Abstract

PURPOSE:To properly push a valve stem in the axial direction by disposing the shaft of a sub rocker arm to be parallel with the plane perpendicular to a valve stem and also to be perpendicular to the stem in the swinging range of the sub rocker arm. CONSTITUTION:Each sub rocker arm shaft 11 is arranged to be parallel with the plane perpendicular to a valve stem 4a or 5a and also to be perpendicular to the valve stem 4a or 5a in the swinging range of a sub rocker arm 10. Regardless of any direction in which a rocker arm 8 pushes the sub rocker arm 10, it constantly pushes a related stem 4a or 5a of a valve 4 or 5, thereby improving the durability of the valves.

によりノ々ルブステムを軸芯方向に押圧している。In general, in a valve train in which a camshaft drives a plurality of knob stems arranged radially in a combustion chamber, the suppression direction of the rocker arm and the iib core direction of the knob stem coincide with each other. A twin blocker arm is interposed between the rocker arm and the knob stem, thereby pressing the knob stem in the axial direction.

。The purpose of Kokusei BA is to obtain a device in which the blocker arm is always suppressed by the axial force of the nonoru stem no matter which direction the rocker arm pushes the blocker arm. In a valve operating system for an internal combustion engine in which a camshaft is linked to a camshaft through a rocker arm and a camshaft through a rocker arm and a camshaft, the shaft of the blocker arm is connected to the camshaft through a rocker arm and a camshaft. It is characterized in that it is disposed parallel to a perpendicular plane and perpendicular to the nodal stem in the swing range of the blocker arm.
