Abstract

Los accionadores y los métodos y sistemas correspondientes para controlar tales accionadores, proporcionan al control de la válvula independiente una fuerza de abertura o inicial grande. En una modalidad ejemplar, el accionador incluye un impulsor que además incluye un alojamiento que define un eje longitudinal y una primera y segunda direcciones, el mecanismo de activación es capaz de generar la fuerza de activación por lo menos en la primera dirección y una biela con un extremo que se conecta en forma operativa con por lo menos una parte del mecanismo de activación y con otro extremo disponible para una conexión que puede operarse con una carga como una válvula del motor; por lo menos un resorte de retorno conectado en forma operativa con la biela a través de un ensamble de retén de resorte y que desvía la biela en la segunda dirección; y un reforzador neumático que además incluye un cilindro neumático, un pistón neumático conectado en forma operativa con la biela a través del ensamble de retén de resorte y que desvía la biela en la primera dirección, un mecanismo de carga que proporciona una comunicación fluida controlada entre el cilindro neumático y la fuente de gas de presión alta y un mecanismo de purga que proporciona una comunicación fluida controlada entre el cilindro neumático a un colector de gas de presión baja.
