A decompression device for an internal combustion engine in which the control parts which open and close the exhaust valves of the combustion chambers include a rocking lever acting on the valve. The decompression device includes an eccentric bearing on which the rocking lever is freely mounted, rotation of the eccentric bearing thus moving the axis of the rocking lever to prevent full closing of the exhaust valve, that is, provide decompression of the chamber. The eccentric bearing may be turned to reference position at which it permits full closing of the exhaust valve by either manual or automatic means. |
