Valve opening mechanism

摘要

The present invention is a valve opening mechanism which has been designed so as to be able to open an actuator pin (30), on which a stop (31) is provided that is through-mounted to slide freely facing in a vertical direction in relation to the top of a rocker arm (7) and which is restrained by the bottom of the rocker arm (7) tip at a specified uppermost position, and the engine valves (4), by pushing downward during the exhaust stroke of a rocker arm (7).
