Abstract

PURPOSE: To obtain a multi-stage cam with which an engine having improved efficiency is realized, by making the radius of slope arched portion as large as possible to decrease the face pressure between the cam and cam roller in accordance with the load.
CONSTITUTION: Multi-stage exhaust cam for static pressure supplying engine is equipped with heavy load cam 1 and light load cam 2. The heavy load cam 1 has the width b necessary to suppress the face pressure between the operating cam and cam roller 3 below specific level during the interval from immediately after opening of cam 2 untill 10 degree of opening, while low load cam 2 has width c where said cams 1, 2 are coupled through slope a-1. The slope a-1 is formed with an arch having radius R-1 which passes through point X-1 on said cam 1 while contacts with said cam 2 at point Y-1 to achieve desired purpose.
