Claims (6)
- 회전 구동장치(12, 112); 및열림 위치와 닫힘 위치 사이에서 회전하면서 작동 가능한 밸브 엘리먼트(14, 114);를 구비한 배기가스 재순환 밸브(10, 110)에 있어서,상기 회전 구동장치(12, 112)에서 상기 밸브 엘리먼트(14, 114)로 회전운동을 전달하는, 캠 곡선(26, 126)을 가지는 캠 엘리먼트(24, 124)를 구비하고상기 밸브 엘리먼트(14, 114)는 열림 상태와 닫힘 상태 사이에서 배타적으로 회전가능한 것을 특징으로 하는 배기가스 재순환 밸브.
- 제 1항에 있어서,상기 회전 구동장치(12, 112), 상기 캠 엘리먼트(24, 124) 및 상기 밸브 엘리먼트(14, 114)의 회전축(16, 116, 18, 118, 130) 중 적어도 2개는 서로 평행한 것을 특징으로 하는 배기가스 재순환 밸브.
- 제 1항 또는 제 2항에 있어서,상기 캠 엘리먼트(24, 124)의 상기 캠 곡선(26, 126)은 70도에서 360도 까지의 각을 커버하는 것을 특징으로 하는 배기가스 재순환 밸브.
- 제1항 또는 제2항에 있어서,상기 캠 곡선(26, 126)이 닫힘 상태에서 시작하여 처음 열리는 구간에서는 완만하게 형성되어 있음으로 인해서, 일정한 회전각에서의 상기 회전 구동장치(12, 112)의 회전은 상기 회전 구동장치(12, 112)의 회전각 보다 더 작은 각으로 상기 밸브 엘리먼트(14, 114)의 회전을 유발시키는 것을 특징으로 하는 배기가스 재순환 밸브.
- 제1항 또는 제2항에 있어서,상기 캠 엘리먼트(24, 124)는 커브 플레이트로 구성되며, 상기 캠 곡선(26, 126)이 천공된 형태로 상기 커브 플레이트에 구비된 것을 특징으로 하는 배기가스 재순환 밸브.
- 제1항 또는 제2항에 있어서,상기 캠 엘리먼트(24, 124)는 회전 가능하게 레버(20, 120)에 장착되어 있는 롤러(22, 122)와 연동되는 것을 특징으로 하는 배기가스 재순환 밸브.
