Abstract

PURPOSE:To have an engine with high rotation and high output by driving the intake/exhaust valve of internal-combustion engine by a crank mechanism. CONSTITUTION:A crank shaft B is coupled with a connecting rod and crank shaft by a bolt A, and the revolving motion of this crank shaft is converted into reciprocative motion to move a valve I. Spring G is welded to the piston F and valve. Thereby the number of revolutions of the engine can be increased to assure high output.

Friction occurs between the barb and the valve (η), and as it is used for a long time, it gradually decreases.Also, when the barb and the valve (which have high synchronous rotation) develop inertia and reach a rotational range, The rotation of the engine stops increasing.This invention is based on the cam 4 and valve (Y).
The first valve (
2) The purpose is to reduce the weight between +IJJ fO1 and its inertia, thereby achieving high engine rotation and high output.
