弁強制開閉装置。 A valve forcing device for an internal combustion engine in which a camshaft has a valve-opening cam that opens the intake and exhaust valves via a valve-opening rocker arm, and a valve-closing cam that closes the intake and exhaust valves via a valve-closing rocker arm. The opening/closing device is characterized in that the valve-closing rocker arm is engaged with a retainer fixed to the valve shaft of the intake and exhaust valve, and the valve-closing rocker arm is supported by a pivot whose height can be adjusted at the center of the valve-closing rocker arm. Forced valve opening/closing device for internal combustion engines.
