Abstract

PURPOSE: To reduce the impact of a dynamic valve device for an internal combustion engine upon opening or closing of the valve, prevent the noise, and to improve the durability of the valve system by intaking part of the bottom area of a valve lift by utilizing an oil tappet to thereby lower the valve lift.
CONSTITUTION: In a dynamic valve device for an internal combustion engine for opening or closing a valve via a rocker arm (not shown), an oil tappet 2 and a push rod 3 upon revolution of a cam 1 rotating by the engine, the oil tappet 2 incorporates a reciprocating tappet body 6 at the barrel in a cylinder block 4, first piston 7 seated with the push rod 3 in the body 6 and free piston (second piston) 10 urged upwardly by a spring 9 in the atmospheric chamber 8 in such a manner that control oil is introduced through oil passages 11, 12 and chack valve 13 into the chamber 15. The piston 7 is inserted into a cylindrical piston 22 within the cylinder 21.
