る内燃機関の弁装置。 In a valve device for an internal combustion engine equipped with an intake valve and an exhaust valve that open and close an intake port and an exhaust port of a cylinder head, respectively, at least one of the intake valve and the exhaust valve is constituted by a piston valve, and the piston valve is connected to the cylinder head. The valve is fitted into the valve fitting chamber of the head so as to be slidable along the axial direction for a predetermined stroke, and the valve opening cam and valve closing cam are respectively formed on the circumferential surface of the camshaft which rotates in conjunction with the engine. The piston valve is connected to a first rocker arm and a second rocker arm that are in sliding contact and swing by the rotation of these cams.
A valve device for an internal combustion engine, characterized in that the piston valve is driven to open and close by the rocking motion of the rocker arm.
