Abstract

Dispositivo para el accionamiento de una válvula selectora de gas de un motor de combustión interna, el cual comprende un elemento hidráulico de compensación de holguras y un órgano actuador electromagnético, que posee un imán de apertura así como un imán de cierre, entre los cuales está dispuesta de forma axialmente desplazable una armadura que, mediante un resorte de apertura, actúa en contra de la fuerza de un resorte de cierre, sobre el vástago de la válvula selectora de gas; dispositivo de accionamiento éste que está caracterizado porque el resorte de apertura (15) es de una curva característica (27) más empinada así como de una más reducida tensión previa que el resorte de cierre (14); en este caso, la posición de equilibrio (19) corresponde al estar los imanes (2, 3) sin corriente aproximadamente a una posición central energética.
