とを特徴とするバルブ停止装置。A stop device for a valve that is reciprocally driven by a cam to open and close a port, and includes a lifter that is reciprocally driven by the cam, and a lifter that is reciprocally driven by the cam. A transmission member that is driven to open and close and has a hole through which the valve stem can be inserted, and control that rotationally displaces the transmission member around an axis substantially perpendicular to the axis of the valve stem to align the valve stem with the hole. when the control mechanism rotationally displaces the transmission member to a position where the valve stem does not align with the hole, the transmission member reciprocates in conjunction with the movement of the cam, thereby causing the valve to rotate. The above control mechanism opens and closes the port.
When the transmission member is rotationally displaced to a position where the valve stem is aligned with the hole, even if the transmission member reciprocates in conjunction with the movement of the cam, the valve stem is inserted into the hole. A valve stop device characterized in that the above valve does not open a port.
