A new type driven valve system far combustion engines has been presented, in which the cam is macte of permanent magnet, and the roller rocker arm is made of cylindrical permanent magnet. In this system, an attractive force between the cam and the rocker arm due to the magnetic force suppresses jumps and bounces. This makes the fiction in the driven valve system decrease. Hence, friction torque is decreased by use of this system. This implies that the energy loss decreases. In addition, since bounce phenomena is suppressed by the attractive force, noise due to the bounce is also suppressed in the present system. The analysis for obtaining the critical speed has been presented, and to validate the theoretical results, experimental test has been carried out. It is clarified that the present system is valid for the driven valve system for combustion engines.
