Abstract

PURPOSE: A high-low two-action one unit cam is set up on a cam shaft so that the cam can move to an axial direction, and let it displace in proportion to the highlow load/rotational frequency of an engine so as to come into contact with a rocking arm. In so doing, aimed at is to change the valve-timing of an engine automatically.
