る内燃機関の動弁機構。In a valve operating mechanism for an internal combustion engine, one end of a rocker arm is used as a pivot, and the other end drives a valve, and the position of the pivot is movable to selectively drive or stop driving the valve. The one end of the arm is supported by a plunger slidably fitted within a fixed cylinder, and the plunger and the cylinder wall are provided with overlapping lateral holes, into which a common pin is inserted. A valve mechanism for an internal combustion engine, comprising a device that can selectively move the pin between a position where the pin engages only the plunger and a position where the pin engages both the plunger and the cylinder wall.
