Title:
HIGH-SPEED CAM MECHANISM
Document Type and Number:
Japanese Patent JP2014218905
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To develop a cam mechanism for improving more performance over a prior patent application of "Cam mechanism with steep rise" (Japanese Patent Application No.2013-28576) as a cam mechanism that can be used in "Ignition mechanism of Internal Combustion Engine" (Japanese Patent Application No.2012-276596) filed by the present inventor.SOLUTION: If a rotational speed of a cam is increased in respect to the same cam lift, its rotational angle is increased, resulting in that a pressure angle can be relatively set to a low value. Under application of a method in which a high speed cam rotating at integral multiplication of a basic cam is used to decrease the pressure angle and further it is combined with a symmetrical cam described in "Cam mechanism with steep rise", the high speed cam mechanism enables a steeper rise.
