Abstract
The present invention pertains to a valve actuating device for an internal combustion engine, comprising a magnetic blade controlling the position of the valve and cooperating for this purpose with at least one magnetic circuit comprising at least one magnet for attracting the blade alternately toward a first end position in which the valve is in the closed position and a second end position in which the valve is in the open position. A coil with springs controls the displacement of the blade from one end to the other. The magnetic circuit includes two non-coplanar parts, each of which is approximately C-shaped. A first coil surrounds the main branch of the first part and a second coil surrounds the main branch of the second part. At least one magnet connects the lateral faces opposite the two parts. The corresponding ends of the open branches are approximately coplanar.
