の動弁装置。[Scope of Claim for Utility Model Registration] In a cylinder head in which an intake port and an exhaust port are formed in a cross-flow type, the cylinder head is installed between the intake port and the exhaust port along the axial direction of the intake/exhaust port. A cylindrical rotary valve driven by a valve shaft is disposed, a first notch is formed in one end face of the rotary valve, a second notch is formed in the other end face, and the first notch is formed in the other end face of the rotary valve.
A second notch is formed at a position where the intake/exhaust port communicates with the combustion chamber at a preset valve timing, and a combustion chamber wall surface is formed on the outer peripheral surface of the rotary valve, and the intake/exhaust port is connected to the combustion chamber. An annular groove opening toward the rotary valve is formed around the circumference, and an annular sealing spacer whose tip portion contacts the end face of the rotary valve is fitted into the annular groove, and a rear part of the sealing spacer is formed. A valve train for an internal combustion engine, characterized in that it is configured to introduce a predetermined hydraulic pressure into the valve.
