.
- 제 1 항에 있어서,상기 세컨드링(11)의 내측에 단차홈(16)을 형성하여 세컨드링(11)이 삽입되는 제 2 링홈(13)의 공간체적이 증가되도록 하여 톱링(10)과 세컨드링(11) 사이의 가스 압력을 낮춰 줄 수 있도록 한 것을 특징으로 하는 블로바이가스량 감소를 위한 피스톤링구조.
