Document Type and Number:
Japanese Patent JPS627906
Kind Code:
A
Abstract:
PURPOSE:To make it easy to control the tappet clearance of the tappet mechanism of an internal-combustion engine, by setting one end of a rocker arm, the other end of which drives a valve shaft, on the outside of the valve stem, and setting a spherical pivot with a clearance control mechanism, at this former end of the rocker arm. CONSTITUTION:The center part of a rocker arm 21 whose one end makes contact with the end of a valve shaft 12, is operated by a cam 26, and the other end of this rocker arm 21 is equipped with a spherical pivot 22, and becomes a fulcrum of the rocker arm 21. This spherical pivot 22 is equipped with a screw 21, and the tappet clearance is adjusted by rotating the head 226 with a driver. As this spherical pivot 22 is set on the outside of an engine, with respect to the valve stem 12, the rotation control can be performed easily, as a rocker cover 28 is taken off.
