る内燃機関のバルブ制御装置。[Scope of Claim for Utility Model Registration] In a valve control device for a valve mechanism that has a plurality of intake valves or exhaust valves per cylinder of an internal combustion engine, a sliding cam that is attached to a camshaft so as to be able to come into contact with and separate from the camshaft is actuated. A predetermined section is installed in the circumferential direction of the cam journal, where the hydraulic passage to the camshaft is open, between the hydraulic chamber that is used to control the internal combustion engine, and the electromagnetic solenoid valve that supplies pressure oil to the hydraulic chamber according to the operating state of the internal combustion engine. An internal combustion engine characterized in that a timing passage is formed with a long groove in a wide range, and the camshaft and the sliding cam are connected only when the hydraulic passage from the electromagnetic solenoid valve matches the timing passage. Valve control device.
