Abstract

연소 장치의 구동 밸브는 유압 이동 가능한 커플링 부재로 서로 연결된 위치에서, 그리고 연결되지 않은 위치에서 독립적으로 서로 이동되는 두 개의 인접한 상승 전달 부재로 이루어진다. 상승 전달 부재(태핏 또는 레버 부재)는 캠축의 캠과 연동하며 이는 다른 캠 통로로 형성된다. 또한 다른 상승 진행하는 캠 통로는 상승 전달 부재와 연동한다. 연소 장치의 구동 시에 명백하지 않은 조정 상태를 방지하기 위해, 그리고 커플링 부재의 이동을 위한 각 조정 과정시 충분한 시간을 이용하기 위해 이는 바 부재와 연동하며, 바 부재는 캠 통로에 의존하여 폐쇄 및 개방된다.The drive valve of the combustion device consists of two adjacent raised transmission members which move independently of one another in a position that is connected to each other and in a non-connected position with a hydraulically movable coupling member. The lift transmission member (tappet or lever member) cooperates with the cam of the camshaft, which is formed by another cam passage. In addition, another upwardly moving cam passage cooperates with the upwardly transmitting member. In order to avoid unclear adjustments during the operation of the combustion device, and in order to make use of sufficient time in each adjustment process for the movement of the coupling member, this cooperates with the bar member, which bar member is closed depending on the cam passage. And open.
