Valve pause device of internal-combustion engine

Abstract

Abstract PURPOSE:To enable change-over of operation and pause of a valve with simple construction by energizing an end pivot of a rocker arm to operating position of the valve by a spring and enabling fixing of the pivot by a rotary rod. CONSTITUTION:An end pivot of a rocker arm transmitting lift of a cam 4a to a valve 3 is composed of a pivot axle 10 and a sliding cylinder 11, and the sliding cylinder 11 is pressed up by a spring 8 and energized to the operating position of the valve. A rotary rod 14 is provided in the vicinity of the sliding cylinder 1 and the rod 14 is formed so as to be fit to the notch of the sliding cylinder 11 in semi-circular shape. A spring 16 energizes the rotary rod 14 to two extreme end positions and when the rod is in operating side of the valve, the sliding cylinder 11 is fixed to the operating position of the valve and when it is in pause position, sliding of the sliding cylinder 11 is allowed to pause motion of the valve.
