Title (EN) DEVICE FOR CONTROLLING THE MOVEMENT OF A VALVE, IN PARTICULAR OF AN INTAKE VALVE, OF AN INTERNAL ENGINE
(FR) DISPOSITIF DE COMMANDE DE DÉPLACEMENT DE SOUPAPE, EN PARTICULIER, DE SOUPAPE D'ADMISSION DE MOTEUR À COMBUSTION INTERNE
Abstract: front page image
(EN)The control device comprises an electromagnet (3) adapted, when energised, to retain the valve (1) in the retracted closed position, a first spring (7) associated with the valve (1) and tending to urge it towards the open position, and a second spring (8) also associated with the valve (1) and tending to oppose its transition into the open position. The arrangement is such that when the electromagnet (3) is de-energised, the valve (1) moves in acceleration towards the open position under the action of the first spring (7) until the action of the latter stops, and then the valve (1) moves in deceleration into the open position under the action of the second spring ( 8 ).
(FR)L'invention concerne un dispositif de commande comprenant un électro-aimant (3) conçu, lorsqu'il est excité, pour maintenir une soupape (1) en position fermée rétractée, un premier ressort (7) associé à la soupape (1) et tendant à la pousser vers la position ouverte, et un second ressort (8) également associé à la soupape (1) et tendant à s'opposer à son passage à la position ouverte. L'agencement est tel que lorsque l'électro-aimant (3) n'est plus excité, la soupape (1) se déplace de manière accélérée vers la position ouverte sous l'action du premier ressort (7) jusqu'à ce que ce dernier s'arrête, la soupape (1) se déplaçant alors de manière décélérée dans la position ouverte sous l'action du second ressort (8).
