Abstract

The present invention relates to an internal combustion engine comprising at least one cylinder (10, 12, 14, 16) having intake means with an intake valve (22), exhaust means with an exhaust valve (32), and control means (40, 42) for opening / closing the valves, said control means comprising control means (44) and means for transmitting movement and effort (56) between said means control and the check valve.
According to the invention, the movement and effort transmission means (56) comprise a rocker arm (58) with at least two rockers (72, 74) disengageable from a sole plate (62) controlling the movement of said valve.
