Abstract

내연기관의 여러 상부 밸브들(5, 6)이 제어 캠을 통해 동시에 작동되므로써 종래의 태핏들(7, 8) 및 밸브 스프링들(20, 21)을 사용할 수 있도록 하기 위하여, 태핏들(7, 8) 및 기초부 표면들을 가로질러 가로대가 놓이고, 이 가로대 위에서 상부 밸브들(5, 6)의 축들 사이에 제어 캠(18)이 직접 또는 로커 아암의 삽입에 의해 작동되도록 제안된다. 가로대(14)는 상부 밸브들(7, 8) 사이에 돌출한 가로대 돌출부(16)에 의해 결합이 보증된다.

Description

동시에 작동하는 적어도 두 개의 엔진 밸브들을 위한 밸브 구동장치(DRIVE UNIT FOR AT SEAST TWO SIMULTANEOUSLY LPERATING ENGINE VALVES)
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 따른 밸브 구동장치의 단면도이다,
제2도는 제1도의 밸브 구동장치의 평면도이다,
제3도는 두 개의 티핏(tappet)위에 고정된 제1도의 밸브 구동장치의 가로대의 사시도이다.

Claims (5)

  1. 내연기관에서 가스교환을 위해 동시에 작동하는 적어도 두 개의 상부 밸브들을 위한 구동장치에 있어서, 동시에 작동하는 밸브들 구룹의 상부 밸브들(5, 6) 각각에 그 자신의 태핏들(7, 8;7´, 8´) 및 밸브 스프링들(20, 21)이 제공되며, 이 태핏들(7, 8;7´, 8´)로부터 떨어져 대면하고 있는 가로대 표면(17)은 캠축(19)의 제어캠(18, 18´)에 의해 위로 작동되는 것을 특징으로 하는 밸브 구동장치.
  2. 제1항에 있어서, 평평한 접촉 표면들(15)을 가진 가로대(14)가 태핏들(7, 8;7´, 8´)의 평평한 기초부 표면들 위에 놓여 있으며, 수평면(17)으로부터 돌출된 가로대의 돌출부(16)가 태핏들(7, 8;7´, 8´)의 바깥 원주면들 사이에 결합되는 것을 특징으로 하는 밸브 구동장치.
  3. 제1항 및 2항에 있어서, 제어캠들(18, 18´)이 가로대들(14)위에서 직접 작용하는 것을 특징으로 하는 밸브 구동장치.
  4. 제1항 및 2항에 있어서, 제어 캠이 로커 아암의 삽입을 통해 가로대 위에서 작용하는 것을 특징으로 하는 밸브 구동장치.
  5. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
