Abstract
A prechamber in the cylinder head of an internal combustion engine is fed with a rich air-fuel mixture by means of a valve comprising a flexible blade element which normally rests on a flat seat. The actuator control for opening of the blade element is effected on the one hand by natural aspiration of the cylinder and on the other hand by a cam element carried by a cam shaft and directly acting on the flexible blade element.
