たことを特徴とするエンジンの動弁装置。 A pair of valve bodies disposed on both sides of the guide shaft are connected via a bridge body, and this bridge body is supported so as to be movable up and down along the guide shaft, and the bridge body is normally connected to both the valve bodies. held in place by the biasing force of the valve spring in the body;
As the rocker arm swings, the bridge body is moved up and down from a predetermined position along the guide shaft against the urging force of the valve springs of the two valve bodies, and the two valve bodies are opened and closed. In the valve device, a compressible fluid supply mechanism is provided for supplying compressible fluid into a guide shaft insertion hole formed inside the bridge body, and the compressible fluid is filled into the guide shaft insertion hole of the bridge body. A valve operating device for an engine, characterized in that a pressure chamber is formed that generates a biasing force in the same direction as the biasing force of the valve spring when the bridge body moves up and down.
