Abstract

PURPOSE: To prevent a suction/exhaust valve from buoyed up by inertial force during high-speed rotation of engine, by applying hydraulic pressure to a valve spring through a spring seat.
CONSTITUTION: A tappet 5 is provided at the top of a valve stem 4 of the suction/ exhaust valve 3 in contact with a cam 6, which is driven by a cam shaft. The spring seat 8 is provided together with an auxiliary spring 13 in a sliking hole 7 of a cylinder head 7 containing the tappet 5. The valve spring 10 is installed between the valve seat 8 and the bottom of the sliding hole 7. A pressure chamber 12 is defined between the tappet 5 and the seat 8 so that lubricating oil can flow into the chamber 12 from a passage 14. Therefore, the pressure of the oil corresponding to the rotational frequency of the engine is applied to the pressure chamber 12 and the valve 3 is tightly fitted on a valve seat while the engine is rotating at a high speed
