Abstract

본 발명의 목적은 자동차 내연기관 흡배기밸브의 행정 가변장치를 제공함에 의해 달성되게 되는데, 이 가변장치는 밸브 스템앤드와 캠의 사이에 차속에 따른 제어수단에 의해 구동하는 유압회로와 연동되는 가변수단을 개재하여 차속에 비례하여 밸브의 행정거리를 가변시키게 하고 있다. 따라서 차속에 비례하여 밸브의 행정을 가변시키어 연비는 물론, 성능향상시키게 된다.The object of the present invention is achieved by providing a stroke variable device for an automobile intake and exhaust valve, which variable device is interlocked with a hydraulic circuit driven by a control means according to the vehicle speed between the valve stem and the cam. The stroke distance of the valve is changed in proportion to the vehicle speed via the. Therefore, the stroke of the valve is changed in proportion to the vehicle speed, thereby improving fuel economy and performance.
