Abstract
The present invention is relative to an internal combustion engine equipped with a plurality of combustion chambers such to allow the variation of the opening of the valves of said chambers by means of an actuator. The engine according to the invention comprises a cylinder head having a supporting axle (2) on which a plurality of bushings (16, 16′) is mounted. Said bushings are made integral one another in rotation around the supporting axle by means of a plate (12) rigidly connected at least in the direction of rotation.

An endothermic engine, comprising:
- a plurality of combustion chambers each provided with at least one valve and a lever (11) adapted to cause the opening of said valve;
- a camshaft (1) with a plurality of cams adapted to control said levers;
- a cylinder head having a supporting axle (2) on which a plurality of bushings (16, 16′), each of which rotationally supports one of said levers, is rotationally and eccentrically mounted;
- an actuator (8) adapted to cause the rotation of said bushings by a predetermined angle;
- wherein said bushings are made integral one another in rotation around said supporting axle by means of a plate (12) rigidly connected at least in the direction of rotation.
