Abstract

La presente invención se refiere a un sistema de componentes mecánicos que operan cooperativamente para controlar la evaporación del combustible o la fuga de hidrocarburos desde los motores. En al menos algunas modalidades, el sistema de componentes mecánicos comprende un primer ensamble de la válvula (2) y un segundo ensamble de la válvula (8) . El primer ensamble de la válvula, que funciona como un ensamble de la válvula de cierre, gobierna si el combustible puede proceder desde un receptáculo para el combustible (4) hacia un carburador (6), y cuando está cerrado, previene que los vapores del combustible se desarrollen dentro del carburador. El segundo ensamble de la válvula, que funciona como un "ensamble de la válvula de control para ventilar el vapor" tiene una abertura de entrada que es acoplada por medio de una manguera para el vapor del tanque de combustible a tanto el tanque de combustible como al receptáculo para el combustible. Cuando está en el estado cerrado, el segundo ensamble de la válvula controla los vapores del combustible, que son provistos a su abertura de entrada desde el tanque del combustible y el receptáculo para el combustible, para evitar que sean comunicados a una abertura de salida del segundo ensamble de la válvula.
