Claims (6)

  1. 서로 평행하지 않는 밸브스템축의 밸브스템에 의해 개방 및 폐쇄되는 위치사이에서 이동할 수 있도록 장착되어서 동시에 작동하도록 된 다수개의 포핏밸브부재(15, 16)와, 상기 밸브스템의 축을 가로지르는 방향으로 설치된 로킹축(23A)을 중심으로 요동할 수 있도록 장착된 로커(23, 24)를 갖추고 있되, 이 로커(23, 24)는 상기 각각의 밸브가 밸브스템의 끝면과 접촉하게 하는 태피트(80)와 접촉하게 되는 밸브스템을 갖추고 있고, 상기 이 밸브스템의 길이는 상기 태피트들이 로커축을 중심으로 동일평면상에 위치하지 않도록 되면서, 상기 각 밸브들이 동일평면상에 위치되지 않게 되는 한편, 밸브리프트의 운동이 중간부분에 이르게 될 때 로커축으로부터 태피트가 밸브스템의 끝면과 접촉되는 점을 있는 선분이 밸스스템축에 직교하도록 구성된 포핏밸브 조립체.
  2. 서로 평행하지 않은 밸브스템축의 밸브스템에 의해 개방 및 폐쇄되는 위치사이에서 이동할 수 있도록 장착되어서 동시에 작동하도록 된 다수개의 포핏밸브부재(15, 16)와 상기 벨브스템축을 가로지르는 방향으로 설치된 로킹축(23A)을 중심으로 요동할 수 있도록 장착된 로커(23, 24)를 갖추고 있되, 이 로커는 상기 각각의 밸브가 밸브스템의 끝면과 접촉하게 하는 태피트와 접촉하게 되는 밸브스템을 갖추고 있는 포핏밸브조립체에 있어서, 로커축의 축심으로부터 각 밸브스템의 축심에 수직되게 연장되는 선분이 이루는 사잇각과 각 밸브스템축의 사잇각이 동일하게 되고, 각 밸브스템의 길이는 태피트가 밸브스템에 동시에 접촉하도록 된 것을 특징으로 하는 포핏밸브조립체.
  3. 제 1항에 있어서, 상기 밸브 스템축은 로커축(23A)으로부터 동일거리에 위치하고 있는 것을 특징으로 하는 포핏밸브조립체.
  4. 제 2항에 있어서, 각 밸브에 형성된 태피트패드(84)는 로커(23, 24)에 관절연결되어 있으면서, 이와 관련된 밸브부재(15, 16)의 끝면에 미끄럼 접촉하는 접촉면을 갖추고 있고, 로커축(23A)에 대해 상기 태피트패드(84)가 관절연결되는 중심의 각도가 상기 양쪽 밸브스템축 사이에 형성된 각도와 동일하도록 된 것을 특징으로 하는 포핏밸브조립체.
  5. 제 4항에 있어서, 상기 각 밸브는 로커의 운동에 따라 밸브리프트가 중간점에 이르게 될 때 로커축으로부터 상기 관절이음의 중심을 잇는 선분이 밸브부재(15, 16)의 축에 대해 직각을 이루도록 된 것을 특징으로 하는 포핏밸브조립체.
  6. 제 5항에 있어서, 밸스프템축은 로커축(23A)으로부터 동일거리에 위치하도록 된 것을 특징으로 하는 포핏밸브조립체.
